Fiber Laser Engineer

MissionAetherfluxs mission is to deliver energy to planet Earth. Our work will make energy more accessible, establish American energy independence, power underdeveloped and disaster-stricken areas, and protect American warfighters. BackgroundAetherflux is taking a new approach to an old idea called space solar power. Our constellation of satellites will collect sunlight in Low Earth Orbit, convert it to electricity, and transmit power through infrared lasers to ground stations, providing reliable energy access where traditional delivery is expensive, challenging, or dangerous. Current energy systems rely on complex logistics and outdated infrastructure, making them vulnerable to natural disasters, extreme weather, and physical and cyber attacks. Aetherflux overcomes these challenges by enabling direct, on-demand, secure, and scalable 24-hour energy distribution from space. This can revolutionize energy generation and delivery, and enable new capabilities as we deliver power to remote regions, military bases, bespoke operations, and unmanned autonomous systems. Baiju Bhatt, who also co-founded Robinhood, founded Aetherflux in 2024. Inspired by his father's career at NASA, Baiju earned his B.S. in Physics and M.S. in Mathematics at Stanford before starting Robinhood, now a public company that has helped over 20 million Americans access the financial system. Aetherflux is currently self-funded through a $10 million investment from Baiju.This is an ambitious mission that demands extraordinary talent. Aetherflux's team has worked at places like Robinhood, SpaceX, NASA, Anduril, JPL, and the U.S. Navy, and is based in San Carlos, CA. If youre ready to solve complex technical challenges and help build the most important energy company in the world, we want to hear from you.
