• Proven experience delivering complex systems in secure, regulated environments
• Expertise in systems engineering tools, methods, and the full development lifecycle
• Strong problem-solving, documentation, and communication skills
• Comfortable balancing hands-on engineering with leadership and project oversight

• 7+ years’ experience in relevant sectors
• Background in electronics, embedded, RF, mechanical, or software engineering
• Familiarity with Concept of Operations development and systems-level modelling
• Exposure to defence, surveillance, or communications technologies

Salary & Benefits

• Salary: £60,000 – £65,000 (depending on experience)
• Annual Bonus: 3–6% of salary
• Holidays: 25 days (plus option to purchase 5 additional days via salary sacrifice)
