Hands-on senior designer in a mission-driven electronics team developing the next generation of material-characterisation laboratory instruments and sustaining the existing product range. You will own subsystems from requirements to verified hardware: low-noise detection front-ends, power distribution, MCU- and FPGA-based control boards, and the integration of cables, actuators and motors. You bring the two things the team needs most: a structured product-design approach and high-speed digital / Xilinx FPGA capability.
What you will do
- Design and verify circuits for the new instrument: low-noise analogue front-ends, mixed-signal, power and control boards.
- Own high-speed digital and FPGA/SoC (Xilinx Zynq) design, and PCB design in Altium 365 to IPC standards.
- Take technical ownership of the electronics architecture for your subsystems, from early concept through prototype, verification and product release.
- Run the product-design process for your subsystems: hardware and product requirements (HRS/PRS), design proposals, design reviews, DFMEA, verification plans and reports.
- Prototype quickly — breadboards, proto and rework boards — to validate concepts ahead of full PCBA spins.
- Bring up, debug and validate boards on the bench with the firmware team; solder, modify and test hardware yourself.
- Own the electrical BOM, component datasheets and the related safety/EMC considerations; support DFM/DFA as designs move from prototype to production.
- Sustain released products: obsolescence and alternates, manufacturing and field issues, root cause.
- Work with optics, mechanics, firmware, software and scientists to prove out designs; coordinate cross-functional issue resolution.
- Degree in electrical/electronic engineering or a closely related discipline; 5+ years of design engineering in instrumentation or test & measurement products.
- Mixed-signal design in a low-noise environments.
- Digital hardware: MCU-based control boards and communication interfaces — 1G/10GEthernet, USB, SPI, I²C, UART/RS-232, RS-485, CAN, PCIe.
- High-speed multilayer (8+ layer) digital design from schematic to PCB, including DDR3/DDR4 memory interfaces; FPGA/SoC design on Xilinx Zynq in VHDL or Verilog.
- Schematic and PCB design in Altium 365 to IPC-2221 / IPC-7351 with managed-library and version-control discipline; design for manufacture and assembly with a contract manufacturer, including DFM checks (e.g. Valor NPI) and Gerber review (e.g. ViewMate).
- Hands-on PCBA bring-up, test and troubleshooting with digital oscilloscopes, DVMs, spectrum, and logic analysers; test rigs and test plans; disciplined root-cause analysis. Not afraid of practical work — tinkering with circuits and debugging on your own initiative.
- EMC and product safety for laboratory equipment: IEC 61326-1 and IEC 61010-1, through to passing compliance testing.
- Structured product-design approach: requirements, design reviews, DFMEA, verification plans and reports.
- Obsolescence management and sustaining of released products.
- System-integration mindset: how a board fits the rest of the system — cabling, connectivity, harnessing, system diagrams — not only what it does.
- Experience with power supply design.
- Working with suppliers and manufacturers: quotes, cost comparisons, assembly options.
- Familiarity with PLM and task-tracking tools.
- Git and Git-based workflows; lean product development with Jira and Confluence.
- Applied use of AI tools and agentic workflows in engineering work
- UV instruments and high-voltage lamp drivers; thermal control and thermal-equipment design.
