Job Description:

Senior Hardware Engineer

If you enjoy solving complex engineering problems in safety-critical environments and want to see your designs move from concept through to real-world deployment, this could be YOUR next step.

This well-established, technology-driven organisation in the Cambridge area is investing heavily in its next generation of products and is looking to bring in an experienced Senior Hardware Engineer to strengthen a highly capable Baseband Hardware team.

You will be joining a collaborative, technically ambitious environment where engineers are trusted with ownership, encouraged to influence design decisions, and supported to develop both technically and professionally.

Why this role?

  • Work on technically demanding, safety-critical electronic platforms
  • Take real ownership of features and subsystems within major product developments
  • Be part of a stable, growing engineering group with long-term product roadmaps
  • Influence design decisions from early architecture through to verification
  • Collaborate with multidisciplinary teams across hardware, systems and verification

What you will be doing:

  • Owning delivery of defined product features or significant sections of larger platforms
  • Designing intrinsic safety circuitry for ATEX-certified products, including thermal management and current-limiting strategies
  • Developing microprocessor-based systems with integrated sensors
  • Creating efficient, low-power power-supply architectures for demanding operating environments
  • Designing audio amplifier solutions up to 10W
  • Leading design verification, EMC validation and system-level testing
  • Producing high-quality technical documentation to support release and certification
  • Working closely with cross-functional engineering teams

What we need from you:

  • A degree in an engineering discipline (or equivalent industry experience)
  • Proven experience developing hardware for ATEX-certified or intrinsically safe environments
  • Strong understanding of intrinsic-safety principles and regulatory compliance pathways
  • Experience with microprocessor systems, low-power architectures and power-saving strategies
  • Confidence across serial interfaces such as I²S, I²C, UART and USB (USB 3.0 particularly welcome)
  • The ability to communicate complex designs clearly through written technical documentation
  • A proactive, collaborative mindset and comfort working in evolving development programmes

An added bonus…….

  • EMC and ESD design experience at component and system level
  • Exposure to complex mixed-signal architectures
  • Audio system design experience
  • Familiarity with embedded Linux environments, board bring-up or driver integration

What can you expect in return:

  • Salary in the range of £65,000 – £85,000, dependent on experience
  • Private health and dental care
  • Subsidised onsite restaurant
  • Enhanced pension contribution
  • Flexible working hours
  • Employee assistance programme
  • Free onsite parking
  • Regular social events
