Senior Manufacturing Engineer, Assembly

Senior Manufacturing Engineer

Amazon is seeking a Senior Manufacturing Engineer to help concept, design, and scale assembly operations. This is a hands-on individual contributor role at a prototyping facility — you'll be designing processes, commissioning equipment, and scaling best practices. The ideal candidate brings 7+ years of experience in high-volume assembly environments, with strong skills in process engineering, equipment deployment, and production system design.

You should be energized by ambiguity, comfortable iterating quickly, and motivated by solving hard problems. This role requires strong technical execution, collaboration across disciplines, and the willingness to roll up your sleeves in a dynamic environment where the next problem is never the same as the last one.

Key job responsibilities include:

• Partner with product design teams to incorporate DFM/DFA considerations, advocate for the simplest and most reliable assembly processes, and iterate rapidly — especially as the product design itself is still evolving.
• Develop and prove out assembly methods — joining, fastening, adhesive bonding, press-fits, human-assisted automation, and robotic assembly — for complex electromechanical products.
• Drive PFMEA considerations upstream in product development. Think of the factory as a fully integrated product — best part/process is no part/process.
• Drive manufacturing line concept, design, requirements, sizing/balancing/timing, material flow, vendor selection, equipment specification, automation strategy, installation, and commissioning.
• Define line requirements including layout, work content, cycle times, rates, and headcount.
• Support detailed design of assembly equipment and fixturing; develop equipment specifications; identify vendors and manage the RFQ, selection, FAT, and deployment process.
• Engage with equipment OEMs, tooling suppliers, automation integrators, and key production partners.
• Drive project scope from concept through production launch.
• Drive production readiness and operational performance, including safety, quality, throughput, and scrap reduction.
• Identify opportunities to densify, 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.
• Apply Lean Manufacturing, Six Sigma, and data-driven problem-solving to drive continuous improvement.
• Mentor junior engineers and contribute to a culture of technical excellence, safety, and operational discipline.
