AERODYN ENGINEERING

CNC Machinist/On Machine Programmer

Indianapolis, IN|1st or 2nd Shift|Full-Time

Aerodyn Engineering is looking for a EDM Machinist/On Machine Programmer to machine tight-tolerance, high-complexity aerospace hardware. Most parts held to tolerances as tight as .0005″–.005″, in materials like Hastelloy, Inconel, and 17-4 PH. This is a hands-on role: you'll read the blueprint, write or adjust the program at the machine, set up the tooling, and measure your own work before it moves to the next operation.

• Read blueprints and job routers to hit tight dimensional tolerances on complex aerospace hardware.
• Write and adjust CNC programs at the machine using Mastercam and Solidworks.
• Perform machine setups with a range of tooling — soft/hard jaws, collet chucks, specialty fixtures.
• Machine and deliver high-quality parts in demanding aerospace materials (Hastelloy, Inconel, 17-4 PH, etc.).
• Program feeds, speeds, and depth of cut to match material specs and tooling guidelines.
• Measure finished parts using CMM, calipers, bore gages, pins, and micrometers before handoff.
• Identify and stage tooling ahead of each setup to avoid machine downtime.
• Partner with Manufacturing on troubleshooting, time estimates, and creative fixturing solutions.
• Keep ERP documentation and time entry current for accurate scheduling.

• 3–5+ years of machinist experience in an R&D or low-volume manufacturing environment; aerospace experience strongly preferred.
• Comfortable across conventional and CNC machines, and familiar with welding equipment.
• Solid working knowledge of G & M code programming (Mastercam/NX).
• Strong mechanical aptitude and a knack for creative problem-solving under tight tolerances.
• Self-directed, able to deliver under pressure and hit customer/management deadlines.
• Comfortable working independently as well as part of a team.

• A shop full of experienced machinists and support staff who know this work inside and out.
• Real ownership over your setups — you decide the approach, the tooling, and the process.
• Complex, meaningful aerospace work, not repetitive commodity parts.

• High school diploma required.
• Minimum 3–5 years of machinist experience in an R&D manufacturing environment.
• Aerospace industry experience strongly preferred.
• Knowledge of G & M code programming (Mastercam/NX).
• Strong mechanical aptitude and ability to develop creative solutions to problems.
• Self-directed, professional, and comfortable operating independently and within a team.
• Minimum travel required.
