Job description

We are looking for a manual lathe machinist. Much of our manual turning is one‑off: shafts, bushings, sleeves, and pins for repairs, tooling and fixture components, prototypes, and modifications to existing parts, often from a sketch or a worn sample rather than a full drawing.

You will plan each job, set it up, and see it through to a good part, working alongside our CNC machinists and design team.

What you will do

Manual turning

• Set up and operate manual engine lathes.
• Plan the machining sequence, workholding, and tooling from drawings, sketches, or sample parts.
• Hold work in 3- and 4-jaw chucks, collets, and between centres, and indicate it true.
• Turn, face, bore, groove, and cut internal and external threads to drawing tolerances.
• Machine repair parts, modifications, and tooling and fixture components.

Quality

• Measure and inspect work with micrometers, calipers, indicators, and gauges.
• Check diameters, concentricity, threads, and surface finish against the drawing before parts move on.

Shop support

• Support CNC and fabrication jobs with secondary operations such as drilling, tapping, and deburring.
• Perform routine machine maintenance and keep the work area clean and organized.

What you bring

• 3+ years of experience setting up and operating manual lathes.
• Ability to read and interpret technical drawings and blueprints.
• Precision measurement skills using micrometers, calipers, indicators, and gauges.
• Knowledge of cutting tools, materials, and machining techniques for steel, stainless steel, and aluminum.
• Strong mechanical aptitude and the ability to work out a job from a sketch or sample part.

Nice to have

• Surface grinding experience.
• Tool and die, mould, or job-shop background.
• Some CNC operating experience, or interest in learning CNC.
• Russian or Ukrainian language skills.
