Electro-Mechanical Prototype Engineer — Space Hardware Lab

Socket.dev; Los Angeles (CA); On-site; USD 54,000 - 95,000; Full time

Job summary

Amazon in Northridge, CA seeks an Electro-Mechanical Prototype Engineer to join the Prototyping & Integration Team. You will build prototype wire harnesses and PCB assemblies from schematics, solder and validate hardware for rapid iteration.

The role is primarily lab-focused—fabrication, harness routing docs, BOMs, process docs, and hardware procurement coordination—requiring meticulous, autonomous lab work in a clean, ESD-controlled environment.

Qualifications

• Experience using common electronics test equipment (oscilloscopes, power supplies, function generators, etc)
• Experience reading and writing procedures, technical documents, and engineering drawings, or experience in electrical or mechanical engineering
• Associate's degree or equivalent in Electronics, Electrical Technology, Manufacturing Technology, or related STEM discipline; or 5+ years of equivalent hands-on experience.
• 5+ years of hands-on experience building wire harnesses and electro-mechanical assemblies—including soldering and PCB rework (through-hole and surface mount)—by reading and interpreting electrical schematics, wiring diagrams, and mechanical drawings.
• Demonstrated ability to work autonomously in a lab or prototype shop environment following ESD protocols.
• Must be able to perform fine motor tasks—soldering, pinning, and harnessing—and visually inspect and distinguish fine detail in precision electro-mechanical components, with or without reasonable accommodation.

Responsibilities

• Execute prototype harness builds and electro-mechanical assemblies from engineering schematics, wiring diagrams, and mechanical drawings—including mil-spec connector crimping and pinning—to workmanship and traceability standards.
• Perform PCB soldering, rework, and inspection (through-hole and surface mount) using hand soldering stations and associated tools.
• Generate and maintain Bills of Materials (BOMs); identify, source, and procure required hardware and components.
• Operate hand tools, DVMs, hi-pot testers, and Rapid Harness software to execute and validate builds.
• Create and maintain technical documentation—harness schematics, routing drawings, system-level diagrams, work instructions, and assembly notes—for repeatable prototype and low-rate production builds.
• Communicate build status, issues, and blockers to engineers and team leads, escalating in a timely manner while maintaining a safe, clean, ESD-controlled lab.
