Electrical Engineer

About Tempo Based in San Diego, California, Tempo develops thermochemical energy storage (TCES) systems designed for energy-intensive industries. The platform enables industrial operators to shift energy use over time by sourcing power when it is most cost-effective and enables the electrification of high-temperature industrial heat at a cost advantage to using fossil fuels. By storing electricity thermochemically, the system delivers a continuous stream of combustion-free, high-temperature air at up to 1,200°C. Tempo is backed by leading climate and energy investors, including Breakthrough Energy Ventures, Khosla Ventures, and Prelude Ventures. For more information, visit www.tempoenergy.com . The Role Tempo is seeking a Power Electronics & Controls Engineer to take meaningful ownership of power conversion system development within our engineering team. In this role, you will drive hardware design, through bring-up and field integration, and control development work effectively across engineering disciplines with a high degree of independence, and serve as a dependable technical resource for the broader team. This position is well suited for an engineer with a demonstrated track record of delivering power electronics hardware and control systems, sound technical judgment, and the ability to lead project work without close direction in a fast-paced, early-stage company environment. What You'll Do Circuit & System Design Design and optimize power conversion circuits — including DC/DC, AC/DC, and DC/AC topologies — supporting the charging and control of Thermal Battery Modules within the TCES system. Evaluate design approaches for gate drivers, custom magnetics, and protection circuitry, and provide well-reasoned recommendations for high-voltage, high-temperature, and harsh-environment applications. Identify and advance cost reduction opportunities across the Power and Rectifier cabinets, collaborating with mechanical, thermal, and manufacturing teams to translate des
