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 the operating system for American power. Our software is the brain that connects batteries, homes, neighborhoods, and the grid — and it’s also the engine that runs Base itself.

As a Software Engineering Intern, you won’t just watch from the sidelines. You’ll ship real code that runs in production, on systems that keep power flowing to real homes. You’ll help us solve problems that touch the entire company: balancing electrons in milliseconds, scaling operations across new markets, and automating processes that utilities still handle by hand.

This is an opportunity to work on one of the few systems where every line of code has real-world impact: in homes, on the grid, and in how we grow.

What You'll Do:

• Build Production Systems: Design, build, and deploy production-grade software across our stack, from embedded software to backend infrastructure to user-facing products.

• Ship Under Constraints: Write code that runs under real-world conditions, with real physical consequences if it fails. Reliability isn’t an afterthought: it’s the mission.

• Scale Base’s Operations: Contribute to the internal tools that let us expand into new markets quickly, handle permitting and deployment complexity, and orchestrate field operations at scale.

• Work Across Domains: Collaborate with hardware, deployment, and operations teams to solve problems that span software and the physical world.

What We're Looking For:

• 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 collaborative, fast-paced environments.

• Builder’s mindset: curious, self-directed, and eager to work on problems that actually matter.

Areas You Can Work In
(Please indicate your area(s) of interest when applying)

• Fleet Software – Build the edge software that keeps our batteries reliable and connected.

• Internal Software – Write the automation, data pipelines, and APIs that run Base as a company.

• Market Infrastructure – Design backend systems that power real-time algorithms and control our distributed fleet.

• Product Engineering – Build intuitive mobile and web experiences that let people see and control their energy in ways utilities never could.

Why Base?

Interns at Base work on 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. You’ll see your work go live, powering homes, helping us enter new markets, and directly shaping the future of the grid.

This isn’t just another 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 becoming 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.
