Staff Software Engineer

Staff Software Engineer

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 with 1 day flexible for in-office or remote work. 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.
• Design, implement, test, and ship features and systems across the cloud, mobile app, and internal tools used by customers, installers, manufacturing, and operations teams.
• 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.

What You'll Bring

• 10+ years of professional software development experience, ideally including time at a small or growing startup.
• Proven ability to independently drive large, ambiguous technical problems from definition through execution.
• Strong experience designing and building cloud-based systems (AWS or similar), including distributed systems and data pipelines.
• Comfort working across a modern web and application stack, including:
• TypeScript and/or Python
• React-based frontends
• SQL and database-backed systems
• Experience building production-quality systems with an emphasis on reliability, automated testing, and long-term ownership.
• Ability to work across teams and disciplines, communicating clearly with engineers, operators, and non-technical stakeholders.
• Comfort operating in ambiguity, making pragmatic tradeoffs, and taking responsibility for outcomes rather than just individual tasks.

Bonus Experience

• React Native or mobile app development.
• Experience working in or alongside Agile/Scrum teams.
• Experience building IoT-connected systems or working with device data.
• Familiarity with embedded software concepts (C/C++) or hardware-adjacent systems.
• Experience with protobufs, RPC frameworks, or event-driven architectures.
• Prior experience working at a hardware company.

Compensation & Benefits

The salary range for this role is $190,000 - $228,000. We are committed to equitable compensation, and we offer a generous benefits package to make sure you have the support you need.

Equal Employment Opportunity

We are committed to creating an equitable and inclusive environment for all our employees and are seeking to build a team that reflects the diversity of the people we hope to serve with our products. We are proud to be an equal opportunity employer.

About Us

Copper's vision is a future where every home is electrified with abundant clean energy. Our mission is to make decarbonization accessible to everyone by selling electric home appliances that enrich their daily lives. We're reducing the cost of electrification by integrating batteries into household appliances, starting with the stove. Our work has been funded by the Department of Energy, in an effort to reduce reliance on fossil fuels and increase energy resilience with products that are high-performance, safe, intuitive, and robust. As we build our team and pursue our mission, we do it with a strong sense of our core values because it's not just what you do, it's how you do it. You'll see this in high-level decisions, how we run meetings, our day-to-day work, hiring, and our interactions with customers and the broader community. We intend to have a massive impact on our team, our neighborhood, and the world.
