Mechanical Design Engineer - Combustor

This is a rare opportunity to join one of Europe’s fastest-scaling engineering startups in Cambridge at a pivotal point in its growth. The company is developing bleeding-edge turbojet technology that will directly impact the aerospace and defence industry, and is now expanding its turbomachinery team. As a Mechanical Design Engineer, you will play a transformational role in the design and development of the engine’s hot section. Working alongside leading engineers in turbomachinery, aerothermal performance and stress analysis, you’ll be trusted with real technical ownership from day one. You will be designing, analysing, testing and iterating hardware that goes straight into engine builds. Your focus will be the combustor, covering sheet-metal design, fabrication methods and development testing. You’ll apply stress FEA to high-temperature components, contribute to the understanding of flow and thermal behaviour in the combustion system, and work closely with manufacturing partners to turn designs into hardware quickly. The environment is fast-moving, technically demanding and deeply collaborative - ideal for an engineer who wants to see their work fly, not sit in review cycles. We’re looking for engineers who have: A strong background in mechanical design (Mechanical or Aerospace degree) Confidence working with CAD (Siemens NX ideal, others considered) An interest or background in combustion systems, hot structures or sheet-metal fabrication Experience or interest in FEA (ANSYS preferred; CFD exposure is a plus)
