About the role#
As a Process and Thermal Performance Intern, you will join the Core Technology team to support the analysis and development of thermal and fluid systems for high-temperature heat battery technology. You will perform engineering calculations that shape the design, optimization, and deployment of these systems.
What you'll do#
- Support thermal and fluid performance analyses using 1D simulation tools and first-principles hand calculations.
- Assist in sizing and performance evaluation of fluid system components, including pumps, blowers, fans, heat exchangers, valves, and dampers.
- Develop and validate steady-state and transient thermal models for energy storage and heat transfer systems.
- Perform pressure drop, flow distribution, and energy balance calculations for ducting networks, piping systems, and process loops.
- Apply thermodynamic and fluid mechanics principles to evaluate system efficiency and identify performance improvements.
- Assist in developing and maintaining engineering calculation packages, spreadsheets, and simulation scripts.
- Support test planning, process raw test data, and produce performance plots.
- Contribute to equipment specification and vendor data review.
- Participate in design reviews and prepare technical memos.
What you'll need#
- Currently pursuing a Bachelor’s or Master’s degree in Mechanical Engineering, Chemical Engineering, or a related discipline.
- Foundational understanding of energy systems, including thermal cycles, heat exchangers, pumps, blowers, fans, and air-handling equipment.
- Familiarity with 1D thermal-fluid analysis, including energy and mass balances, Bernoulli and Darcy-Weisbach principles, and pump/fan curves.
- Exposure to simulation or calculation tools such as AFT, Ebsilon, MATLAB, or Aspen Plus/HYSYS.
- Comfort working with engineering equations and unit conversions across SI and imperial systems.
- Strong academic record with a genuine interest in clean energy and climate technology.
- Excellent time management, communication, and technical writing skills.
Location & details#
- Locations: Alameda, California (Hybrid) or Orlando, Florida.
- Employment Type: Full-time.
- Compensation: $35 to $45 per hour.
- Status: Paid internship.
