Hydrogen Fuel System Engineer

Join an innovative organisation at the forefront of zero-emission aviation as a Hydrogen Fuel Systems Engineer, playing a critical role in developing the next generation of gaseous and cryogenic hydrogen systems for aircraft.

In this role, you will own the end-to-end technical development of onboard hydrogen storage, distribution, and conditioning architectures, working at the cutting edge of engineering to enable safe, efficient, and certifiable hydrogen propulsion. From system design and integration through to testing, validation, and regulatory compliance, you will collaborate closely with cross-functional teams, suppliers, and partners to bring innovative hydrogen technologies from concept to flight-ready reality.

This position is integral to the organisation’s mission to accelerate the transition to clean aviation by eliminating carbon emissions from flight. By advancing robust, high-performance hydrogen fuel systems and ensuring their seamless integration into aircraft platforms, you will directly contribute to making zero-emission air travel commercially viable at scale. Your work will help overcome some of the most complex engineering and safety challenges in hydrogen aviation, supporting certification and enabling a sustainable future for aerospace., The Hydrogen Fuel Systems Engineer will:

• Own the design and development of gaseous and cryogenic hydrogen fuel systems, including storage, distribution, and conditioning architectures.
• Define, capture, and manage requirements at both system and component levels, including cryogenic storage vessels, valves, heat exchangers, lines, and safety-critical hardware.
• Support integration by defining system layouts, component packaging, and interfaces for onboard hydrogen systems.
• Lead supplier management and development activities for components within the hydrogen system, ensuring timely delivery, quality, and compliance with programme requirements.
• Evaluate supplier designs against performance, safety, reliability, and certification requirements by providing technical guidance and design oversight throughout the development lifecycle.
• Define and execute verification, validation, and testing strategies across hydrogen components, subsystems, and full system level.
• Oversee the operational management of hydrogen refuelling and testing facilities.
• Perform system architecture, safety analysis (FHA, FMEA, FTA, HAZOP, LOPA, DSEAR/ATEX), and performance validation, driving design improvements and technical decisions.
• Ensure compliance with aerospace regulations, industrial gas standards, and hazardous area practices.

• Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a related discipline, with strong experience in gas and cryogenic systems, including hydrogen and high-pressure environments.
• Proven expertise in designing, integrating, and testing gaseous and cryogenic hydrogen systems.
• Experience performing system sizing, analysis, and validation of gas systems using engineering modelling tools.
• Extensive knowledge of thermodynamics, fluid/gas dynamics, and system performance analysis.
• Hands-on experience with pressure testing, leak detection (e.g., helium), and validation of fluid and vacuum systems.
• Experience applying system safety and reliability methods (FHA, FMEA/FMECA, FTA) and using engineering tools such as ANSYS, MATLAB, Python, and CAD.
• Strong understanding of hydrogen safety, cryogenic systems, and relevant regulatory frameworks; aerospace or transportation sector experience is advantageous.
