If you've served in the RAF, Royal Signals, 14 Signal Regiment, REME or another defence communications or infrastructure role, and enjoy solving technical problems where reliability really matters, we'd like to hear from you. We're recruiting a Field Service Engineer to support advanced defence technology across secure customer sites throughout the UK for a client who are a leading tech and engineering firm operating within defence.
This isn't a desk-based support role.
You'll be out with customers maintaining critical systems, supporting military exercises, carrying out technology upgrades, diagnosing complex faults and ensuring operational capability is always maintained. Whether your experience comes from deployed operations, secure headquarters, NATO exercises or supporting classified infrastructure, your background is highly relevant.
