Sr. Development Lab Test Engineer, Amazon Leo OISL

Amazon Leo is an initiative to launch a constellation of Low Earth Orbit satellites that will deliver low-latency, high-speed broadband connectivity to unserved and underserved communities around the world. Within the Optical Inter-Satellite Link (OISL) organization, you will directly contribute to the development and production of high-bandwidth free-space optical communication systems that connect satellites in orbit.

We are seeking a Development Lab Test Engineer to join our Prototyping and Integration (PI) Team. In this role, you will be the team leader responsible for the execution of environmental and reliability test campaigns for OISL aerospace hardware. You will operate autonomously to drive test campaigns from initiation through closure—owning test execution across thermal, thermal vacuum (TVac), dynamics (vibration and shock), HALT/HASS, and other reliability testing disciplines. You will serve as the subject matter expert on environmental test operations, mentor test technicians, and manage the execution of multiple concurrent test campaigns to ensure hardware is qualified to the highest standards and delivered on schedule.




Key job responsibilities
- Operate as the technical authority on environmental test execution, ensuring all tests are conducted in compliance with test plans, industry standards, and internal work instructions.
- Manage and prioritize multiple concurrent test campaigns, coordinating resources, schedules, and test equipment to maintain program velocity.
- Operate environmental test equipment including thermal chambers, vacuum chambers, vibration tables, and shock tables; oversee test console operations and data acquisition.
- Mentor and lead a team of test technicians, providing technical guidance, training, and oversight to ensure consistent execution quality across all test operations.
- Review test plans from design and systems engineering teams; when needed, translate requirements into detailed execution procedures and work instructions for technicians.
- Generate test reports and capture detailed run notes to aide in post-test data processing.
- Drive continuous improvement of environmental test processes to maximize throughput and enable efficient transition from development testing to production qualification.

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.

A day in the life
You will work hands-on in the lab alongside your technician team—setting up thermal chambers, configuring vibration controllers, reviewing instrumentation, and ensuring every test runs cleanly from start to finish. Between active test executions, you are reviewing incoming test plans, writing procedures, analyzing data from completed campaigns, and coordinating priorities across multiple programs competing for lab resources. When anomalies arise, you lead the investigation. The ideal candidate is equally comfortable at the test console and in a technical review, and brings the kind of operational discipline that gives engineering teams confidence their hardware has been rigorously qualified.
