A UK aerospace start-up developing a new class of lightweight, electrically powered aircraft is growing its internal structures capability and is now looking for a Composites Design Engineer to join the team. This is a hands-on role within a small, talented engineering group working across concept development, detailed design, analysis and build support. You’ll have the chance to influence key structural decisions on a novel aircraft platform and see your work progress quickly into test and development. The Opportunity You’ll own composite component design from first principles through to production-ready detail, using Siemens NX for modelling and contributing directly to structural analysis, optimisation and documentation. You’ll also work closely with suppliers and manufacturing partners to ensure designs align with real-world processes. The role suits someone who is comfortable balancing design creativity with practical engineering judgement – and who enjoys working in a fast-moving, collaborative environment. Responsibilities Designing composite airframe and aerostructure components in NX Performing analysis and sizing of composite structures (classical methods laminate evaluation) Producing drawings, material definitions, reports and release documentation Supporting manufacturing, tooling and structural test activities Helping establish internal standards and best practice for composite design Working with systems, aerodynamics and manufacturing teams to ensure seamless integration across the aircraft About You We’re looking for a competent Composites Design Engineer with strong aerospace experience and a solid understanding of both composite design and analysis. You’ll Bring: Strong CAD capability in Siemens NX Experience designing composite structures for airframes or aerostructures Ability to assess loads, define laminates and evaluate structural performance Awareness of composite manufacturing processes and their design implications Clear communication skills and a methodical engineering approach A relevant engineering degree or equivalent experience Experience with FEA tools, flight test support or structural test correlation is helpful but not essential. Why this role? Work on a cutting-edge lightweight electric aircraft programme See your designs move rapidly from concept to build and test Be part of a tight-knit engineering team where your impact is immediate Enjoy variety, autonomy and visibility in a growing organisation If you’re interested in contributing to one of the UK’s most exciting developments in advanced air mobility, I’d be happy to share more details.
