Sr. Lab Engineer - Photovoltaic Test, Amazon Leo DevOps

Amazon Leo is Amazons low Earth orbit satellite network. Our mission is to deliver fast reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools hospitals businesses and government agencies Amazon Leo will serve people and organizations operating in locations without reliable connectivity.

Were looking for a Sr. Lab Engineer to own the test lab that supports our solar array development team. This isnt a device-physics role its a lab operations role for someone who has spent years running precision test equipment keeping data clean and traceable and being the person a team of scientists and engineers trusts to get a test set up right run it correctly and know when something looks off. Your primary customers will be senior solar scientists. Youll work with them translating their test needs into well-run well-documented lab operations and giving them direct feedback on test setups fixturing and equipment capability.

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.

Key job responsibilities
Own the day-to-day operation of the photovoltaic test lab including equipment calibration schedules preventive maintenance and lab readiness for solar cell and module test campaigns
Partner directly with senior solar scientists to scope test requirements then design and execute the test setups fixturing and data collection methods that meet those requirements
Provide direct technical feedback on proposed test setups and equipment choices drawing on hands-on experience to flag issues before they cost the team time
Manage and prioritize concurrent test requests across multiple scientists and programs communicating status risk and trade-offs clearly
Own data integrity and traceability for all test outputs consistent formatting version control calibration records and documentation that others can pick up and trust
Troubleshoot equipment and test setup issues at the root cause working with vendors when equipment service is required
Develop and maintain test procedures work instructions and lab documentation; train other lab staff on equipment and methods
Drive lab-wide process improvements (layout tooling tracking calibration systems) and mentor other lab engineers

A day in the life
As a Sr. Lab Engineer youll split your time between hands-on equipment operation and coordinating with the scientists who rely on your lab. You might start the morning checking a solar simulators calibration ahead of a test run then sit down with a senior scientist to scope a new test fixture for an upcoming module characterization. Mid-day could involve troubleshooting a data acquisition issue on an environmental chamber or reviewing test data with a colleague to make sure its clean and properly logged before it feeds into someone elses analysis. Youll be the steady hand that keeps test campaigns moving accurately and on schedule even as priorities shift.

About the team
The Amazon Leo Development Operations (DevOps) team supports the Satellite Vehicle Engineering organizations solar array development effort providing the lab infrastructure equipment and test execution that our solar scientists depend on. The team supports multiple concurrent programs spanning production satellites next-generation module development and advanced solar cell R&D.
