Software Engineer, Systems Integration

ABOUT BASE 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. ABOUT THE ROLE The Systems Integration team at Base is responsible for ensuring our power systems, inverters, and batteries work together as one reliable product in the real world. As a Software Engineer on this team, you will establish and lead the software-driven integration function, building the tools, pipelines, and team that allow Base to bring hardware, firmware, and software together into trusted, high-quality products at scale. You will work closely with Electrical, Mechanical, and Firmware Engineering to define how our systems should integrate end-to-end, and then prove it through rigorous, software-driven test and integration frameworks. This is an opportunity to shape how systems integration is done at Base, from first principles to implementation. What You'll Do: - Develop new software tools in python, c/c++, and golang that accelerate feature development. - Define and build the integration test pipeline running HIL and full-system tests on self-hosted CI runners. - Lead the development of integration software connecting inverters, batteries, and power systems, including gRPC/HTTP APIs, CAN interfaces (including ISO-TP and UDS), as well as UART/SPI/I2C. - Architect and oversee the development of integration test automation software, CI/CD pipelines, and infrastructure that validate the system as a whole. - Collaborate cross-functionally with firmware, cloud, and hardware teams to resolve integration issues, influence design decisions, and improve product reliability. - Generate and communicate detailed integration and system-health reports to support compliance, certification, and executive decision-making. Required Skills / Qualifications: - 3-5 years of experience in Python, Golang, and/or bare-metal C and C++, with a focus on systems integration, distributed systems, or embedded/software interfaces for hardware products - A systems-level mindset and passion for integrating hardware, firmware, and software into reliable, resilient products. - Expertise building integration test automation, CI/CD pipelines, and tooling that validate multi-subsystem software and hardware interactions. - Excellent communication skills and the ability to influence technical decisions across disciplines. 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. OUR VALUES - 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. DO THE BEST WORK OF YOUR LIFE AT BASE.
