Reliability Engineer - Photovoltaics

About the role

At Swift Solar, our mission is to unlock the full potential of solar energy. We believe solar can provide affordable, reliable, resilient, clean energy to virtually anyone, anywhere . But while today's solar technology is good, it's not good enough. Swift Solar 's breakthrough perovskite-silicon tandem technology will drive solar power to commanding new heights . Our tandem cells stack a perovskite layer on top of a heterojunction (HJT) silicon cell, delivering dramatically higher efficiency than traditional silicon alone. In 2026, we acquired Meyer Burger's HJT intellectual property and manufacturing assets, giving us the world's most extensive HJT patent portfolio and a clear path to gigawatt-scale domestic production. This vertically integrated approach means we can design, manufacture, and scale next-generation solar solutions entirely in the United States-from silicon foundations to perovskite innovations. Our technology enables applications ranging from space solar to utility-scale power generation, creating American-made solutions for a world facing growing energy challenges . Swift Solar is on a journey to bring revolutionary clean-energy technology to market. We're in it for the long haul, with support from world-class investors . Join our extraordinary team building the cutting-edge solar technology that will power the future. A day in the life As a Reliability Engineer at Swift, you'll drive cell-package interactions and module-level reliability, addressing the unique challenges of a first-generation technology moving from concept through certification and towards manufacturing. On a typical day, you might schedule and execute reliability tests on tandem mini-modules and full modules-spanning environmental, thermomechanical, and accelerated life tests such as damp heat, thermal cycling, UV, and outdoor exposure-then evaluate the results. You might perform failure analysis on tandem modules, design a non-standard accelerated stress protocol to reproduce a field failure, or coordinate third-party testing with external labs. You'll contribute a reliability perspective, collaborate with the Product Management team on lifetime modeling, and develop hypotheses you communicate clearly to the Materials R&D, Process Engineering, and Product Development teams. As an early hire, you'll help shape how the reliability function operates as the team grows and interacts with every part of the company along the way. You might be a good fit if you... Have 3-5 years of experience in PV module reliability, spanning from R&D to third-party validation and certification. Have a demonstrated ability to diagnose failure mechanisms and translate findings into data-driven insights for cross-functional teams. Have experience working with external testing labs to define and complete testing. Have a solid understanding of PV cell and module device physics. Have a proven ability to work well with cross-functional teams (R&D, Product Development, Engineering, Manufacturing), showing strong communication and empathy. Are proficient in statistical analysis software (e.g., JMP) and the application of statistics to reliability analysis. A strong candidate might bring one or more of the following... Experience with more than one PV cell type. Experience developing non-standard accelerated testing protocols for a first-generation technology. Familiarity with reliability engineering tools (e.g., FMEA, 8D, RCA, DFR). Experience sourcing reliability test equipment. An understanding of why solving climate change is an urgent and critical challenge. Genuine enthusiasm for the challenges that come with working at a startup.
