Senior CNC Programmer

Column Technical Services is seeking an experienced Senior CNC Programmer / Master Machinist who can work both independently and collaboratively to machine complex geometries on 5-axis mills and multi-axis lathes. The ideal candidate will have a strong, well-rounded machining background, preferably with experience in the aerospace or turbine industries. Candidates should be highly skilled in advanced CNC machining processes and familiar with modern CAD/CAM systems.

We are looking for someone who is passionate about machining, enthusiastic about new technologies, and motivated to continue developing their technical skill set. This role will focus on the most challenging work in the shop and includes mentoring the next generation of skilled machinists. If this sounds like the right fit for your skills and passion, we encourage you to apply and start a conversation with us.

Please note:

This is a hands-on role involving work from programming to machining through final component completion. It is not a desk-only CAD/CAM position and not a management role.

Key Responsibilities

• Program and machine complex components.
• Use Solid Works or Siemens NX proficiently to design and model parts.
• Program using CAM software (NX Siemens, Esprit, or CAMWorks preferred); support post-processor development and optimization.
• Utilize handheld measuring tools as well as Mitutoyo CMM and/or Faro Arm systems.
• Select appropriate tooling, feeds/speeds, probing routines, and work-holding strategies.
• Support first-article success on tight-tolerance, high-value components.
• Troubleshoot machining issues in real time, including chatter, distortion, thermal growth, and alignment challenges.
• Contribute to prototype, R&D, and low-volume production machining efforts.
• Collaborate with Engineering and Quality teams during early-stage part development.
• Develop setup sheets, tool lists, and documented, proven machining processes.

Job Requirements

Minimum Qualifications

• Minimum of 5+ years of CAD and CAM programming experience for multi-axis lathes and mills.
• Comfortable working full-time both on and off the shop floor, including handling small and large parts safely; must be able to stand, sit, lift, and squat regularly.
• Proven experience programming tight-tolerance components made from difficulty-machine alloys.
• Strong blueprint reading skills with solid GD&T proficiency.
• Experience with fixture design and work-holding solutions.
• Excellent communication, coordination, and organizational skills.
• Ability to lift 50 lbs; experience using cranes, rigging equipment, and forklifts.
