Senior Supply Quality Engineer

Lunar Energy is a home energy technology company that designs and sells integrated clean energy systems for residential customers. Its flagship product, the Lunar System, combines solar power generation, battery storage, and smart energy management into a compact, aesthetically designed unit that allows homeowners to produce, store, and use their own clean electricity. The company also offers the Lunar App and Lunar AI to help homeowners monitor and optimize their energy usage, as well as a Virtual Power Plant (VPP) program called Gridshare that enables customers to share stored energy with the broader grid. Lunar Energy's mission centers on making clean energy accessible, affordable, and simple for everyday homeowners, with the broader goal of accelerating the electrification of homes — including solar, EV charging, heating, and cooking. The company has partnered with Octopus Energy to offer innovative battery electricity plans, reflecting its commitment to rethinking how residential energy is produced and consumed. Lunar Energy has raised $232 million in financing to support its growth and expand its installer partner network across the United States. Founded by engineers with backgrounds at Tesla, Lunar Energy differentiates itself through a platform-first approach that goes beyond a standalone battery product, positioning its system as the foundation for whole-home electrification. The company serves both homeowners and a network of certified installer partners, and has received notable press coverage for its role in redefining home energy with smarter, cleaner power solutions.

Delivering on that promise depends on the quality of every part that goes into our products. As our Sr. Supplier Quality Engineer, you make sure the components our suppliers ship meet our standards before they ever reach the line, so every home we power gets a product that lasts. This is a hands-on role spanning the full product lifecycle, from qualifying and developing suppliers through new product introduction and into sustaining quality once parts reach mass production.

Lunar Energy was founded to transition homes to 100% clean energy—making our electricity greener, our air cleaner and our energy more safe, secure and reliable for all. We’re a fast-growing, global company building the world’s best clean energy products to electrify all homes and connect communities to form clean, resilient virtual power plants.
