Job Description:

Job Title: Hardware Engineer (Avionics & Embedded Systems)

Location: Salisbury ( Hybrid-2 days a week in office)

Clearance Requirement: UK SC Cleared or SC Eligible

Role Overview We are an innovative Original Equipment Manufacturer (OEM) based in Wiltshire, specializing in advanced Uncrewed Aerial Systems (UAS). We are seeking a highly skilled Hardware Engineer to take ownership of the end-to-end design, multi-layer PCB layout, prototype bring-up, and environmental qualification of safety-critical flight control electronics, platform management computers, and sensor payload interfaces for fixed-wing, VTOL, and gas-turbine platforms.

Key Responsibilities

• Schematic & PCB Design: Create multi-layer rigid and flex-rigid PCBs using Altium Designer for flight control computers, power distribution units (PDUs), and sensor interfaces.

• Avionics Bus Integration: Implement robust, low-latency communication bus architectures, including CAN / CAN FD, RS422, RS485, Ethernet, SPI, and I2C.

• Power Electronics: Design low-voltage DC-DC converters, switching regulators, and power distribution circuitry optimized for weight, thermal dissipation, and efficiency.

• Board Bring-Up & Verification: Lead hands-on prototype bring-up, fault isolation, and hardware-in-the-loop (HITL) bench testing using standard laboratory equipment.

• Environmental & EMC Qualification: Design for harsh operating environments, ensuring compliance with RTCA DO-160G, DEF-STAN 59-411, and MIL-STD-810.

• Design Assurance: Produce comprehensive technical documentation (ICDs, DFMEA, BOMs, Gerber files) operating under ISO 9001 / AS9100 quality frameworks.

Required Skills & Experience

• Education: Degree in Electronic Engineering, Electrical Engineering, or Mechatronics.

• CAD Tools: Advanced proficiency in Altium Designer (Schematic Capture, Multilayer High-Speed PCB Layout, Controlled Impedance, DRC).

• Silicon Architecture: Proven experience with ARM Cortex-M microcontrollers (e.g., STM32) and microprocessors. Optional FPGA integration experience (Xilinx/Altera) is highly desirable.

• Test & Measurement: Hands-on expertise in electronic diagnostics, soldering, EWIS harness integration, and bench-test automation (Python/LabVIEW).

• Security Clearance: Due to the nature of the projects, candidates must have the ability to obtain and maintain UK Security Clearance (SC).
