Why this role will interest senior test engineers
Were supporting a long-standing UK MOD partner delivering advanced missile systems, and were looking for a Senior or Principal-level Test Engineer who wants to step into a true system-level architecture role.
This position is ideal for experienced engineers from test equipment, BIT, production test, or system verification backgrounds who want greater technical authority, broader influence, and visibility across the full product lifecycle from early design through manufacture and in-service support.
Youll work closely with the Chief Design Engineer and act as the lead test authority within multidisciplinary teams, shaping how complex missile systems are tested, diagnosed, built, and supported in service.
What youll be responsible for
* Defining and owning the system-level test strategy, balancing cost, coverage, and diagnostic effectiveness
* Architecting Built-In Test (BIT) solutions, including coverage requirements, timings, and system routines
* Specifying factory pass-out and production test stages, ensuring testability is designed into manufacture
* Defining in-service test concepts to support maintainability and supportability
* Translating high-level test intent into clear lower-level requirements for design teams
* Analysing and modelling systems to evaluate test coverage and fault diagnosis
* Advising on cost vs test-coverage trade-offs alongside the Chief Design Engineer
* Planning and coordinating test-related activities across internal teams and suppliers
This is not a delivery-only role you will shape decisions that influence the system architecture.
