Senior Prototype Machinist
About this role
Here at The Exploration Company, we are building spacecrafts for humanity. [ Deutsche Version weiter unten] Your Mission At The Exploration Company, we develop, manufacture, and operate Nyx — a modular, reusable orbital spacecraft designed to be refuelled in orbit and transport cargo, with crewed missions potentially planned for the longer term. We’re looking for a hands-on, technically mature professional with an engineering degree or extensive CNC experience to take full ownership of the machining process for space-grade components.
You’ll be responsible for CAM programming, machine setup and optimisation, and continuous improvement. You’ll also contribute directly to future investments in machining equipment and tooling. You’ll work on a variety of high-precision parts, including rocket engine components, post-processed metal 3D-printed parts, and critical propulsion subcomponents. You’ll work across a fleet of modern, multi-brand, 5-axis machining centres and CNC lathes.
This role offers a high-impact technical position, with opportunities for career growth and increased responsibility. Fluency in English is expected, as our work environment is international. Your Responsibilities Define and optimise machining strategies, including sequencing, tooling, fixtures, and in-process controls. Program complex components in HyperMill or equivalent CAM software for 5-axis milling and CNC turning.
Validate parts using multi-brand CNC equipment, ensuring that they meet tolerance and surface-finish requirements. Manufacture rocket engine components, precision assemblies, propulsion subcomponents, and Inconel structures, including setting workpiece origins and preparing cutting tools. Perform first-line maintenance to keep machines in good working order. Analyse and improve toolpaths, reduce cycle times, and stabilise machining quality.
Work with design, quality, and production teams to provide feedback, propose design improvements, and troubleshoot issues. Lead equipment investment efforts, including specification development, supplier coordination, and commissioning. Profile An engineering degree or 5+ years of experience as a highly skilled technician in CNC/CAM machining of complex parts. Expertise in HyperMill or equivalent CAM software and tight-tolerance machining.
