Senior Prototype Machinist

The Exploration Company develops, manufactures, and operates Nyx, a modular, reusable orbital spacecraft designed to be refuelled in orbit and transport cargo, with crewed missions potentially planned for the longer term. The role is to take full ownership of the machining process for space-grade components, including CAM programming, machine setup and optimisation, and continuous improvement, while contributing to future investments in machining equipment and tooling. The work covers high-precision parts such as rocket engine components, post-processed metal 3D-printed parts, and critical propulsion subcomponents, across a fleet of multi-brand 5-axis machining centres and CNC lathes. Fluency in English is expected.
