Why This Role Exists

Bristol Precision continues to grow its prototype and small-batch aerospace, medical, and scientific programs. This Lead CNC Mill Programmer role exists to elevate programming standards, improve machining strategy, and drive consistency across complex 3-, 4-, and 5-axis work.

• Program complex 3-, 4-, and 5-axis CNC milling jobs using Mastercam
• Develop efficient machining strategies and optimize cycle times
• Build complete prototype programs from print to proven process
• Set up and validate first-piece parts as needed
• Create clear, thorough setup documentation for machinists
• Standardize tooling and programming methods to improve repeatability
• Collaborate with setup machinists, production leadership, and quality
• Mentor programmers and machinists on best practices
• Specify material, tooling, and inspection requirements

This role combines high-level programming with hands-on validation and leadership.
