MTrec’s new career opportunity Our client are specialists in their market sector, they are looking for an experienced Senior CNC Machinist to join an established team. The Job you’ll do * We are seeking a highly skilled CNC machinist to join our in-house engineering department, working at the forefront of classic engine development and restoration. * This role is centred around the machining and development of engine components — including raw cylinder head castings, engine blocks, and bespoke performance parts — supporting both restoration and our ongoing engineering programmes. * CNC machining of raw and semi-finished cylinder heads and engine blocks. * Programming, setting and operating our Doosan CNC machinery. * Machining one-off and small batch precision components. * Working from CAD models, engineering drawings, and in some cases, developing machining strategies from first principles. * Supporting R&D projects, including our uprated engine programmes. * Inspection and quality control of machined components. * Collaborating closely with engine builders and design engineers. * This is not a production environment. Every project is approached with care, accuracy, and an emphasis on quality over volume. * Opportunities to join the team are rare and reserved for individuals who take genuine pride in their work and can appreciate a key part of the role is the opportunity to see your work through from raw material to finished component, and ultimately into a running engine. * There is a real satisfaction in knowing that the parts you machine go on to power some of the most iconic cars, rather than disappearing into a production line. * You will be working as part of a small, highly skilled team on projects that demand both precision and thought, where your input genuinely matters. * This role offers the opportunity to expand beyond machining into wider engine development work, including: * Exposure to engine remanufacturing and assembly processes. * Involvement in cylinder head flow bench development and testing. * Working closely alongside highly skilled engineers and engine builders, with the opportunity to develop a broader understanding of engine performance and design. * This is a role for someone who wants to deepen their engineering capability, not remain confined to a production-style machining position. About You * A strong track record in CNC machining within a precision engineering environment is essential. * Strong experience in CNC machining (3/4/5 axis preferred). * Proven ability to machine complex aluminium castings (ideally cylinder heads or similar). * Experience working to tight tolerances on high-value components. * Confidence in programming (Fusion 360, Hypermill, or similar CAM software advantageous). * A methodical, detail-driven approach with a strong sense of ownership. * Ability to think beyond drawings and contribute to machining strategy. * Experience machining engine components (cylinder heads, blocks, crankcases). * Motorsport, aerospace, or high-performance engineering background. * Understanding of fixturing complex castings. * Interest in classic or high-performance engines. The Rewards and the Benefits Involvement in cutting-edge development projects alongside heritage restoration. A clean, well-equipped, and forward-thinking engineering environment. Competitive salary based on experience. Long-term career opportunity within a respected specialist business. Company pension. Free parking. On-site parking
