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.\nTempo is backed by leading climate and energy investors, including Breakthrough Energy Ventures, Khosla Ventures, and Prelude Ventures.\nFor more information, visit www.tempoenergy.com.\nTempo is seeking a motivated, hands-on Engineering Intern to support the development and experimental validation of its high-temperature thermal energy storage technology.\nThe intern will work primarily on the SoFuel test stand, an experimental system designed to investigate high-temperature solid pellet storage, gas-solid heat transfer, granular material flow, and thermal system performance. This position offers an opportunity to work directly with experimental hardware, operate and improve a research-scale test system, analyze test data, and contribute to the development of next-generation energy storage technology.\nWe are looking for someone who enjoys building, testing, troubleshooting, and solving practical engineering problems in a laboratory environment.\nKey Responsibilities\n1. Experimental Testing and Test Stand Operation\nAssist in preparing, setting up, and operating the SoFuel experimental test stand under the supervision of experienced engineers.\nExecute experimental test plans to evaluate gas-solid heat transfer, particle flow behavior, and system performance.\nMonitor operating parameters, including temperature, gas flow rate, pressure, and particle movement.\nConduct repeatability tests and evaluate the effects of changing operating conditions.\nFollow established operating procedures and safety protocols during testing.\n2. Instrumentation and Data Acquisition\nSet up, calibrate, and troubleshoot sensors and measurement equipment, including thermocouples, flow meters, pressure transducers, and distance sensors.\nMonitor and record experimental data using the test stand's data acquisition and control systems.\nVerify data quality, identify measurement anomalies, and maintain organized experimental records.\nSupport improvements to instrumentation and data collection procedures.\n3. Troubleshooting and Test Stand Improvements\nAssist in identifying and resolving operational issues such as particle clogging, inconsistent flow, temperature fluctuations, and sensor malfunctions.\nSupport mechanical modifications, component replacement, and routine maintenance of the test stand.\nWork with engineers to evaluate improvements to gas flow control, particle discharge mechanisms, and test stand reliability.\nHelp implement and validate improvements to operating procedures and control sequences.\n4. Data Analysis and Reporting\nProcess and analyze experimental data using Excel, Python, MATLAB, or similar tools.\nGenerate plots showing temperature profiles, flow behavior, pressure changes, and system performance.\nCompare experimental results across different operating conditions.\nPrepare concise technical summaries, test reports, and presentations documenting results and observations.\nMaintain accurate test logs and document experimental findings and recommended improvements.\nRequired Qualifications\nCurrently pursuing a BS or MS degree in Mechanical Engineering, Chemical Engineering, Aerospace Engineering, Materials Science, or a related engineering discipline.\nStrong interest in hands-on experimental engineering and laboratory testing.\nBasic understanding of thermodynamics, heat transfer, and fluid mechanics.\nFamiliarity with laboratory instrumentation and data acquisition.\nProficiency in Microsoft Excel and basic engineering data analysis.\nAbility to work independently on assigned tasks while collaborating with a multidisciplinary engineering team.\nGood problem-solving, troubleshooting, communication, and documentation skills.\nWillingness to work with experimental hardware in a laboratory environment and follow strict safety procedures.\nPreferred Qualifications\nPrevious experience with experimental test stands, laboratory equipment, or engineering research projects.\nExperience with thermocouples, pressure sensors, flow meters, valves, or data acquisition systems.\nFamiliarity with Python, Arduino C#, LabVIEW, or similar software for data processing and automation.\nExperience with mechanical assembly, fabrication, or troubleshooting.\nBasic understanding of control systems, programmable controllers, or automated test equipment.\nExperience with high-temperature equipment, furnaces, granular materials, or gas-solid flow systems.\nFamiliarity with CAD software such as SolidWorks is a plus.\nWhat You Will Gain\nHands-on experience operating and troubleshooting a high-temperature experimental system.\nPractical exposure to thermal engineering, fluid mechanics, instrumentation, and control systems.\nExperience designing and executing experiments and interpreting real-world engineering data.\nOpportunities to work directly with experienced engineers and researchers developing advanced energy storage technology.\nExperience contributing to an active R&D program, from experimental testing through analysis and technical reporting.\nCompensation\nThe pay rate for this internship is $30 per hour. Our pay rates are determined by role, level, and location. Within a range, individual pay may vary based on factors including academic level, relevant skills, and experience.\nWorking at Tempo\nTempo is a lean organization working on exciting challenges, and the people who thrive here share a few things in common beyond their technical skills.\nClear, direct communication: You professionally say what you mean, lead with empathy, use tact, ask when you're unsure, and keep the people around you informed without being asked. At a company our size, communication gaps are expensive, and good communicators add to success and efficiency!\nLow-ego helpfulness: You're willing to jump in on work that isn't strictly yours, whether that's helping a teammate debug something, lending a hand in the shop, or flagging an issue you noticed outside your lane. No one here succeeds in a silo.\nIntellectual curiosity: You're genuinely interested in how things work, not just your piece of it, but the broader system. Tempo sits at the intersection of chemistry, mechanical engineering, power electronics, and software; the more you understand about the whole, the more valuable you become.\nBusiness awareness: You understand that your work exists in a business context. You think about cost, timeline, and tradeoffs-not just technical elegance-and you make decisions accordingly.\nComfort with ambiguity: Processes here are still being built. You can make progress without a perfect playbook, and you know when to ask for direction versus when to use your judgment and move forward.\n Accountability: You own your outcomes, including the misses. When something goes sideways, the instinct here is to fix it and learn from it, not to explain why it wasn't your fault. \n\nThis job description is intended to provide a general overview of the position and is not an exhaustive list of duties, responsibilities, or qualifications. Tempo reserves the right to modify, add, or remove responsibilities as business needs evolve. Employees may be asked to perform duties outside of those listed above from time to time.\nTempo is an equal opportunity employer.
