CMI Group; Tempe (AZ); On-site; USD 120,000 - 150,000; Full time

Job summary

CMI Group is seeking a Senior Process Engineer to own and advance gear, spline, and shaping manufacturing processes. You will develop and document processes for complex gear components used in aerospace platforms, driving quality, throughput, and cost performance from raw material through final inspection.

You will lead the creation of process documentation, tooling selection, and CNC programs, while troubleshooting on the shop floor and supporting NPI/FAI efforts.

Qualifications

• Bachelor's degree in Mechanical, Manufacturing, or Industrial Engineering (or equivalent hands‑on experience).
• 5+ years of process engineering in gear, spline, and shaping manufacturing.
• Working knowledge of gear geometry and AGMA standards.
• Experience with CNC programming or process documentation in a machining environment.
• Understanding of GD&T and reading complex aerospace drawings.
• Experience in an AS9100‑certified manufacturing environment.
• Direct experience with gear shapers, hobbing machines, or spline rolling equipment.

Responsibilities

• Develop and optimize manufacturing processes for gear shaping, spline rolling/shaping, hobbing, and related gear-form operations on aerospace hardware.
• Create and maintain process documentation: routers, work instructions, setup sheets, and CNC programs in coordination with programming/manufacturing engineering.
• Select tooling, fixturing, and cutting parameters for gear shapers, hobbers, and CNC gear‑generation equipment.
• Troubleshoot process and quality issues on the shop floor and drive root‑cause corrective action.
• Support new part introduction and first‑article inspection for new gear and spline programs.
• Partner with quality engineering on non‑conformances and continuous improvement of AGMA‑rated tolerances.
• Drive lean manufacturing and continuous improvement to reduce cycle time and scrap.
• Collaborate with tooling suppliers, program management, and customer engineering on process capability and DFM feedback.
• Support capital equipment justification and qualification for new gear‑cutting and finishing technology.
