About

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. Job Description Tempo is seeking a highly motivated and skilled Engineering Technician with strong welding capabilities to produce engineered parts and assemble testing apparatus, instruments, sensors, prototypes, and power electronic components. The ideal candidate is a driven professional who has recently graduated from a strong technical program, has 2–4 years of hands-on experience, and is eager to bring their energy and foundational skills to a fast-paced startup environment. You will work both independently and collaboratively to bring our engineering designs to life. This role is integral to the development and refinement of high-temperature energy storage components, offering an incredible opportunity to work on complex R&D projects and grow your career at the cutting edge of thermochemical energy storage technology. Key Responsibilities • Interpret 3D CAD models, 2D drawings, and spec charts to plan and execute part manufacturing; measure, mark, and cut raw materials accordingly • Perform TIG/MIG welding on structural assemblies and operate machine shop equipment (mills, lathes, drill presses, band saws) to create or modify parts • Assist in assembling complex mechanical and electromechanical systems as required • Prepare finished components for dimensional accuracy, weld integrity, and defects for inspection • Modify and repair parts, prototypes, and test rigs to support agile R&D needs using welding, grinding, cutting, and machining techniques • Work with high-temperature and specialty materials (refractory metals, ceramics, alloys) to meet durability and performance requirements for thermochemical applications • Partner with engineers to interpret technical drawings, troubleshoot fabrication challenges, and recommend design improvements for manufacturability • Inspect fabricated and welded components for structural integrity, finish, and dimensional accuracy to ensure parts meet required tolerances • Maintain welding gear and machine tools in optimal working condition; follow all safety protocols when welding, handling high-temperature materials, and operating machinery • Record prototype builds, assembly procedures, fabrication parameters, and component modifications, providing real-time feedback to engineering and R&D teams Qualifications Required: • Associate degree in Mechanical Engineering Technology, formal welding certification, or completion of a technical/trade school program • 2–4 years of hands-on experience in mechanical fabrication, welding, and assembly; experience in an R&D or startup environment a plus • Proficiency in TIG and MIG welding on various metals • Exceptional safety acumen and commitment to safe work practices • Familiarity with manual mills, lathes, grinders, and general metalworking tools • Ability to read and interpret engineering drawings, blueprints, and technical specifications • Strong willingness to learn about high-temperature and specialty materials (ceramics, alloys, refractory metals) • Exceptional attention to detail with the ability to work to tight tolerances • Proactive learner with the ability to assist in troubleshooting basic fabrication challenges. …
