Software Engineer, Payments

About Base

Energy is the defining challenge of our generation. Electrical grids are the largest, most complex machines in the world, and have been underinvested in for decades. They’re fragile, outdated, and failing to keep up with the demands of a modern, electrified world.

Base is fixing that. We are the first engineering-led, technology-driven power company deploying a nationwide network of distributed batteries – the fastest, most cost-effective way to add storage to the grid today. Every battery we install strengthens the grid, protects critical infrastructure, lowers energy costs for Americans, and moves the country toward true energy abundance.

If you want to tackle the problem that will define this century and shape the future of American power, now is the time. Join us.
