Why This Role Exists

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

This is not a button-pushing role. You’ll have real influence over how parts are programmed, documented, and executed on the floor.

What You’ll Be Doing

• 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.

• Alloy Steel
• Aerospace and medical-grade materials

What We’re Looking For

Required:

• 8+ years of CNC programming experience using Mastercam
• Experience programming complex prototype parts from start to finish
• Strong understanding of 3-, 4-, and 5-axis milling
• Familiarity with Haas controls
• Ability to inspect your own work to tight tolerances
• Solid understanding of GD&T
• Comfortable working in a small-company, high-accountability environment
• Strong communication skills and professional mindset

Preferred:

• Experience in aerospace, medical, or scientific industries
• Experience mentoring or leading other programmers

  Why Machinists & Programmers Like Working Here
