- Independently mill and deliver company critical components across a wide range of CNC platforms including 3-axis, 5-axis, and mill/turn centers, setting the benchmark for precision, speed, and workmanship.
- Write, debug, and optimize CAM programs and toolpaths for challenging geometries and tight tolerances, and establish best practices that are adopted consistently by the team.
- Plan, prioritize, and protect daily machining schedules by balancing machine capacity and program urgency in a dynamic R&D environment.
- Serve as the primary manufacturing interface for engineering during the shift by providing real time feedback on risk, schedule, and design for manufacturability based on direct machining experience.
- Ensure clean handoffs and operational continuity across shifts through disciplined documentation, communication, and coordination with other shift leads.
- Lead and develop a team of machinists by setting clear expectations, defining daily and longer term goals, and maintaining consistent, transparent communication.
- Foster a collaborative, high trust shop environment where machinists are supported, informed, and empowered to execute high quality work.
- Conduct regular performance check ins, provide actionable technical and behavioral feedback, and remove systemic blockers that limit productivity or quality.
- Hold the team accountable for safety, quality, and workmanship while modeling professionalism, technical rigor, and calm decision making under pressure.
- Train and mentor machinists and technicians through hands-on instruction in machining fundamentals, advanced CAM workflows, GD&T, and metrology techniques.
- Support career growth and skill progression while reinforcing a culture of precision, ownership, safety, and continuous learning.
- Own shift level tooling and material readiness, including procurement and inventory decisions that support uninterrupted production.
- Monitor machine performance, identify reliability risks, and coordinate with facilities and equipment teams to minimize downtime and protect capacity.
What You Will Need
- Five or more years of hands-on CNC machining experience in prototype or research and development environments, with deep expertise in milling high precision parts.
- Demonstrated expert level hands on experience machining high precision parts in prototype or research and development environments, including advanced 5 axis and mill/turn platforms.
- Demonstrated expert level proficiency in CNC milling across 3-axis and 5-axis platforms, with experience on mill/turn centers.
- Deep mastery of at least one modern CAM system (Fusion preferred) with the ability to personally program complex parts and coach others on efficient, robust workflows.
- Advanced literacy in GD&T with proven ability to interpret complex prints, hold sub thousandth tolerances, and identify manufacturability risks.
- Strong proficiency in inspection and metrology, including experience with CMMs and in process inspection techniques.
- Proven capability designing fixtures and tooling for complex, high mix work, including scalable and repeatable workholding solutions.
- Demonstrated ability to manage multiple competing priorities, adapt plans as designs evolve, and maintain quality under schedule pressure.
- Commitment to safety, professionalism, and compliance with all required PPE and shop practices.
- Prior experience leading, mentoring, or coordinating machinists or technicians in a production or R&D environment.
- Physical readiness to stand for long periods, lift 50 pounds, wear required PPE, and follow all company safety regulations.
