Senior Hardware Engineer

Location: East Cambridgeshire
Employment Type: Full-time, Permanent
Salary: £65,000-£70,000

A growing technology and engineering business is looking for a Senior Hardware Engineer - Electronics to join its R&D team.

The successful candidate will play a key role in developing complex electronic products, taking projects from initial concept and requirements through to design, prototyping, testing and production.

This is a hands-on senior engineering position suited to someone with strong electronics design experience who can work across analogue, digital and embedded hardware.

• Own electronics development from initial concept through to production.
• Design low-noise analogue, digital and mixed-signal circuits.
• Develop hardware incorporating microprocessors, microcontrollers and FPGAs.
• Design production-ready multi-layer PCBs, considering signal integrity, power integrity and thermal performance.
• Carry out schematic capture, component selection, simulation, PCB design and prototype development.
• Lead board bring-up, fault finding, testing and design verification.
• Develop and optimise power supplies, protection and power-management systems.
• Ensure designs meet relevant EMC, safety and regulatory requirements.
• Lead design risk assessments and contribute to DFM and DFT activities.
• Work closely with firmware and software engineers across the hardware/firmware interface.
• Produce technical documentation, BOMs, drawings and verification records.
• Support project planning, technical proposals and cost/effort estimates.
• Work collaboratively within a SCRUM-based multidisciplinary R&D environment.
• Support customer-facing technical discussions and prototype demonstrations where required.

• Degree or equivalent qualification in Electronics, Electrical Engineering or a related discipline.
• 5+ years' commercial experience in full product lifecycle electronics R&D.
• Strong analogue electronics design experience, particularly with low-noise and high-frequency circuits.
• Experience with digital and mixed-signal hardware.
• Experience with FPGA, microprocessor and microcontroller-based systems.
• Strong PCB design experience, ideally using Altium.
• Experience designing multi-layer PCBs and understanding signal integrity, grounding, shielding and thermal considerations.
• Knowledge of high-speed communication interfaces such as LVDS, Ethernet, USB, SPI and I²C.
• Experience with power-supply design and power integrity.
• Strong practical laboratory skills, including the use of oscilloscopes, spectrum analysers, logic analysers and signal generators.
• Understanding of EMC, DFM, DFT and product compliance.
• Strong problem-solving skills with the ability to take ownership of projects through to completion.

Experience in any of the following would be beneficial:

• Complex measurement, sensing or imaging equipment.
• High-frequency or precision measurement electronics.
• Transducer drive/receive electronics.
• Taking electronic products through EMC and safety testing.
• CE/UKCA certification.
• Mixed-signal simulation such as SPICE.
• MATLAB or Python for engineering analysis and automated testing.
• Experience working within an agile/SCRUM environment.
