Hydrogen Fuel System Engineer

Our client, a pioneering company in the aerospace industry, is looking for a Hydrogen Fuel System Engineer to join their dynamic team on a contract basis. The company is focused on developing hydrogen-electric propulsion solutions.

Key Responsibilities:

• Contribute to the technical development of gaseous and cryogenic hydrogen fuel systems for aircraft, including storage, distribution, and conditioning architectures.
• Support aircraft integration activities, contributing to system layout, component placement, packaging, and interface definition for onboard hydrogen systems.
• Work closely with suppliers and partners to ensure on-time delivery and technical compliance of hydrogen storage tanks, cryogenic transfer systems, and gas conditioning subsystems.
• Contribute to the definition, optimisation, and execution of test strategies, including in-house capability development versus outsourcing, and assist in the operation and management of LH₂ and GH₂ test facilities.
• Plan and execute verification and validation (V&V) activities across component, subsystem, and system levels, including the development of test procedures, work instructions, and risk assessments.
• Analyse, verify, and validate the performance of hardware and associated control systems, initiating corrective actions and driving continuous improvement.
• Perform system architecture, functional analysis, and safety assessments across hydrogen fuel system concepts, supporting trade studies and design decisions.
• Develop and maintain engineering documentation, including P&IDs, system schematics, drawings, and Interface Control Documents (ICDs).
• Ensure compliance with regulatory and safety frameworks, including DO-160, DO-178, DO-254, EASA/CAA requirements, and applicable industrial standards (PSSR, PED, ASME B31.3).
• Apply and promote best practices in hazardous area operations (ATEX, DSEAR) and hydrogen safety, supporting certification and airworthiness activities.

Job Requirements:

• Degree or equivalent qualification/experience in Mechanical Engineering, or a related discipline.
• Strong expertise in gas system design and operation, including compressed gas and hydrogen systems, supported by practical experience in high-hazard environments.
• Proven experience in the specification, integration, and testing of hydrogen fuel systems, including both gaseous and cryogenic storage and supply solutions.
• Solid background in mechanical assembly, pressure testing, leak detection (including helium leak testing), and validation of fluid systems, including knowledge of vacuum systems and outgassing assessment.
• Good understanding of cryogenic systems and hydrogen safety, including risks related to asphyxiation, flammability, and explosive atmospheres (ATEX/DSEAR).
• Knowledge of thermodynamics, fluid dynamics, and gas dynamics, applied to hydrogen system design and performance analysis.
• Experience applying system safety and reliability methods (e.g. FHA, FTA, FMEA/FMECA, SAR).
• Experience with engineering analysis and simulation tools (e.g. ANSYS, MATLAB/Simulink, Python).
• Working knowledge of CAD tools (e.g. SolidWorks) for system design and packaging.

Advantageous:

• Experience developing hydrogen systems for aerospace or other transport applications (automotive, rail, marine), including system layout and integration.
• Understanding of fuel cells and hydrogen propulsion systems, including integration considerations for transport applications.
• Familiarity with aerospace certification, airworthiness requirements, and standards.
• Thermal modelling simulation and analysis experience developing and executing 1D/3D computational models (e.g., CFD, transient thermal analysis) to predict system performance.
