Real-Time Systems Software Engineer

Sun, 14 Jun 2026 10:05:40 GMT

Real-Time Systems Software Engineer

Based in Stevenage

Salary up to £65k

Some software engineering roles are comfortable. Familiar stack, predictable problems, another sprint planning meeting.

This isn't one of those.

You'll be writing C++ on Linux, working with high-speed SFPDP data pipelines and multi-threaded architectures that feed directly into the validation of some of the most advanced defence systems in the world. Real hardware. Real consequences. The kind of work that actually matters.

The team is small and experienced. No passengers. You'll own problems, make decisions, and see the results of your work in systems that get used.

What the role needs from you is straightforward: solid C++ and Linux, genuine experience with real-time data systems and concurrent programming, and the instinct to go deep when something isn't working. SFPDP experience is a bonus, not a dealbreaker.

You'll need to be eligible for UK Security Clearance and comfortable being based full-time on-site in Stevenage. The package includes: up to £2,500 bonus, 14% pension, flexi leave, and paid overtime.

If you've been building real-time systems and you want the work to mean something, this is worth a conversation.

Principal RF Engineer

Sun, 14 Jun 2026 10:04:57 GMT

You fire missiles indoors.

Not literally, but close enough that it counts.

The Hardware-in-the-Loop team at one of Europe's most respected defence primes runs the most complete test of a missile short of an actual firing. They build real-time simulations that wrap around live missile hardware, and they do it with a small, expert team who genuinely know their stuff.

They need an RF engineer who can design, develop, and maintain complex RF equipment, work across electronics and software, and hold their own in multi-disciplinary teams where the stakes are real.

You don't need to tick every box. Broad RF experience matters more than a perfect CV. If you've worked across RF design and testing, system integration, real-time applications, or hardware with embedded controllers, this could be a serious conversation worth having.

The role is based in Stevenage. Mostly on-site, for reasons you'll understand once you know the work. Up to £55k, a decent bonus, 14% pension, and flexi leave that's actually flexible.

SC clearance required. British citizenship essential.

If you've been in the same seat for a while and wondered what a proper technical challenge looks like, this is worth a look.

Most Manufacturing Engineers are good at the technical side. Fewer are good at the people side. This role needs both.

You'll be leading a team of Senior Manufacturing Engineers on a site that's growing, with real investment going in, production rates increasing, and a pipeline that isn't slowing down. That means your fingerprints will be on how this manufacturing function scales, not just how it runs.

Day to day: managing workloads, driving CI, representing the team at cross-functional forums, and getting involved in DfM conversations with the design authority early enough to actually make a difference. There's also genuine scope to get into manufacturing architecture and factory of the future concepts if that interests you.

You'll need a solid engineering background, experience interpreting design drawings and developing manufacturing methods, and the confidence to lead a team rather than just work in one. Defence or aerospace sector experience is an advantage; the right mindset and technical foundation matters more.

The role is site-based in Henlow, 4-5 days per week. Security clearance is required, so UK nationality is a pre-requisite.

The package is competitive: bonus up to £2,500, pension contributions to 14%, paid overtime, up to 15 days flexi leave, and a benefits stack that reflects the employer's intent to keep good people.

If you're currently a Senior Manufacturing Engineer ready to lead, or already at Principal level and looking for a role with real scope, this is worth a look.

Senior Structural Engineer

Fri, 12 Jun 2026 08:38:50 GMT

Senior Structural Engineer

Based in Bedfordshire

Salary between £45,000 - £51,000 + benefits

Most structural engineers will never touch the programmes this role sits on.

This is a Senior Structural Engineer position embedded in a Special Projects team working on some of the most operationally sensitive platforms in UK defence. The work is classified, the problems are genuinely hard, and the impact is real.

You will own complex structural analysis end-to-end, FEA modelling, damage tolerance, fatigue life, dynamic and thermal assessments, across metallic and composite structures. Your outputs will feed directly into design reviews, manufacturing instructions, and MoD submissions. You will not be checking someone else's work. You will be the expert in the room.

