Software Engineering Intern

About Base

Base is building the foundation of American power. The grid is the largest, most complex machine in the world. Yet it’s aging, struggling to keep up with today’s demand, and is unprepared for our electrified future.

Base is modernizing the grid as the first engineering-led, technology-driven power company. We’re deploying a nationwide network of distributed batteries that strengthens critical infrastructure and saves Americans money.

Our team of engineers, operators, creatives, technicians, and electricians design and deploy systems at speed. If you want to tackle the problem that will define this century and shape the future of American energy, now is the time. Join us.

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

: in homes, on the grid, and in how we grow.

- 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

- Fleet Software & Embedded Systems – 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.

We’re Building a Winning Culture And We’re Looking For People Who Are Up For The Challenge. Here’s What We Expect From Day One

- In-Person Only: We work full-time in the office. No hybrid. No remote.

- Challenge the Status Quo: Question assumptions. Fix broken systems. Principles > rules.

- Move Fast: Focus on what matters, act quickly, and learn by doing.

- Give & Get Feedback: Be direct, be humble. Challenge ideas–including your own.

- Own the Outcome: Take full responsibility. Deliver results. No excuses.

- Act Like an Owner: Be resourceful, mindful of impact, and committed to the business.

- Be Decisive: Drive clarity. Make bold calls with imperfect info.

- Bring the Intensity: This is not a 9-to-5. We're building something hard which requires real commitment.
