Overview At Copper, we’re reinventing home appliances for an electrified future. Our flagship Charlie stove pairs high-performance induction with integrated energy storage to make the switch from fossil fuels a no-brainer. We’re a small, fast, collaborative team that ships, learns, and iterates quickly. As a Software Engineer, you’ll help build and scale the software systems that connect our appliances, cloud infrastructure, and customer-facing applications. You’ll work across cloud services, data pipelines, mobile and web applications, and the interfaces that tie our software to real hardware in people’s homes. This is a high-impact, hands-on role with end-to-end ownership. You’ll partner closely with a small, cross-functional team, while shipping mission-critical features that support customers, manufacturing, operations, and Copper’s broader climate mission. We’re looking for someone who thrives in ambiguity, drives clarity across boundaries, and can scale both systems and engineering practices as the company grows. . We value diversity and are committed to building a team that reflects a wide range of backgrounds, experiences, abilities, and perspectives. We’re especially focused on fostering an inclusive workplace where everyone can contribute to our shared mission. This is a full-time position and it is expected to be in-office 4 days per week. Our office is located in Berkeley, CA. What you'll do Own the design, implementation, and evolution of critical software systems spanning cloud infrastructure, mobile applications, and internal tools.

Own and grow data pipelines and cloud systems that power fleet visibility, analytics, and participation in programs such as virtual power plants. Partner with hardware, firmware, manufacturing, and product teams to build software that integrates cleanly with real devices and real-world workflows. Refine feature requirements, balancing user needs, system complexity, reliability, and long-term maintainability. Partner with engineering leadership to shape technical direction and prioritize high-impact work. Support mobile releases and QA, with a bias toward automation and repeatable processes. Lead by example through high-quality code, thoughtful design, and strong engineering practices. Contribute to code reviews and mentor other engineers through hands-on collaboration As the system matures, help support operational needs, including occasional on-call incident response outside of normal business hours.