What you'll need

5+ years of structural analysis experience on metallic and composite structures. Solid FEA skills, MSC Nastran is the baseline, with any experience of Patran, Simcenter, ANSA a bonus. Confident with hand calculations, fatigue prediction, and writing clear, concise strength reports that stand up to scrutiny.

You will need to be eligible for, and willing to pursue, DV clearance. You can start on BPSS while the process runs.

Why this one?

Four-day week (Monday to Thursday). A small, technically strong team where your experience will be valued rather than lost. And the chance to work on programmes that actually matter.

If that sounds like the step you've been looking for, let's talk.

Software Engineer - Data Science

Tue, 09 Jun 2026 09:28:41 GMT

Software Engineer - Data Science

Based in Stevenage

Salary up to £65k + Overtime, Bonus, Pension

Most software engineers spend their careers shipping incremental updates to things that already exist.

This isn't that.

This role sits inside a concept programme, which means you're not maintaining a product roadmap, you're helping shape what comes next. You'll be working with complex datasets, building scalable systems with embedded data science capabilities, and translating experimental ideas into production-ready solutions.

If that sounds vague, it's intentional. The work is classified. What we can tell you is that it matters, the technical challenges are real, and the people you'll work alongside are genuinely good at what they do.

What you'll bring:

Strong software engineering fundamentals (C++, Java or similar), a solid grounding in data science or machine learning, and the kind of mindset that's comfortable in ambiguity. You don't need to have all the answers. You do need to be curious enough to find them.

Security clearance is required, so British citizenship is essential.

If the thought of working on something you can't talk about at dinner sounds more appealing than frustrating, we should speak.

Environmental Engineering Lead

Tue, 09 Jun 2026 09:27:41 GMT

Environmental Engineering Lead

Based in Stevenage

Salary Up to £57,000 + Bonus + Overtime + Pension

Most engineers talk about working on something that matters.

You'd be working on defence systems that defend nations.

This is a Domain Lead position sitting at the heart of a major defence programme, owning the full environmental engineering picture across a family of complex systems. Mechanical and climatic environments. Requirements through to qualification. Proving strategies, risk, schedules, budget, and a team of engineers looking to you for technical direction.

You won't be buried in a workstream. You'll be the focal point.

That means working directly with Systems, Verification, Mechanical Analysis, Architecture, and Quality, as well as engaging at Project Head and Chief Engineer level when the hard problems land. Your fingerprints will be on the design, the proving approach, and the decisions that matter.

What they're looking for is someone with solid environmental engineering experience in defence or a closely related sector, a working knowledge of DEF STAN 00-035 or Mil Std 810, and the credibility to lead without needing a title to do it. DOORS experience and a background in test processes and instrumentation will serve you well here.

The package is competitive: up to £57k, company bonus, 14% pension contribution, up to 15 days flexi leave, and hybrid working at three days on-site.

SC clearance is required, so British citizenship is essential.

If you're the kind of engineer who wants to own a domain rather than just work in one, let's talk.

Trials and Analysis Engineer

Tue, 09 Jun 2026 09:27:11 GMT

Trials and Analysis Engineer

Based in Stevenage

Salary up to £55k + bonus, overtime, pension, hybrid working

You've probably got a solid job. Decent team, familiar problems, work you can do in your sleep.

This role is for someone who wants to be technically stretched. You'll be working across land, sea and air defence systems at every stage of the product lifecycle, from concept through qualification and into in-service support. Real programmes. Real complexity.

The work covers vibration, shock and thermal analysis, data gathering trials, platform integration, and structural modal assessment. You'll write test specifications, evaluate data, produce recommendations, and own your technical decisions. Nobody's going to walk you through it.

To be right for this, you'll need a strong background in environmental or mechanical engineering, experience analysing systems in complex environments, and ideally some exposure to signal processing and instrumentation. The mindset matters as much as the CV: investigative, adaptable, and comfortable making calls under pressure.

Due to security clearance, you will need to be a British citizenship.

