Senior Electronics Engineer

About this role

SENIOR ELECTRONICS ENGINEER FULL-TIME | ENGINEERING LOCATION: CALMSDEN, CIRENCESTER, UK - WITH FIELD TRAVEL THE LAST FRONTIER The Arctic is a place of extremes: unforgiving, untamed, and undergoing rapid change. A literal defrosting reveals a multi-trillion-dollar opportunity spanning energy, defence, logistics, research, and infrastructure. ARD was founded on a paradox. The Arctic is both the next great economic frontier and one of the most hostile environments on Earth. Rich in resources and strategically vital, yet bone-chillingly cold, dark for months, and fundamentally inhospitable to humans. This paradox—an explosion of activity in a place that resists human presence—is why we exist. Our solution is autonomy. We build systems that operate reliably and intelligently in the Arctic, so that humans don't always have to. Founded by record-holding pioneers with decades of polar experience, we take calculated risks on hard problems that matter. If you want to build and deploy ground-up technology with real-world impact, at an inflection point in history that won’t reappear, we’d like to talk. THE ROLE We’re looking for a Senior Electronics Engineer to design, build, and test all electrical systems within ARD’s product stack. You’ll work at the intersection of hardware, software, and real-world deployment making an impact at every layer – from the PCB to Arctic field tests. You’ll move fast and take end-to-end ownership in the electronic architecture you’ll build, ensuring seamless operation in the harshest climate on Earth. CORE RESPONSIBILITIES - Architect, build, and iterate embedded systems from first principles - including MCUs, PCBs, physical comms modules, and ARD’s custom subsystems - Own electrical integration across ARD’s full stack, optimising for SWaP-C at every iteration - Serve as the go-to technical lead across electrical, RF, systems, and mechanical interfaces - Work tightly with deployment, software, and systems teams to ship field-ready hardware - Get hands-on in field – travel to Arctic test sites and client installations WHAT WE VALUE - 7+ years of hands-on experience building electronics for real-world systems – ideally with exposure to battery-powered platforms, RF comms (MANET, LoRa), and pLEO/GEO satellite systems - Proven track record designing and debugging high-density, high-reliability PCBs for harsh environments - Degree in Electrical Engineering, or a related field, with a portfolio ready to demonstrate - Skilled in RF testing and analysis (Spectrum analyser, Network Analyser, etc) and RF simulation tool suites - Confident soldering, PCB design, prototyping, and field-testing under pressure - Track record of delivering systems from sketch to deployment — managing time, cost, and complexity - Field-ready mindset — you're comfortable testing gear in sub-zero environments WHAT WE OFFER - Competitive compensation - Private health insurance - Dental & Optician - Equity — meaningful options as an early employee at an early-stage company - Real field exposure — travel to Arctic sites and Outposts when needed (genuinely, not as a gimmick) - Mission-driven culture — focus on impact, not hours logged - Small team, real ownership — what you build matters and ships A note on who we want to hear from We're building for one of the most demanding environments on Earth and we believe diverse teams build more resilient systems. We actively welcome applications from people who are underrepresented in engineering - whether that's by gender, ethnicity, disability, or background. If you're not sure you meet every requirement, apply anyway and tell us what excites you about the problem.
