Overview:
Element Digital Engineering is a leading provider of specialist engineering simulation, design, build, test, and consultancy services to clients across the Aerospace, Automotive, Energy, Built Environment, and Chemical Process industries, both in the UK and internationally. We support our clients with design and performance verification, operational troubleshooting, and technical safety assessments using a broad range of approaches — from experienced engineering judgement and hand calculations to advanced simulation, numerical modelling, and physical test.
As part of our continued growth, we are looking for a Fluid Mechanical Assembly Technician to join our team at the Cotswold Airport Hot and Cold Fuel Test Facility — a state-of-the-art, one-of-a-kind site in the UK.
This facility plays a key role in the development and testing of advanced aerospace and propulsion technologies, including liquid hydrogen, hot and cold jet fuel systems, and other fluid mechanical systems under demanding test conditions. Our clients range from global aerospace leaders to cutting-edge start-ups pushing the boundaries of sustainable aviation and propulsion technology.
This role offers a unique opportunity to work hands-on with bespoke, high-performance fluid systems in a fast-paced and highly collaborative R&D environment, supporting some of the most exciting and high-profile developments in the industry today

Responsibilities:

• Build and assemble bespoke fluid mechanical systems from schematics and engineering drawings, including tubular networks, connectors, valves, pressurized gas/liquid systems, and support fixtures
• Interpret and construct systems from minimal or conceptual drawings and translate into practical, test-ready assemblie
• Liaise closely with engineering and test teams to ensure system builds meet specific performance and safety requirements.Install and integrate instrumentation (pressure, temperature, flow, etc.) into mechanical assemblies.
• Conduct functional checks and troubleshoot fluid systems for leaks, pressure integrity, and performance validation.
• Maintain mechanical equipment and ensure readiness of components and tools required for system builds.
• Ensure safe handling of pressurized systems and compliance with internal safety protocols and industry standards.
• Participate in Test Readiness Reviews to ensure system suitability for test.
• Contribute to development of site best working practices, and champion efficient ways of working. Ensure work is carried out in line with relevant HSE best practices and adhering to local risk assessment procedures.
• Contribute to existing site system operations, including operation of facility hydrogen liquefier, jet fuel equipment and other ancillary equipment.
• Be self motivated and able to complete work to a high standard without direct supervision.

Skills / Qualifications:

• Ability to work from schematics, P&IDs, or basic conceptual drawings with minimal supervision
• Proven hands-on experience in the assembly and integration of fluid mechanical systems (tubing, gas/fluid circuits, fittings, etc.).
• Familiarity with pressurized gas and fluid systems, including safety considerations.
• Skilled in using general mechanical tools and equipment for assembly and maintenance tasks.
• Strong communication skills to collaborate effectively with design and engineering teams.
• Attention to detail and a proactive approach to problem-solving during system build and test preparation.