The package is competitive, and the work is genuinely interesting. Not many engineers get to say that.

If this sounds like the step forward you've been quietly looking for, let's talk.

The role sits inside a multi-disciplined software engineering team, and your job is to be the person who shapes how security is thought about, not just checked. That means influencing architecture decisions, coding standards, technology selection, and development methodology, working with engineers who take security seriously because the stakes demand it.

What the work looks like:

You'll conduct security assessments and threat analyses, develop mitigation strategies, and provide technical guidance to software and project teams. You'll have a say in which technologies and frameworks get adopted, and you'll help build the processes and documentation that make security repeatable across the product lifecycle. SC clearance is required, with willingness to progress to DV.

What they're looking for:

Experience in software security within defence, aerospace, automotive, or telecoms. You'll understand industry security standards and best practices, and you're comfortable leading technically as well as collaborating across disciplines. A STEM degree or equivalent experience, and an interest in emerging technologies and the security challenges they bring.

What's on offer:

Salary circa £74k, bonus up to 21%, pension up to 14% combined contribution, hybrid working, and a benefits package that includes enhanced parental leave and excellent on-site facilities.

If you're the kind of engineer who wants your security expertise to actually count, this is worth a conversation.

Engineering Project Coordinator (Electronics)

Wed, 03 Jun 2026 12:57:02 GMT

Engineering Project Coordinator (Electronics)

Stevenage | Hybrid | Up to £45,000 + Bonus + Flexi Leave

You’re working in engineering.

You understand projects.

But you’re not yet owning them.

This is your move.

The Opportunity

This isn’t a support role where you sit on the sidelines.

You’ll be embedded in real engineering projects, working alongside experienced Project Managers, learning how complex defence programmes are delivered, then stepping up to run your own.

You’ll get exposure to:

Full engineering project lifecycle
Bid and programme delivery
Supply chain coordination
Real-world project planning (Primavera P6)

This is a genuine pathway into an Engineering Project Manager role.

What You’ll Bring

You don’t need to be the finished article, but you do need the foundations:

Degree in Electronics or Engineering
Experience in an engineering or technical environment
Understanding of electronic product development
Exposure to project planning/scheduling/Excel
The ability to organise, influence, and keep things moving

Most importantly, you want to grow.

Why This Role Stands Out

Clear progression into Project Management
Learn directly from experienced PMs
Flexible working, including 4 or 5 days per week
Hybrid model, typically 1–2 days onsite
Strong benefits package including:
- Bonus
- Overtime
- Up to 14% pension
- Flexi leave (up to 15 days)

Due to security clearance requirements, you must be a British citizen or a dual national with UK citizenship.

The Bottom Line

If you’re an engineer who’s started to move toward project work, or a coordinator ready to step up, this is one of those roles that can shape your career.

Not in five years.

In the next one.

Lead Product Design Engineer

Wed, 03 Jun 2026 07:15:52 GMT

Lead Product Design Engineer

Based in Bristol

Up to £57,000 + bonus + strong package

If you’re an Engineer who wants more ownership, more visibility, and a product you can genuinely influence, this is worth a look.

This isn’t a narrow role. You’ll sit at the centre of a Command & Control system, the part that thinks, decides, and drives the capability of the entire system.

You’ll lead design across hardware and software, work across multiple programmes, and see your decisions move from concept through to delivery.

Recent export success means real investment, new customers, and complex integration challenges. It’s a chance to step into a leadership role where your input genuinely shapes the product.

What you’ll be doing:

Leading a small team delivering system and software design
Driving hardware and software integration across the product
Translating requirements into robust design baselines
Working across the full engineering lifecycle, from concept to test
Engaging with stakeholders across systems, software, and project teams

What you’ll bring:

Software design experience within a complex product environment
Ability to lead small teams
Understanding of the full development lifecycle (V-model)
Experience with tools such as DOORS, Rhapsody, or similar
Ability to lead, influence, and solve complex technical problems
Strong background in requirements, design, and integration

Why this role:

High-impact product at the heart of the system
Real technical ownership, not just coordination
Strong benefits package including bonus, overtime, pension up to 14%, and flexi leave
Long-term programme stability with ongoing investment

Security clearance requirements mean you'll hold British Citizenship or Dual Nationality with British citizenship.

