Defence and aerospace recruitment demands more than generic agencies pushing candidates. It requires deep sector knowledge, security clearance expertise, IR35 mastery, and genuine understanding of the competitive landscape you operate in. White Onyx was founded on a simple motif: defence and aerospace recruitment deserves better.
White Onyx operates exclusively within defence, aerospace and advanced engineering sectors. Our consultants specialise in distinct domains, continuously developing comprehensive knowledge of technologies, qualification requirements, clearance pathways, and industry structures within our sector specialisms.
This is not transactional recruitment. We operate as embedded advisors, providing sustained support to organisations requiring access to cleared personnel, specialist engineering and technical talent, and programme-critical skillsets. Our approach is methodical, compliant, and focused on long-term capability building rather than short-term placement volumes.

The Sectors
We Serve
Land defence encompasses the platforms, systems, and technologies that deliver ground-based military capability - from main battle tanks and armoured fighting vehicles to C4ISR systems, ground-based air defence, artillery, and emerging autonomous ground vehicles. The UK's land defence sector is experiencing significant transformation as programmes like AJAX, Boxer, Challenger 3, and next-generation battlefield management systems demand engineers and specialists who understand not just mechanical and electrical engineering, but the integration of cyber, communications, autonomy, and lethality into complex land platforms.
White Onyx specialises in recruiting across the full land systems domain - whether you're developing next-generation armoured vehicles, integrating battlefield networks, designing protection systems, or delivering through-life support for in-service platforms. We understand the technical disciplines, clearance requirements, and programme structures that define land defence recruitment.
Air defence encompasses the platforms, systems, and technologies that deliver air-based military capability - from fast jets and transport aircraft to helicopters, unmanned aerial systems, avionics, mission systems, and the complex integration of sensors, weapons, and communications that enable air dominance. The UK's air sector is experiencing transformation as Tempest progresses, F-35 integration continues, and next-generation autonomous systems development accelerates.
White Onyx specialises in recruiting across the full air domain - whether you're developing next-generation combat aircraft, integrating mission systems, designing avionics, or delivering through-life support for in-service fleets. We understand the technical disciplines, clearance requirements, and programme structures that define air systems recruitment.
Naval and maritime defence encompasses the platforms, systems, and technologies that deliver sea-based military capability - from aircraft carriers and destroyers to submarines, mine countermeasures vessels, autonomous maritime systems, and the complex combat systems that integrate sensors, weapons, and communications into coherent fighting platforms. The UK's naval sector is experiencing a period of sustained investment as Type 26 frigates enter production, Type 31 frigates commence build, Dreadnought-class submarines progress, and the Royal Navy maintains and upgrades its surface and subsurface fleets.
White Onyx specialises in recruiting across the full maritime domain - whether you're designing next-generation frigates, integrating sonar systems, developing submarine propulsion, or delivering through-life support for in-service vessels. We understand the technical disciplines, clearance requirements, and programme structures that define naval recruitment.
The space domain is experiencing unprecedented growth as sovereign space capability becomes a national security imperative. From satellite communications and Earth observation to space domain awareness, launch systems, and future space-based defence capabilities, the UK is investing significantly in space infrastructure, technology, and human capital. The UK Space Agency, MOD Space Command, and a thriving commercial space sector are creating sustained demand for space systems engineers, satellite specialists, and space mission professionals.
White Onyx specialises in recruiting across the space sector - whether you're developing next-generation satellites, designing ground segment infrastructure, working on launch systems, or delivering space domain awareness capabilities. We understand the unique technical disciplines, clearance considerations, and programme structures that define space recruitment.
Cyber security has evolved from a niche technical discipline to a critical national security capability underpinning all defence operations, platforms, and infrastructure. From protecting classified networks and securing weapon systems against cyber attack to offensive cyber operations and critical national infrastructure defence, the UK's cyber security sector operates at the intersection of technology, intelligence, and warfare. The National Cyber Security Centre (NCSC), GCHQ, MOD, and defence industry all face sustained, critical demand for cyber security professionals with appropriate clearances and technical depth.
White Onyx specialises in recruiting across the cyber security and information assurance domain - whether you're defending classified networks, conducting penetration testing, developing secure software, or working in cyber intelligence. We understand the technical disciplines, clearance imperatives, and organisational structures that define cyber security recruitment.
Systems engineering is the integrating discipline that transforms complex sets of requirements, technologies, and stakeholder needs into coherent, functioning systems. From combat aircraft and warships to satellites and battlefield networks, every major defence platform and programme depends on systems engineers to define requirements, manage interfaces, integrate subsystems, and verify that the delivered capability meets operational needs. As defence programmes grow in complexity - integrating cyber, autonomy, AI, and networked warfare - systems engineering has become the most critical and sought-after engineering discipline in UK defence.
White Onyx specialises in recruiting systems engineers across all defence domains - whether you're working on Type 26 frigates, Tempest combat aircraft, military satellite systems, or autonomous platforms. We understand the methodologies (MBSE, V-model, Agile), the tools (DOORS, Cameo, Jama), and the standards (ISO 15288, DEF STAN 00-56) that define systems engineering practice.
Intelligence analysis underpins national security decision-making, military operations, and threat assessment across UK defence and security organisations. From all-source intelligence fusion and geospatial analysis to signals intelligence and targeting, the intelligence community and its supporting defence industry ecosystem require analysts with deep domain expertise, appropriate clearances, and the analytical rigour to transform raw intelligence into actionable insight.
White Onyx specialises in recruiting across the intelligence analysis domain - whether you're working in all-source fusion, imagery analysis, SIGINT, targeting, or strategic intelligence. We understand the disciplines, clearance imperatives, and organisational structures that define intelligence recruitment.
Artificial intelligence, machine learning, and data science are transforming defence capabilities - from autonomous systems and intelligent targeting to predictive maintenance and intelligence analysis. The UK's defence AI strategy, backed by significant investment, is creating sustained demand for AI engineers, data scientists, and machine learning specialists who can apply cutting-edge techniques to operational defence problems. This is a sector where commercial tech companies, academia, and defence compete intensely for the same scarce talent pool.
White Onyx specialises in recruiting AI and data professionals for defence applications - whether you're developing autonomous vehicles, building intelligence data pipelines, applying machine learning to sensor fusion, or researching next-generation AI capabilities. We understand both the technical disciplines and the unique challenges of applying AI within defence constraints (explainability, safety, adversarial robustness, classification).
