R&D Test Engineering Intern (SoFuel)

About the Role

Tempo is seeking a motivated, hands-on Engineering Intern to support the development and experimental validation of its high-temperature thermal energy storage technology. The 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. We are looking for someone who enjoys building, testing, troubleshooting, and solving practical engineering problems in a laboratory environment.

Key Responsibilities

• Experimental Testing and Test Stand Operation
• Assist in preparing, setting up, and operating the SoFuel experimental test stand under the supervision of experienced engineers.
• Execute experimental test plans to evaluate gas–solid heat transfer, particle flow behavior, and system performance.
• Monitor operating parameters, including temperature, gas flow rate, pressure, and particle movement.
• Conduct repeatability tests and evaluate the effects of changing operating conditions.
• Follow established operating procedures and safety protocols during testing.
• Instrumentation and Data Acquisition
• Set up, calibrate, and troubleshoot sensors and measurement equipment, including thermocouples, flow meters, pressure transducers, and distance sensors.
• Monitor and record experimental data using the test stand's data acquisition and control systems.
• Verify data quality, identify measurement anomalies, and maintain organized experimental records.
• Support improvements to instrumentation and data collection procedures.
• Troubleshooting and Test Stand Improvements
• Assist in identifying and resolving operational issues such as particle clogging, inconsistent flow, temperature fluctuations, and sensor malfunctions.
• Support mechanical modifications, component replacement, and routine maintenance of the test stand.
• Work with engineers to evaluate improvements to gas flow control, particle discharge mechanisms, and test stand reliability.
• Help implement and validate improvements to operating procedures and control sequences.
• Data Analysis and Reporting
• Process and analyze experimental data using Excel, Python, MATLAB, or similar tools.
• Generate plots showing temperature profiles, flow behavior, pressure changes, and system performance.
• Compare experimental results across different operating conditions.
• Prepare concise technical summaries, test reports, and presentations documenting results and observations.
• Maintain accurate test logs and document experimental findings and recommended improvements.

Requirements & Tech Stack

• Currently pursuing a BS or MS degree in Mechanical Engineering, Chemical Engineering, Aerospace Engineering, Materials Science, or a related engineering discipline.
• Strong interest in hands-on experimental engineering and laboratory testing.
• Basic understanding of thermodynamics, heat transfer, and fluid mechanics.
• Familiarity with laboratory instrumentation and data acquisition.
• Proficiency in Microsoft Excel and basic engineering data analysis.
• Ability to work independently on assigned tasks while collaborating with a multidisciplinary engineering team.
• Good problem-solving, troubleshooting, communication, and documentation skills.
• Willingness to work with experimental hardware in a laboratory environment and follow strict safety procedures.

Qualifications

• Previous experience with experimental test stands, laboratory equipment, or engineering research projects is preferred.
• Experience with thermocouples, pressure sensors, flow meters, valves, or data acquisition systems is preferred.
• Familiarity with Python, Arduino C#, LabVIEW, or similar software for data processing and automation is preferred.
• Experience with mechanical assembly, fabrication, or troubleshooting is preferred.
• Basic understanding of control systems, programmable controllers, or automated test equipment is preferred.
• Experience with high-temperature equipment, furnaces, granular materials, or gas–solid flow systems is preferred.
• Familiarity with CAD software such as SolidWorks is a plus.

Compensation

• The pay rate for this internship is $30 per hour.
