Location:

Bloomfield, CT

Our client, Liquid Piston, is looking for a Prototype Machinist to support their rapid development and testing initiatives.

About Client:

Liquid Piston is developing advanced rotary engine technologies that redefine what is possible in power generation and propulsion. Our team designs and builds cutting‑edge prototypes that push the boundaries of efficiency, performance, and size.

Position Summary:

The Prototype Machinist will be responsible for machining precision components for engine prototypes and test fixtures. This role requires strong CNC programming and machining experience, exceptional attention to detail, and the ability to work in a fast‑paced R&D environment. The ideal candidate is hands‑on, self‑driven, and comfortable working with both CNC and manual equipment.

• Program, set up, and operate CNC milling machines and lathes, with an emphasis on multi‑axis milling.
• Utilize Haas and Fanuc controls to execute complex machining operations.
• Create and optimize machining programs using Master Cam (preferred).
• Produce high‑precision prototype components from engineering drawings, 3D models, and sketches.
• Inspect parts to ensure dimensional accuracy and quality standards are met.
• Operate manual machine tools, including:
• Surface grinder
• Bridgeport mill
• Manual lathe
• Collaborate closely with engineers, designers, and technicians to refine prototype designs.
• Maintain a safe, clean, and efficient work environment.
• Assist in developing machining processes, tooling selections, and fixture designs for prototype builds.

• Proficiency operating and programming CNC mills and lathes; experience with multi‑axis milling strongly preferred.
• Strong working knowledge of Haas and Fanuc controls.
• Experience programming and tool‑pathing using Master Cam (preferred but not required).
• Demonstrated ability to operate manual machine tools (surface grinder, Bridgeport, manual lathe).
• Ability to read and interpret complex mechanical drawings and GD&T.
• Strong problem‑solving skills and the ability to work independently on prototype projects.
• High attention to detail and commitment to quality.
