Electronics Engineer

Most hardware engineers wait years to see anything they design reach operational use. Here, the electronics you design go into systems on operations today, and you will own how they get built rather than inherit someone else's process.

Minerva Defence is a UK sovereign defence technology company building the full stack of unmanned systems for modern warfare: hardware, software, networking, autonomy, navigation and effectors. Our mission is simple: to help ensure the UK and its allies can defend themselves in an era where major conflict is no longer unthinkable.

We are deliberately low-profile: no hype, no performative marketing, just execution. We ideate, design, and manufacture from start to finish right here in the UK. Our products are in active use on the battlefield today, delivering real operational impact in the most demanding environments. Despite operating largely in stealth, our team of 60 people is delivering disproportionate effect, with tens of millions in annual revenue across UK and non-UK customers.

Our culture is elite, innovative and mission-focused. We are built to be asymmetric: small in headcount, relentless in execution, and outsized in battlefield impact. We are looking for people who are not just talented, but committed: to the work, to the team, and to the purpose behind it.

You will own electronic hardware end to end, from a blank schematic to a product that performs reliably in the field. The role is still being shaped, so you will set the standard as you go: write the procedures, define the review process, and grow a small team around you. What you design reaches operational use in weeks and months, not years and decades, and the way it gets done is yours to define rather than handed down.

Responsibilities

• Design analog and digital circuits, and produce the schematics behind them
• Take hardware from first prototype through testing and debug to a validated design
• Lead PCB layout reviews for signal integrity, EMI/EMC, and manufacturability
• Own power design: DC-DC, LDO, and battery and charging systems
• Own the BOM, documentation, and revision control, including engineering change orders
• Support manufacturing, production, and suppliers as designs go to build
• Work alongside firmware, mechanical, and systems engineers to make the whole system perform

Requirements

Minimum:

• Experience designing analog and digital electronic circuits, from schematic through to validated hardware
• Strong hands-on lab and debugging skills: oscilloscope, DMM, logic analyser, soldering and rework
• Power electronics experience: regulators, protection, battery and charging systems
• A track record of component selection and BOM ownership, balancing availability, cost, and alternates
• Eligible for UK SC clearance (UK citizen or 5+ years UK residency)
• Willing to work on site in Herefordshire at least three days a week

Preferred:

• PCB layout experience and a working grasp of EMI/EMC and ESD reliability
• Experience taking hardware through manufacturing and into production
• Experience mentoring or coaching engineers and establishing processes and standards within a growing team
• Evidence of hands-on engineering interests outside work: cars, 3D printers, robotics
• An interest in aerospace or aviation

Benefits

We try to take the everyday pressures off your plate, so you can do your best work without worrying about the noise, and the benefits are built around that. It starts with real ownership: share options that vest over three years, so you hold a genuine stake in what we are building. You get a Claude Team account on day one and tools that keep up with you. Bupa private health is fully funded from your first day, the pension is a 6% employer contribution, and leave is generous, with 25 days plus bank holidays, your birthday off, and properly enhanced cover for both parents. The full detail comes with your offer.
