Do you enjoy getting hands-on with complex electromechanical systems and keeping critical test infrastructure running at peak performance? As a Hardware Development Engineer at Amazon, you will combine 3D modeling and mechanical design with the build, maintenance, and troubleshooting of test systems that support hardware production. Working across hardware, software, and production teams, you will diagnose failures, identify root causes, and drive improvements that increase test system reliability and lab operational efficiency. This is a role where your design and engineering skills directly enable the teams around you to ship quality products. Key job responsibilities Design and model hardware components and test fixtures in CAD to meet defined specifications and manufacturing requirements Triage and troubleshoot test system and hardware failures to root cause, using data acquisition systems, power supplies, and safety systems Build, maintain, and repair electromechanical test systems, keeping lab test infrastructure highly available, in partnership with hardware, software, and production teams Develop test stand procedures and training manuals, and automate test systems to improve reliability, lab safety, and efficiency A day in the life You will start your day checking the status of test systems across the lab, prioritizing any failures that need immediate attention. From there, you might open CAD to refine a 3D model for a test fixture, head to the floor to repair an electromechanical assembly. Afternoons could involve reviewing mechanical designs with peers, updating documentation for a modified test stand, or connecting with hardware and software engineers to troubleshoot cross-system issues and plan upcoming infrastructure needs. About the team Our team keeps the test infrastructure running that Amazon's hardware teams depend on to validate and ship products. We own the build-out, maintenance, and continuous improvement of lab systems, partnering closely with hardware, software, and production groups. We value hands-on problem-solving, a commitment to safety, and a collaborative approach to keeping our lab environment reliable and efficient. If you are curious and motivated to improve the systems around you, this is a great place to grow your career at Amazon.
