Software Engineering Intern

About the role

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

At Base, we're building BaseOS: the operating system that runs the modern power company. It's the firmware on batteries in more than 15,000 homes nationally, the algorithms that balance power in real-time energy markets, the internal tools that deploy and operate a fleet installing roughly 150 batteries a day, and the product members use to see and control their energy.

As a software engineering intern, you'll ship real code that runs in production on systems that keep power flowing to real homes. You'll work on problems that touch the whole company: balancing electrons in milliseconds, scaling operations into new markets, and automating things most utilities still do by hand.

This is one of the few places where every line of code has real consequences, in homes, on the grid, and in how Base grows.

WHAT YOU'LL DO

- Build production systems. Design, build, and deploy production-grade software across the stack, from embedded firmware to backend infrastructure to member-facing products.

- Ship under real constraints. Write code that runs under real-world conditions, where failures have physical consequences. Reliability isn't an afterthought, it's the job.

- Scale Base's operations. Contribute to the internal tools that let us expand into new markets, handle paperwork and deployment complexity, and orchestrate field operations at scale.

- Work across domains. Partner with hardware, deployment, and operations teams to solve problems that span software and the physical world.

WHAT YOU'LL BRING

- A strong foundation in software engineering fundamentals: data structures, algorithms, systems design.

- Demonstrated ability to build and ship working software, through side projects, coursework, or prior internships.

- A clear, concise communicator who works well in a fast-paced, collaborative environment.

- A builder's mindset: curious, self-directed, drawn to problems that actually matter.

AREAS YOU CAN WORK IN

(Please indicate your area(s) of interest when applying)

- Member software. Everything close to the member: top-of-funnel marketing and growth, onboarding, and the support members get once they've signed up for Base, including bill pay, live telemetry, grid status, and the systems that keep answering correctly through retries, outages, and partial failures.

- Factory software. The platform that tracks everything moving in and out of Base's factory: parts, vendors, procurement, receiving, and inventory, plus the tools that connect what happens on the floor to what shows up in our financial systems. A core part of the job is replacing spreadsheets and manual reconciliation with Base-owned systems of record.
