Description

Amazon is seeking a Principal Manufacturing Engineer to define and drive the manufacturing strategy manufacturing strategy for new product introductions, informing production line design while partnering to design the product for manufacturing. This is a senior technical leadership role — you'll create clarity from ambiguity, set manufacturing direction and architect production systems that maximize learning velocity while laying the groundwork for future high-volume scale.

Description

Amazon is seeking a Principal Manufacturing Engineer to define and drive the manufacturing strategy manufacturing strategy for new product introductions, informing production line design while partnering to design the product for manufacturing. This is a senior technical leadership role — you'll create clarity from ambiguity, set manufacturing direction and architect production systems that maximize learning velocity while laying the groundwork for future high-volume scale.

The ideal candidate brings 10+ years of experience spanning both high-volume assembly environments and rapid prototyping / NPI operations for complex electromechanical products. You should have a track record of standing up build operations from scratch, driving process development roadmaps, and influencing product architecture decisions — not just providing DFM feedback. This role requires strategic thinking, deep technical credibility, the ability to align cross-functionally, and the willingness to roll up your sleeves in an environment where requirements evolve quickly.

Key job responsibilities

• Serve as the manufacturing voice in daily design trades — influence product architecture, tolerance strategy, and material selection in real time. Advocate for the simplest and most reliable assembly processes, and drive DFM/DFA considerations upstream as a co-designer as the product design itself is still evolving.
• Define the end-to-end manufacturing strategy across build iterations: process architecture and the transition path from prototype to volume production.
• Create clarity from ambiguity: establish frameworks, standards, and decision criteria that guide the broader engineering team. Define what “ready to build” means at each stage and own the manufacturing readiness process.
• Develop and prove out assembly methods (joining, fastening, adhesive bonding, press-fits, human-assisted automation) with an emphasis on rapid iteration and reconfigurability between builds. Determine direction by thoughtful balance between operational efficiency for faster learning cycles.
• Define build instrumentation and data capture strategies to maximize learning per build cycle. Translate build observations into actionable design and process feedback. Own the build report / lessons-learned process that feeds the next design iteration.
• Drive manufacturing line concept, design, requirements, material flow, vendor selection, equipment specification and commissioning.
• Design quick-turn fixtures and tooling; make smart build-vs-buy decisions on tooling — knowing when 80% is good enough to learn. Leverage rapid prototyping methods (3D printing, laser cutting, modular framing) for process tooling.
• Engage with equipment OEMs, tooling suppliers, automation integrators, and key production partners.
• Identify opportunities to reduce non-value-add operations and drive significant improvements from one build iteration to the next.
• Develop and standardize assembly processes, control plans, maintenance strategies, and operational documentation appropriate to build maturity level.
• Mentor engineers and contribute to a culture of technical excellence, safety, and operational discipline. Raise the bar on hiring, develop the team's technical capabilities, and shape the engineering culture.

Basic Qualifications

• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Industrial Engineering, or equivalent technical discipline.
• 10+ years of direct manufacturing engineering experience, including high-volume assembly environments and prototyping / NPI / low-rate initial production for complex electromechanical products.
• Experience owning manufacturing strategy for a new product introduction (NPI) from concept through volume production.
• Experience supporting commissioning, startup, and ramp-up of integrated assembly operations.
• Strong knowledge of assembly methods including mechanical joining, fastening, adhesive bonding, press-fits, human-assisted automation, and robotic assembly.
• Demonstrated ability to create clarity from ambiguity — defining strategy and decision criteria for cross-functional teams.
• Ability to influence at a senior level across engineering, product design, and program leadership.

Preferred Qualifications

• Experience working with interdisciplinary teams to execute product design from concept to production
• Experience with build instrumentation, data capture, and structured lessons-learned processes in prototype or development builds
• Experience with rapid prototyping methods for process tooling (3D printing, laser cutting, modular framing)
• Experience in R&D, skunkworks, or advanced development environments
• Master’s degree in Mechanical Engineering, Manufacturing Engineering, or equivalent
• Experience with the project management of technical programs at a portfolio level
