A Contract position - Outside IR35

Hybrid working - 3 days on site

Our client, a pioneer in clean aviation technology, is currently seeking a Senior Electronic Hardware Systems Engineer to join their team on a contract basis and contribute to the development and qualification of airborne electronic hardware for Hydrogen Fuel Cell Management Systems.

Must have aerospace experience - airborne hardware, DO254. Somebody comfortable with the full design lifecycle from requirements writing through to delivery, familiar with DOA processes.

• Architect and integrate reliable monitoring and mixed‑signal electronics, including the elicitation of requirements and the generation of new derived requirements to support system‑level functionality and safety objectives.
• Collaborate with external suppliers on the detailed design and manufacturing of electronic hardware, ensuring appropriate component selection, generation of the required configuration‑control documentation and traceability, and adherence to design standards.
• Collaborate with Fuel Cell Systems, Mechanical, Software teams and other stakeholders to support the integration of hardware electronic circuit card designs.
• Own the design throughout the development cycle. Produce the required documentation for reviews, address findings, and perform follow‑up activities with internal and external stakeholders.
• Support compliance with DO-254 Plan objectives and activities for simple and complex electronic hardware, including documentation, traceability, verification, and validation processes.
• Produce and review design documentation to ensure traceability, compliance, and configuration control, in alignment with design processes and procedures.
• Maintain, review, and drive continuous improvement of engineering and design standards to ensure alignment with evolving aerospace best practices.

• Strong understanding of mixed signal circuit design and monitoring circuits.
• Strong understanding of electrical safety (creepage and clearance, insulation requirements, etc.).
• Skills in designing and implementing data acquisition systems.
• Experience with modelling electronic circuits using SPICE-based simulation tools.
• Proven experience in integrating electronics hardware with microcontrollers and digital signal processing.
• Understanding of qualification and environmental requirements (EMC testing, etc.).
• Bachelor's degree in Electronics Engineering, Electrical Engineering, or an equivalent professional experience in hardware electronics design.
• Experience in airborne hardware electronics development.

• Master's degree in Electronics/Electrical Engineering.
• Experience in fuel cell or battery management systems.
• Knowledge of physical implementation RS485, Ethernet and CAN communication interfaces.
• Experience working in a Design Organisation Approval (DOA).
• Familiarity with certification processes for aerospace systems and equipment under CS-25/CS-23, DO-254, and AMC 20-152A.
• Experience with IEC 60664, DO-160 or MIL-STD-810.
• Experience in modelling electronics using LTSpice, and/or Simetrix.