If you want to move from contributing to owning, this is a strong step.

Validation and Verification Engineer

Wed, 03 Jun 2026 07:15:28 GMT

Systems V&V Engineer

Based in Bristol

Salary up to £55,000 + bonus + strong benefits

This isn’t just testing.

This is proving that a system designed to protect lives actually works when it matters most.

You’ll be working at the heart of a Command & Control system, the brains behind how threats are understood, prioritised, and dealt with in real time. Complex, high-stakes engineering where “good enough” simply isn’t.

What you’ll be doing:

Defining real-world test scenarios for complex systems
Setting success criteria that actually mean something
Verifying systems against requirements, not just ticking boxes
Working across the full lifecycle, with exposure to multiple engineering disciplines

What you’ll bring:

Systems Engineering experience on software-led products
Experience in verification, validation, or test environments
Familiarity with tools like DOORS, Rhapsody, or SysML helps, but isn’t essential

Why this role:

You see the whole system, not just your piece of it
You work on real defence capability, not theory
You’re trusted to think, not just follow process
You’ll be stretched, supported, and developed

On top of that:

Bonus, strong pension, paid overtime
Up to 15 extra days leave
Real investment in your development

You’ll need to hold current British citizenship and be eligible for UK security clearance.

If you want to work on systems that genuinely matter, and be part of proving they’re ready, this is worth a conversation.

Test Development Engineer

Wed, 03 Jun 2026 07:14:55 GMT

Test Development Engineer

Based in Bolton

Salary up to £43,000

You know your way around a circuit card. You've built automated test systems, you've written LabVIEW sequences, and you actually enjoy the problem-solving that comes with it.

Here's the thing, though: most test roles don't give you much beyond maintaining what's already there.

This one's different.

You'd be joining a well-established team, working across the full development cycle, from concept through to series production. That means test strategy, ITA design, software development, and real influence over how products are built through Design for Test.

It's the kind of role where your technical judgment actually shapes outcomes, not just monitors them.

What you'll be doing:

Developing and maintaining automated test systems for circuit card assemblies, writing test strategies and documentation, designing Interchangeable Test Adaptors (mechanical and electrical), and getting involved with continuous improvement and emerging technologies.

What they're looking for:

A solid grounding in analogue and digital circuit design, hands-on experience building ATE, and familiarity with LabVIEW and/or TestStand. Boundary Scan or XJTAG exposure is a plus. You'll need to be a British Citizen or be a dual national with British citizenship, due to security clearance requirements

What's on offer:

Salary up to £43,000 base, £2,500 company bonus, pension contributions up to 14%, hybrid working (3-4 days on-site), and a genuinely well-resourced site with subsidised meals, free parking, and more.

If you've been doing this kind of work and wondering whether there's somewhere it carries more weight, this is worth a conversation.

Most software engineers will never see their work matter in the way yours could here.

This team builds Command and Control software for some of the most advanced air defence systems in the world. Maritime. Real-time. Safety-critical. The kind of work where getting it right genuinely counts.

You'll be working hands-on across the full development lifecycle, contributing to C2 architecture design, embedded development, and the engineering of future products. The tech stack centres on Ada, though if your background is C++ or Rust, that's very much welcomed. Capable engineers pick up Ada quickly, and the team will support you through it.

The role is largely on-site in Bristol, which reflects the classification of the work rather than a lack of trust. If you know this sector, you understand.

The package is strong: salary to £60k, bonus up to £2,500, combined pension contributions to 14%, paid overtime, and up to 15 days additional flexi leave on top of your standard allowance.

Security clearance will be required. British nationality is essential.

If you've been developing in safety-critical or regulated environments, and you want your next role to mean something beyond the sprint board, this is worth a conversation.

Apply below, or reach out directly for a confidential discussion.
