Reliability Engineer Photovoltaics

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 todays solar technology is good its not good enough.

Swift Solars 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 2026 we acquired Meyer Burgers HJT intellectual property and manufacturing assets giving us the worlds 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 Statesfrom 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. Were 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.

As a Reliability Engineer at Swift youll 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 modulesspanning environmental thermomechanical and accelerated life tests such as damp heat thermal cycling UV and outdoor exposurethen 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.

Youll 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 youll 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 35 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.

• 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.
