Senior CNC Machinist

Key Duties & Responsibilities

• Precision Machining Leadership: Lead design and execution on complex component fabrication by independently setting up, programming, operating, and maintaining advanced precision machining equipment, including multi-axis CNC mills and lathes, laser cutters, and high-precision welding equipment
• CNC Programming & Optimization: Drive concept development into reality by developing, editing, and optimizing CNC programs (G-code or CAM software) to maximize efficiency, ensure repeatability, and maintain quality critical for nuclear-grade components
• Quality Assurance & Inspection: Oversee the fabrication process by performing rigorous, high-precision quality control using advanced metrology tools (CMM, gauges) to verify parts meet specified engineering requirements andtight geometric dimensioning and tolerancing (GD&T) standards
• DFM Collaboration: Collaborate daily with engineers and leadership on the company’s most urgent fabrication priorities, providingtechnical insights to streamline designs, improve manufacturability, and accelerate deployment timelines
• Tooling & Fixtures: Design, develop, and implement advancedfixtures, tooling, and manufacturing aids to streamline assembly and test operations for maximum scalability
• Shop Management: Operate autonomously by establishing and enforcing best practices for all shop operations, advanced tool management, preventive maintenance, and strict adherence to safety protocols
• Equipment Expertise: Perform advanced troubleshooting and maintenance on all shop equipment, documenting repairs and coordinating external service when necessary to ensure maximum machine uptime
• Other duties as assigned

Qualifications

• Experience & Education: Minimum8+ years of hands-on mechanical fabrication and precision machining experience, with at least 3 years at a lead or senior level in ahigh-growth, high-urgency environment. Formal apprenticeship or Machinist Certification highly preferred
• Technical Expertise: Deep proficiency inCNC programming (G-code and CAM software), advanced shop mathematics, and complex blueprint reading (including GD&T)
• Prototyping Skill: Proven ability toturn concepts into tested prototypes quickly, managing complex fabrication projects from concept to reality with minimal oversight
• Communication: Exceptionalcommunication and collaboration skills, especially when interfacing with engineers and cross-functional teams on urgent technical challenges
• Drive: Abias toward action, creative problem solving, and the drive toown complex fabrication problems end-to-end in a fast-paced environment
• Advanced CAD/CAM proficiency is required
• Experience advising on material science, machinability, and tool selection for specialized alloys is a plus
• Knowledge of specialized welding (TIG/MIG) is a significant asset
• Previous experience as a Machine Shop Supervisor or Lead CNC Machinist is preferred
