Software Engineering Intern

About the Role 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. What You'll Do Build production systems. Design, build, and deploy production-grade software across the stack, from embedded software to backend infrastructure to user-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 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 You'll Bring 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. 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 mobile and web experiences that let members see and control their energy in ways utilities never could. #J-18808-Ljbffr
