Who we work with

 

We partner with:

• Defence primes and Tier 1 suppliers

• Specialist SMEs and high-growth technology businesses

• Safety-critical engineering and manufacturing organisations

• R&D and innovation-led teams

 

Most of our assignments require candidates to be eligible for UK security clearance, often SC or above. We understand the eligibility rules, transfer considerations and common delays, and we build this into the hiring strategy from day one.

 

What makes Cirrus Selection different

 

We shortlist on evidence, not keywords
Every candidate is screened in detail against technical depth, project exposure, lifecycle experience and motivation, not just job titles.

 

We understand clearance realities
Eligibility, nationality constraints, clearance transfer risk, notice periods, we manage this proactively so there are no surprises at offer stage.

 

We bring market insight early
If your salary, location or expectations are misaligned, your brief is too broad, or your timeline is unrealistic, we will tell you upfront. That saves weeks.

 

We manage the process properly
From initial outreach through to offer, notice period and start date, we protect candidate engagement and keep momentum high.

 

Market Reality

 

The UK market for experienced engineering professionals in defence, aerospace, advanced technology and safety-critical sectors remains highly competitive.

 

Many candidates are not actively applying for roles and must be engaged through targeted search. Long notice periods, clearance eligibility constraints and salary competition across organisations further reduce available talent pools.

 

Companies that approach hiring with clear requirements, realistic salary positioning and structured recruitment processes secure stronger outcomes.

 

Our Recruitment Process

 

A structured, transparent approach that protects quality and delivery.

 

1. Role Calibration and Briefing

We define what “good” looks like, separating must-haves from trainable skills. We align on salary, clearance constraints, reporting lines and interview process before we go to market.

 

2. Market Mapping

We identify target companies, job title variants and geographic realities. Where needed, we provide a snapshot of likely availability and salary expectations.

 

3. Search and Engagement

We use a combination of network search, targeted outreach and advertising. Messaging is tailored, not generic, particularly when engaging passive, security-cleared engineers.

 

4. Technical and Motivational Screening

We explore:

• Depth of engineering exposure

• Lifecycle experience

• Tools and standards familiarity

• Project scale and complexity

• Reasons for moving

• Clearance eligibility and constraints

 

5. Structured Shortlist

You receive a concise, evidence-based summary highlighting alignment, risks and considerations. No guesswork.

 

6. Interview and Feedback Management

We prepare candidates properly, manage expectations and ensure feedback flows both ways, quickly and clearly.

 

7. Offer, Notice and Onboarding Support

We handle counteroffers, resignation strategy and candidate engagement through notice and clearance processes to protect your hire.
