About this role
Kairos Power, a advanced nuclear reactor developer, seeks a Machinist III to design, program, and operate precision multi-axis machine tools (lathes, mills, boring machines, grinders) for manufacturing critical nuclear reactor components and assemblies. You'll interpret engineering blueprints, develop NC programs, perform in-process quality inspections, and ensure all machined parts meet strict nuclear industry tolerances and specifications.
Responsibilities
- Read engineering blueprints and job orders to determine product specifications, dimensions, tolerances, tooling instructions, and sequence of operations
- Establish work coordinate systems and tooling offsets for multi-axis machines
- Create work holding methods and plans for all machine operations
- Position and secure workpieces in holding devices, machine tables, chucks, centers, or fixtures
- Set up and operate CNC machines (mills, lathes, boring machines, grinders) with 3-axis, 5-axis, and live-tooling capabilities
- Monitor machine operations and verify conformance of machined workpieces to specifications using precision measuring tools
- Create and edit NC programs using CAM software (MasterCam)
- Maintain compliance with internal quality standards and nuclear-grade documentation requirements
- Complete and maintain accurate job travelers, first article inspection reports, and quality documentation
Preferred qualifications
- Experience with Solidworks or equivalent CAD software
- Forklift and boom lift certification
- Prior experience in nuclear, aerospace, or highly regulated manufacturing sectors
Location, schedule, and travel
Onsite in Richmond, CA and Alameda, CA (headquarters). Schedule includes occasional 2nd shift (4:30pm start), overtime, and weekend work with flexibility required. Physical demands: standing/sitting for prolonged periods, moving objects up to 25 lbs, operating machinery and hand tools in a noisy environment with potential chemical odors/fumes. Required PPE: face mask, face shields, gloves, safety shoes.
