Environmental Test Engineer, Amazon Leo

Amazon Leo is building a low Earth orbit satellite constellation to deliver fast, reliable broadband to customers and communities everywhere - including the places the internet has never reliably reached. Every satellite we launch is qualified in our Space Simulation Lab at SEA133. If flight hardware is going to survive launch, vacuum, thermal cycling, and years on orbit, it has to prove it to us first.

Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

As an Environmental Test Engineer on the SSL team, you won"t be one of many engineers maintaining a shared pool of equipment. You"ll be the primary owner of an entire class of test equipment - Thermal, TVAC, Vibe, Shock, or HASS - accountable for keeping it running, driving its reliability upward, and building the processes that let the lab test at launch cadence. When something goes wrong at 2 AM, your name is on the escalation. When something needs to change, you own the engineering decision and the vendor conversation. When a technician learns the equipment, they learn it from you.

This is a build job, not a maintain job. We"re scaling SSL fast and we need an engineer who looks at tribal knowledge and turns it into standard work; who looks at a vendor"s response time and decides it"s not good enough; who can read a thermal ramp trace or a shaker response curve and tell you whether it"s a tuning problem, a hardware problem, or a software problem. You will have autonomy, a direct line to leadership, and a tangible connection between the work you do this week and the hardware that leaves Earth next quarter.

If you want your engineering decisions to show up in orbit - not just in a dashboard - come build this with us.

Key job responsibilities

Equipment Ownership

• Serve as primary owner for an assigned class of environmental test equipment (Thermal, TVAC, Vibe, Shock, or HASS), managing configurations, maintenance, calibration, and improvement projects.
• Provide technical leadership during troubleshooting events, driving issues from first response through root cause and corrective action.
• Manage relationships with 3rd-party equipment vendors (service, spares, upgrades, escalations).

Process Development

• Establish standardized test processes and work instructions that enable technicians to operate with minimal engineer supervision.
• Train and mentor technicians on equipment operation and troubleshooting; keep documentation accurate and current.

Rate Improvement

• Analyze test data to validate ability of test procedures to meet requirements.
• Identify and lead projects that increase throughput, reduce cycle time, and improve first-pass yield.

Automation Troubleshooting

• Read and triage simple errors in LabVIEW and Python code execution; clearly articulate failures to support teams for more complex issues.
• Apply understanding of control loops used in environmental test (thermal ramp control, vacuum/pressure control, shaker control) to diagnose equipment behavior.
