Senior Software Engineer, Backend

About Base

Base is America’s next-generation power company. We’re rebuilding the foundation of modern civilization–electricity–by deploying a vast network of distributed batteries that is transforming today’s fragile, centralized grid into a resilient and abundant system. We are engineers, operators, and creatives solving some of the most complex, interdisciplinary challenges of our time.

About the Role

We're building BaseOS — the operating system that runs the modern power company. It coordinates thousands of distributed batteries, powers our internal operations, and enables us to deliver reliable, low-cost electricity at scale.

As a senior, staff, or principal engineer on this team, you won't just build services — you'll define how the system works. You'll make architectural calls that other engineers build on top of, set the technical bar for the team, and take end-to-end ownership of the systems Base depends on every day. You'll be trusted to operate with minimal oversight on ambiguous, high-stakes problems — and to know which problems are worth solving in the first place. Your decisions will directly shape how power flows across the grid.
