Senior Mill-Turn Machinist

Kairos Power is a new nuclear energy technology and engineering company whose mission is to enable the world’s transition to clean energy, with the ultimate goal to dramatically improve people’s quality of life while protecting the environment. This goal will be accomplished through the commercialization of the fluoride-salt-cooled, high‑temperature reactor (FHR) that can be deployed with robust safety, affordable costs, and flexible operation to accommodate the expansion of variable renewables.

Job Summary

Kairos Power is seeking a highly skilled and motivated Senior Mill‑Turn Machinist experienced with multitask machining operations, including dual spindle lathes or mill‑turn machines. In this role, you will support precision machining operations of a wide range of component sizes requiring tight tolerances and complex geometry. The Senior Machinist will contribute to Kairos Power’s machining capabilities by operating a variety of multi‑axis machines to create quality parts that meet all engineering specifications with exceptional craftsmanship.

This position supports the execution of manufacturing processes that support the company’s Fluoride Salt‑Cooled High‑Temperature Reactor (FHR) program and broader technology initiatives.

• Interprets blueprints and 3D models to develop NC programs, design fixturing, plan machining sequences, and operate CNC machines to produce precision components.
• Multi‑axis programming with industry software such as Master Cam.
• Creates safe work holding methods and plans for work coordinates or tooling before any machine operations.
• Set up, operation and programming of a wide range of component sizes to deliver parts on internal deadlines and quality requirements.
• Operate shop‑related machines and equipment such as band saws, hand tools, and measuring equipment while preparing material.
• Select appropriate jaws or create custom work holding using primarily hydraulic chucks on main and sub spindles in mill‑turn machines.
• Monitor machine operations and interpret G and M codes to verify accuracy of machined work pieces to specifications; make adjustments as needed.
• Maintain a clean and organized work environment, keeping paperwork organized to prevent loss of stock or tooling.
• Identify and resolve machining challenges independently and assist others as needed.
• Execute rigging, material movement and setup of large (over 1,000 lb) machined parts following established safety protocols.
• Perform precision machining operations on parts and components within multi‑process assemblies, including components that have undergone prior processes such as welding, rolling, and forming.
• Maintain compliance with internal quality standards and proficiently utilize job scheduling software to track production and shop‑floor operations.
• Complete and maintain accurate job travelers and first‑article inspection reports to ensure documentation compliance and traceability.
• Other duties as assigned.

• High school diploma or GED required, along with 5+ years of relevant machining experience (mill, lathe, 3‑axis, 5‑axis, live‑tooling) or an equivalent combination of education, training, and hands‑on experience.
• Experience in rigging, material movement and setup of large machined parts and supporting lift plans.
• Experience in reading and interpreting engineering and assembly drawings.
• Experience with a mill‑turn environment in Master Cam a plus.
• Experience with live centers or steady rests on long parts a plus.
• Experience with Okuma Multus, DMG Mori NTX or Mazak Integrex.
• Familiarity with Solid Works or similar CAD platforms to assist with understanding part geometry and communicating with engineering teams is a plus.
• Proficient programming with CAM software (Master Cam preferred).

• Knowledge of CAM‑CAD software and G‑code.
• Ability to adapt machining processes and operation between different jobs and complexities of parts.
• Understanding of basic and advanced GD&T: tolerancing, flatness, parallelism, thread tolerances, profile tolerances, perpendicularity.
• Knowledge of CNC cutting tool selections, tool surface footage, and chip‑load feed rates.
• Ability to work with shop…
