At Maiven Energy, we're working on real-world problems at the intersection of responsible AI and residential energy. Our aim is to make energy upgrades smarter, faster, and more accessible, while helping reduce carbon emissions. We're a small, mission-driven team punching way above our weight: we have large utility customers, contracts in multiple states, and a growing pipeline of programs launching later this year. We're venture backed and moving fast. We're hiring for three positions (US only): - Full-Stack Engineer – NestJS, React, Tailwind, TypeScript, Node, Postgres, AWS, Lambdas. [1] - Energy Modeling Engineer – Python, pandas, AWS, modeling frameworks (ResStock, OpenStudio, etc.). Experience with energy programs or building science is a huge plus. [2] - UX/UI Designer [no link] Looking for builders who want real ownership, thrive in early-stage startups, and move with urgency and care.
