Software Engineering Intern

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.

• Deployments / fleet software. The last-mile engine that gets batteries from warehouse to home: evaluating install sites, automating paperwork and scheduling, and dispatching the right local crews. This team also builds the field-based tools installers and electricians use on-site, backed by a shared work-order and task-automation platform other product surfaces build on.

• Base Power Platform. The B2B team building the APIs and services utility partners use to see and control their own Base battery fleets: fleet state, dispatch, and scheduling data served through typed, multi-tenant APIs, with dispatch commands that can't be duplicated or lost.

• Distributed compute. Base's newest bet: turning the residential power network into a distributed compute fleet. This small founding team is running early pilots and building the control plane (node enrollment, sessions, routing) that will let thousands of homes serve compute workloads reliably.

• Product Engineering. Product-focused, full-stack engineering role. This role leans slightly heavier on front-end skillsets and React/Typescript development. Product Engineers are used across all of the teams listed above.

Why Base?

Interns at Base work in the same codebase 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. Your code will go live on batteries running in real homes today, help us take the model into new markets beyond Texas and Illinois, 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.

Our Values

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