Why this job is worth considering

Aerodyn Engineering builds tight-tolerance, first-run aerospace and defense hardware — parts held to tolerances as tight as .0005″–.005″, in materials like Hastelloy, Inconel, and 17-4 PH — for large OEM aerospace customers with exacting quality standards. As a CNC Machinist/On Machine Programmer, you’ll own your setups end to end: reading the blueprint, writing or adjusting the program at the machine, choosing your tooling, and measuring your own work before it moves on. This isn’t repetitive commodity work; it’s complex, meaningful aerospace hardware, built alongside a shop full of experienced machinists who know this work inside and out. Aerodyn is AS9100D & ISO 9001:2015 certified, serving the aerospace and defense industries with engineering, instrumentation, manufacturing, and testing services.

What you'll be doing

• 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 such as Hastelloy, Inconel, and 17-4 PH
• 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

Machines, controls and software

• Comfortable across conventional and CNC machines, with familiarity with welding equipment
• G & M code programming (Mastercam/NX)
• CAM/CAD: Mastercam, Solidworks
• Works in demanding aerospace materials: Hastelloy, Inconel, 17-4 PH

What we're looking for

Required

• 3–5+ years of machinist experience in an R&D or low-volume manufacturing environment
