Multi-disciplinary projects, solving real-world problems with modern tech After a bright start to your career have you reached the limits of what your company can offer you? Maybe you’ve completed a graduate scheme but the department you’ve been assigned to doesn’t excite you? Or perhaps you just need a change? This agile company is looking for top hardware and electronics talent. They develop hardware and software systems for the defence community, typically within the radio communications, high-speed data processing and cyber security arenas. This requires skills in complex PCB design, FPGA development and embedded software. Unlike traditional defence companies, projects here have shorter timespans (months rather than years) providing you more variety and a constant stream of new areas to discover and learn about. Staffed by very bright and versatile engineers, they are looking for kindred spirits, so strong academics, curiosity and problem-solving skills are all critical. While nominally a hardware engineer you can expect to be involved in projects outside your speciality, maybe that’s writing some higher-level C/C++ code or writing a research paper about a particular technology. So having a breadth of knowledge and skills is valuable. Requirements: \* Commercial experience developing electronic hardware products \* Strong academics including a top degree in a numerate discipline (probably from a top 10 ranked university) and A’s or A\*’s at A-Level (further academic qualifications such as Master’s degrees or PhDs are well received) \* Ideally your commercial experience will come from working at a small company or similar where you’ve had to pick up new skills as required \* UK nationality and residency in the UK for the last 10-years Located in a picturesque town on the edge of the Cotswolds, this company offers a strong salary and benefits package with an enhanced company contribution pension scheme, private health care insurance and bonus scheme. Due to the nature of the work, this is a fully office-based position.
