Senior Electronics Engineer Location: Derby Salary: £40,000 - £50,000 dependant on level of experience plus package including; 37-hour work week with an early Friday finish. 28 days holiday (including bank holidays), with Christmas shutdown. Technical leadership within a highly respected team supporting national rail infrastructure. Long-term career development with continued investment in R&D and innovation. Summary A leading specialist resolution provider of electronic and electro-mechanical assemblies within rolling stock and varying other sectors are looking to hire a technically accomplished Electronics Engineer to join a growing engineering team delivering robust, high-reliability electronic solutions to the UK rail industry. This is a hands-on role covering the full product lifecycle - from concept, design, and embedded firmware development through to fault diagnostics and legacy system refurbishment. The successful candidate will work across a range of rolling stock, traction, and control systems, often where components are obsolete and require creative engineering approaches. You'll operate in a safety-critical environment where best practice, quality, and compliance matter - and where your experience and judgement will be trusted to lead both projects and people. Responsibilities Lead the design and delivery of electronic hardware and firmware projects for rail-based systems. Design, prototype and layout analogue and digital circuits (including high-speed designs). Develop embedded firmware in C, C++ and/or Python for 8-bit and 32-bit microcontrollers (PIC, AVR, ARM, TMS320). Carry out detailed diagnostics, reverse engineering and repair of legacy or obsolete systems. Use simulation and modelling tools (SPICE, Matlab, Simulink) to optimise control and thermal performance. Supervise junior engineers and apprentices, fostering a strong safety-first engineering culture. Implement safe working practices when handling high-voltage or high-power systems. Liaise directly with customers to gather requirements, assess feasibility, and manage expectations. Essential Skills & Experience Degree or equivalent qualification in Electronic/Electrical Engineering. Minimum 5 years of relevant hands-on experience in electronic hardware and firmware development. Strong track record in the rail sector or other high-reliability/safety-critical industries. Solid knowledge of analogue/digital electronics, PCB layout (KiCad, Altium or equivalent), and schematic capture. Experience working with high-voltage or high-power rail electronics (e.g. traction inverters, power converters). Appreciation of a strong "safety culture": safe use of power tools, voltages, and high-power plant, with ability to lead by example. Understanding of risk assessment methods and safe systems of work. Proven ability to liaise with customers and manage technical communications clearly and effectively. Practical workshop skills, SMD and through-hole soldering, wiring harness design/assembly, crimping, and machining. Desirable Technical Skills Experience organising and delivering complex hardware and/or firmware projects without compromising performance. Knowledge of control systems theory (H∞, LQR, etc.). Firmware development to industry quality standards (e.g. MISRA). Familiarity with in-system debugging tools (JTAG, SWD). Experience developing high-reliability or mission-critical systems for rail, defense, medical or nuclear sectors. Competence with diagnosing and restoring obsolete or unsupported equipment.
