Description
Amazon is seeking a Principal Gear & Gearbox Manufacturing Engineer to serve as our technical authority for precision gear and gearbox manufacturing across advanced electromechanical systems. You will own gear manufacturing strategy end-to-end - cutting, grinding, heat treatment, finishing, and assembly - with deep expertise in the interplay between micro-geometry, material behavior, and NVH performance for precision actuators. You will define our technical standards, drive supplier and equipment decisions, shape product architecture for manufacturability, and lead our gear manufacturing engineering discipline. This role requires someone with mastery of precision gear production, established industry relationships, and the ability to
operate as both a hands-on technical expert and a strategic manufacturing leader.
Key job responsibilities
Technical Authority & Engineering Leadership
Serve as principal technical authority on all gear manufacturing decisions from material selection through final quality verification
Own end-to-end gear and gearbox manufacturing strategy: gear cutting (hobbing, shaping, skiving), grinding, heat treatment, finishing (lapping, honing, superfinishing), and gearbox assembly
Define manufacturing standards and identify capability requirements.
Set technical standards and best practices for the gear manufacturing team
Supplier Ecosystem & Industry Partnerships
Establish strategic partnerships with gear machine tool OEMs, cutting tool suppliers, heat treatment providers, metrology equipment vendors, and contract gear manufacturers
Drive supplier selection, qualification, and performance management
Negotiate technical requirements, capacity commitments, and quality standards with supplier leadership
Production Engineering & Process Development
Own gear manufacturing portion of production facility design: equipment selection, process flow, thermal management, automation strategy, and layout
Define specifications and lead procurement of gear hobbing/grinding machines, heat treatment furnaces, metrology systems, and assembly equipment
Manage supplier partnerships and production sourcing strategy
Design Influence & Cross-Functional Leadership
Partner with hardware engineering from concept through production on DFM/DFA specific to gears (macro/micro geometry, tooth modifications,
material selection, tolerance stack-ups, cost tradeoffs)
Influence product architecture for manufacturability, gear quality grade, NVH performance, and supply chain resilience
Establish design guidelines and manufacturing constraints that enable scalable product development
Process Development & Technical Problem Solving
Drive process development and optimization for precision actuator gears: cutting parameters, heat treatment profiles, grinding strategies, finishing sequences
Solve critical manufacturing challenges - distortion control, surface integrity, micro-geometry compliance, NVH root cause analysis
Establish process parameters, inspection criteria, and quality control methods for high-precision gears (AGMA/DIN quality grades)
Manage multi-supplier gear manufacturing programs from concept through production
Create process specifications, PFMEA, control plans, and manufacturing standards
Basic Qualifications
Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Materials Science, or related field
10+ years in precision gear and/or gearbox manufacturing engineering in production environments (automotive, aerospace, precision electromechanical, power transmission, or similar)
Track record as a technical leader solving complex gear manufacturing problems and driving engineering excellence
Deep expertise across gear cutting, heat treatment metallurgy, finishing operations, and gear metrology
Experience building strategic supplier relationships at engineering leadership levels
Experience influencing product design through DFM/DFA and cross-functional collaboration
Strong background in equipment selection and manufacturing process optimization
Ability to lead technical initiatives across multiple organizations without direct authority
Experience with CAD software and gear design/analysis tools (KISSsoft, ROMAX, or similar)
Expert knowledge of GD&T, gear metrology (profile, lead, pitch, runout), and SPC
Preferred Qualifications
Master's degree or PhD in Mechanical Engineering, Manufacturing Engineering, or related field
Experience across multiple gear @types (spur, helical, bevel, worm, planetary/epicyclic, harmonic/strain wave)
Deep expertise in gear NVH and the relationship between manufacturing process, micro-geometry, and noise performance
Familiarity with powder metallurgy gears, gear skiving, hard finishing, or additive manufacturing for tooling
AGMA membership, committee involvement, or conference participation
Knowledge of gear standards (AGMA, ISO 1328, DIN 3960 series)
Experience with heat treatment process control (carburizing, nitriding, induction hardening) and distortion management
Published research, patents, or recognized industry contributions in gear manufacturing
