Software Engineering Intern

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.

At Base, we're building America's next-generation power company. Our software runs the whole stack: the firmware on batteries in real homes, the algorithms that trade power into ERCOT, the internal tools that let us deploy and operate the fleet, 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 entire company: balancing electrons in milliseconds, scaling operations into new markets, and automating things that 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.

• →

• 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.

• Clear, concise communicator who thrives in fast-paced, collaborative environments.

• Builder's mindset. Curious, self-directed, and drawn to problems that actually matter.

Interns at Base work in the same codebases as full-time engineers. No toy projects. You'll learn from a team that's built and scaled complex systems across energy, aerospace, and hardware industries. Your code will go live, power real homes, help us enter new markets, and shape how the grid actually works.

This isn't a typical internship. It's a chance to help rebuild the most important system in America. Come build with us.

About the Team

America's power grid is failing. Electricity costs have risen even as generation gets cheaper, and blackouts are getting more common. We're building the software that fixes it. Our team owns the entire stack: firmware that controls batteries in thousands of homes, trading algorithms that buy and sell power in real-time markets, distributed commanding systems that orchestrate a growing fleet as a single grid asset, factory software for our Austin manufacturing line, and the product experience that makes it all invisible to homeowners. If you want to write code that physically moves electrons, ships hardware, and reshapes critical infrastructure, this is the job.

Please note: Base is a startup, which means priorities shift and evolve quickly. Your role may expand or change based on the needs of the business at any given time, so the responsibilities listed may not be exhaustive.

• First Principles Thinking: Question assumptions. Principles > rules.

• Operate at Base Pace: Focus on what matters, act quickly, and learn by doing.

• Give & Get Feedback: Be direct, be humble, and maintain a growth mindset.

• Everyone’s an Owner: Follow through on commitments and own results.

• Strong Opinions, Loosely Held: Drive clarity and make calls with imperfect information.

• Committed to the Mission: Rebuilding the grid is a big challenge. We work hard because we care deeply about the impact we’re creating. We work in-person. It’s not a 9-to-5. We are all-in.

• Fun & Optimism Coexist with Grit: Collaboration and celebration coincide with the intensity of building real things.
