Systems Dev Engineer - Environmental Testing, Amazon Leo

About the role

This is a broad scoped position providing manufacturing test ownership of multiple environmental test systems—including TVAC, HASS, and thermal chamber platforms—for the Leo's satellite program.

Responsibilities

• Hands-on experience testing fiber optic/photonic components and RF components or assemblies, with familiarity across both instrument families: optical power meters, optical spectrum analyzers (OSA), and spectrum analyzers, signal generators, and RF power meters.
• Familiarity with the core measurement fundamentals in both domains—insertion loss, return loss, and wavelength stability on the optical side; S-parameters, VSWR, insertion loss, phase stability, and passive intermodulation (PIM) on the RF side—and how these parameters behave across thermal and vacuum environments.
• Experience integrating optical and RF instrumentation into automated environmental test racks, including fiber management and connector inspection standards (e.g., IEC 61300-3-35), RF connector torque and care practices, and calibration/reference verification practices for both measurement types (optical references; VNA cal kits, e-cal, and de-embedding of test cabling).
• Experience with test automation frameworks like TestStand, Robot Framework, or similar tools for creating and managing automated test sequences.
• Ability to read and troubleshoot automated scripts that execute test cases, record results, and handle exceptions.
• Strong debugging skills for identifying issues in test scripts, hardware setups, and measurement paths in both domains—e.g., distinguishing true DUT degradation from connector contamination, fiber stress, or instrument drift on the optical side, and from cable flexure, loose or damaged connectors, thermal drift of test cabling, or stale calibrations on the RF side.
• Familiarity with test equipment error logs, signal analysis, and troubleshooting hardware and software integration problems across electrical, optical, and RF domains.
• Understanding of hardware communication protocols (e.g., SPI, I2C, RS232, Ethernet, GPIB/VISA) to interface with test equipment or devices under test (DUT).
• Proficiency in developing manufacturing process controls to ensure product quality and consistency, including defining key process parameters, implementing statistical process control (SPC) methods, and integrating mistake-proofing (poka-yoke) techniques.

Requirements

Hands-on experience testing fiber optic/photonic components or RF components, including operating relevant instrumentation

Experience working directly with production teams on the shop floor to resolve technical blockers and implement process changes

Qualifications

Experience in development of test plans and protocols related to established Space Hardware test processes (GEVS / SMC-S-016)

2+ years of scripting or programming experience (Python, MATLAB, C, Labview)

Familiarity with optical connector inspection and cleanliness standards (e.g., IEC 61300-3-35) and RF connector care, torque practices, and calibration verification (cal kits, e-cal, de-embedding)

Experience implementing SPC methods and poka-yoke/mistake-proofing in a high-volume manufacturing test environment

Experience qualifying new test equipment and authoring test system documentation for design and process change management
