Senior CNC Machinist

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.

• 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.

• 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.

• 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
