Alloyed is a young venture-funded company of about 150 world-class metallurgists, engineers, and software developers working across 3 sites in the UK, 1 in Japan, and 1 in Seattle to build the future of advanced metal components. To do this it uses proprietary software packages which combine advanced machine learning and physical modelling to invent better alloys, devise better ways to process them, and design better 3D-printed components.

Alloyed is currently designing a microturbine engine for jet propulsion applications. The system architecture is simple, with outer diameters ranging between 60–240mm considered. The objective of Alloyed’s development programme is to use additive manufacturing to increase performance compared to current state-of-the-art by leveraging more complex designs enabled by additive manufacture and through application of more thermally resistant materials. In parallel, the target is to consolidate the number of parts in the engine, reduce production cost and enable high production rate.

Alloyed is seeking a motivated Mechanical Design Engineer to support the design & prototyping of microturbines across different thrust ranges. This role involves close collaboration with experimental teams to validate and improve designs. You will report to the Design Lead and play a key role in optimizing jet engines.

You will be based at Alloyed’s manufacturing site in Abingdon. A highly competitive remuneration package is offered, including equity incentives.
