Strong electrical fundamentals and ability to read schematics and debug circuits. * You can write useful test automation. Experience with oscilloscopes, power analyzers, electronic loads, DAQs, and bench instrumentation. * You are comfortable with lab equipment. Python proficiency for automation, analysis, and instrument control. * You can debug across disciplines. Experience building test fixtures and repeatable validation processes. * You know how to build repeatable tests. Ability to distinguish hardware, firmware, communications, and system-level failure modes. * You own problems through resolution. Strong experimental rigor, documentation, and ownership. Preferred skills * Experience with DC-DC converters, solar, batteries, or embedded controllers. * Familiarity with environmental chambers and accelerated reliability testing. * Experience with SCPI, LabVIEW, CAN, UART, SPI, or similar interfaces. * Experience building production test equipment and dashboards. Additional requirements * Willingness to work extended hours as needed to support critical milestones * Everyone at Optivolt is required to participate in on call support for customers * Must be based in San Francisco, CA ## Description * Build test systems that engineers rely on. Design and maintain test benches for Hub, power electronics, and integrated solar systems. * Automate repetitive validation work. Develop automated test scripts, fixtures, instrumentation interfaces, and data collection systems. * Measure what matters. Characterize electrical performance, efficiency, communications, thermal behavior, and protection functions. * Find the edge cases early. Run functional, environmental, stress, and firmware/hardware regression testing. * Make failures reproducible. Build hardware-in-the-loop or other automated system validation where useful. * Turn measurements into answers. Analyze data, reproduce failures, isolate root causes, and partner with engineers on fixes. * Work across hardware and firmware. Write repeatable test plans, acceptance criteria, procedures, and concise reports. * Bring validation into production. Support certification testing, outdoor trials, and end-of-line manufacturing test.
