Job summary

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

Responsibilities include defining tooling and cutting parameters, creating CNC programs, and supporting NPI/FAI while

Qualifications

• Bachelor's degree in Mechanical, Manufacturing, or Industrial Engineering or equivalent hands-on experience.
• 5+ years of process engineering experience specifically in gear, spline, and shaping manufacturing.
• Working knowledge of gear geometry and inspection (involute profile, lead, pitch, runout) and familiarity with AGMA standards.
• Experience with CNC programming or process documentation in a machining environment.
• Understanding of GD&T and ability to read complex aerospace engineering drawings.
• Experience in an AS9100-certified manufacturing environment.
• Strong root-cause/corrective-action and process-capability (Cp/Cpk) skills.
• 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 and specify tooling, fixturing, and cutting parameters for gear shapers, hobbers, and CNC gear-generation equipment
• Troubleshoot process and quality issues on the shop floor (tooth form, lead, profile, runout, surface finish) and drive root-cause corrective action
• Support new part introduction (NPI) and first-article inspection (FAI/AS9102) for new gear and spline programs
• Partner with quality engineering on non-conformances, MRB dispositions, and continuous improvement of AGMA-rated tolerances
• Drive lean manufacturing and continuous improvement initiatives 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
