Job description

We are looking for a manual machinist who is comfortable on both the mill and the lathe. Much of our manual work is one-off: repair parts, 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 machining

• Set up and operate manual lathes, milling machines, and drill presses.
• Plan the machining sequence, workholding, and tooling from drawings, sketches, or sample parts.
• Turn, face, bore, thread, mill, drill, and tap parts to drawing tolerances.
• Machine repair parts, modifications, and tooling and fixture components.

Quality

• Measure and inspect work with micrometers, calipers, indicators, and gauges.
• Check parts against drawing tolerances and surface finish requirements before they 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 and milling machines.
• 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.
