Staff Data Engineer

Staff Data EngineerAt Copper, we're reinventing home appliances for an electrified future. Our flagship Charlie range pairs high-performance induction with integrated battery 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 our fleet grows, we're hiring a builder to own how data flows through the company — from the range in a customer's kitchen to the dashboards driving business decisions. You'll architect our fleet telemetry and time-series infrastructure, define and implement strategy for our business and CRM data, and build the pipelines and tools that turn product telemetry into actionable data. These systems underpin the diagnostic tools our customer team relies on for surfacing product performance data and demand-side grid support programs.This is a full-time position expected to be in-office 4 days per week. Our office is located in Berkeley, CA.We value a diverse workplace, and are assembling our team to match these values at this early stage.
