Engineer Jobs in Corbin, KY (NOW HIRING)

We're making energy fair, clean, and simple for all using technology. Octopus Energy started with a bold idea: to build Britain’s first truly digital energy supplier. By combining world‑class tech with brilliant humans who care deeply about customers and driving the renewable energy transition, we made it happen and in 2025, we became Britain’s largest energy supplier. Octopus Energy Group is a global energy transition collective. 10 businesses working across 4 continents to tackle energy transformation at nearly every front. And we constantly push to make energy better. Tirelessly campaigning for fair protections for customers. And building innovative technologies that forge a path to a green energy system. We’re made up of 10,000+ authentic, committed people working around the world on stuff you'd never expect. We're united by a shared goal: to drive the global green energy revolution.
