Location: Luton
Job Description:

Job Description

Salary ranges: Engineer £38k–£53k, Senior £45k–£61k, Principal £54k–£71k, Lead £60k–£84k. Laurentian UK operates a grade‑based salary framework with broad bands; the salary range shown reflects the approved grade band for this role, or a narrower hiring range published within that band.

Your Impact

Work on mission‑critical electronics at the heart of next‑generation Electronic Warfare and advanced sensing systems. Based primarily at our Luton and Bristol sites, you’ll design hardware that must perform at the edge of what’s physically possible—high‑speed, low‑noise, highly integrated and ultra‑reliable—across challenging operating environments.

Responsibilities

  • Own and influence hardware designs across the full lifecycle—from system requirements and architecture through detailed design, testing, integration and customer delivery.
  • Design and develop complex, high‑performance electronics including high‑speed digital and mixed‑signal PCBs, FPGA, SoC and microprocessor‑based architectures, and high‑speed serial interfaces and interconnects.
  • Translate system‑level requirements into robust, producible hardware solutions.
  • Lead or significantly contribute to design reviews, trade studies and technical decision‑making.
  • Integrate in‑house designs with COTS modules (power, compute, RF and high‑speed interfaces).
  • Drive debug, test and verification activities at board and system level.
  • For Principal and Lead engineers: Provide technical leadership and mentoring within the team.
  • Shape hardware strategy, standards and best practice across programmes.
  • Collaborate daily within multi‑disciplinary teams spanning systems, firmware, software, RF and manufacturing.

Career Growth

This role offers increasing impact with capability. Senior engineers own complex end‑to‑end designs, solve hard technical problems with minimal oversight, and become go‑to experts. With experience, engineers naturally progress to Principal or Lead roles, shaping system and hardware architecture, setting technical direction and guiding design standards, while mentoring teams and influencing programme decisions.

Qualifications & Experience

  • Proven industry experience as a Senior, Principal or Lead Hardware Engineer.
  • Strong background in high‑speed digital electronics, mixed‑signal or high‑performance analogue design, or power electronics/low‑noise power architectures.
  • Hands‑on experience designing high‑speed PCBs, including schematic capture, layout oversight and simulation.
  • Experience with FPGA, SoC or microprocessor‑based designs.
  • High‑speed serial links and protocols (PCIe, Ethernet, JESD‑class interfaces).
  • Practical expertise in hardware bring‑up, debug, test and verification.
  • Ability to interpret and derive hardware designs from system‑level requirements.
  • Strong understanding of Design for EMC/EMI in demanding environments.
  • Experience integrating hardware, firmware and software into working platforms.
  • Comfortable within a structured hardware development lifecycle and configuration‑controlled environment.

Valuable (but not essential):

  • Experience in EW, radar, sensors or other complex defence systems.
  • Background in automotive, medical, aerospace or high‑reliability industrial electronics.
  • Experience with low‑noise analogue design, power supplies or signal integrity.
  • Use of model‑driven engineering approaches (MATLAB / Simulink).
