New Mechanical Design Engineer San Carlos, California, United States Apply About the company 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.
