Senior Electronics Hardware Systems Engineer

We are seeking a Senior Electronic Hardware Systems Engineer to join our team and take ownership of the architecture, integration, verification, and qualification of airborne electronic hardware for Hydrogen Fuel Cell Management Systems. The ideal candidate is a self‑motivated systems minded engineer who works independently, collaborates effectively across disciplines, seeks input from experienced colleagues, and consistently delivers high‑quality results in a timely manner.

In this role, you will be responsible for planning, defining, and developing both in‑house and outsourced high‑reliability electronic hardware architectures and concepts, in accordance with ZeroAvia standards and applicable aerospace regulations. ZeroAvia is at the forefront of a new clean aviation ecosystem, and the successful candidate will be joining a world‑class team that is passionate about designing and delivering solutions that are not just carbon‑emission free but also cost‑effective.

The Role:

• 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 ZeroAvia design standards.
• Collaborate with Fuel Cell Systems, Mechanical, Software teams and other stakeholders to support the integration of HW electronic circuit card designs.

HW Development Assurance Activities:

• Own the design throughout the development cycle.
• Produce the required documentation for reviews, drive, 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.

Process Assurance:

• Produce and review design documentation to ensure traceability, compliance, and configuration control, in alignment with ZeroAvia's design processes and procedures.
• Maintain, review, and drive continuous improvement of ZeroAvia’s engineering and design standards to ensure alignment with evolving aerospace best practices.

At ZeroAvia, we embrace the principle of "One Team, One Goal"—you will need strong communication skills and the ability to collaborate effectively across multidisciplinary design teams.

Technical Skills:

• Strong understanding of mixed signal circuit design and monitoring circuits.
• Strong understanding of Electrical safety (Creepage and clearance, insulation requirements, etc).
• Strong skills in designing and implementing data acquisition systems.
• Experience with modelling electronic circuits using SPICE-based simulation tools to assess and validate designs requirements.
• Proven experience in working and integrating Electronics Hardware with microcontrollers and digital signal processing.
• Strong understanding of qualification and environmental requirements (EMC testing, etc).

Experience Required:

• Minimum Bachelor’s degree in Electronics Engineering, Electrical Engineering, or an equivalent professional experience in hardware electronics design.
• 5+ Years Airborne Hardware Electronics Development Experience.
• Master’s Degree in Electronics/Electrical Engineering.
• Experienced 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 of 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.

At ZeroAvia, we’re clean sky thinkers. For the world to achieve truly clean, guilt‑free flight, we need a scalable solution; hydrogen‑electric powertrains. As a leader in zero‑emission aviation and a UK Jet Zero Council member, we’re designing and commercialising hydrogen‑powered solutions that will positively impact the future of aviation, global connectivity, and the world.

Engineering designs our next‑generation hydrogen electric engines. Working across Hydrogen, Propulsion and Integration divisions, they solve technical problems and help decarbonise aviation by finding solutions for electric propulsion, hydrogen storage, fuel cell technology, power distribution, thermal management and more.
