Sr. Lab Engineer – Photovoltaic Test, Amazon Leo DevOps

• 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
• About the team
• Bachelor's degree or above in Mechanical, Electrical, Industrial Engineering, or related STEM field
• 6+ years of experience operating and maintaining precision lab test equipment in an electrical, electro-optical, or similar high-precision test environment
• Demonstrated experience managing equipment calibration, preventive maintenance, and equipment uptime in a lab setting
• Experience designing and setting up test fixtures and data acquisition setups for complex electrical or electro-optical measurements
• Demonstrated ability to maintain clean, traceable, and well-organized test data and documentation
• Experience troubleshooting complex lab equipment and test setups to root cause
• Experience with photovoltaic or other electro-optical characterization equipment, such as solar simulators, I-V curve tracers, or spectral response/QE systems
• Experience developing measurement uncertainty budgets and calibration procedures, including reference standards, calibration chains, and drift monitoring
• Experience training or mentoring other lab technicians/engineers on equipment and methods
• Experience partnering directly with research scientists or PhD-level engineers to translate research needs into lab execution
• Familiarity with environmental test methods (thermal cycling, thermal vacuum, radiation testing) in an aerospace or R&D context
• Experience leading lab process improvement initiatives (tooling tracking, layout, documentation systems)
