Thermal Engineering Intern (June - August)

Exowatt is a next generation renewable energy company offering commercial and industrial customers a modular full-stack energy solution that can provide dispatchable power and heat for up to 24 hours per day, specifically designed to meet the needs of energy-intensive applications such as data centers. Our mission is clear, to make sustainable renewable energy always available and almost free. Exowatt is based in Miami, Florida and backed by notable investors such as a16z, Atomic, and Sam Altman.

The Thermal Engineering Intern will assist in the design, analysis, testing, and optimization of high-temperature thermal storage and heat transfer components for Exowatt’s thermal energy storage systems.

• Support thermal modeling and simulations for heat exchangers and storage systems.
• Assist in testing and data collection on thermal performance.
• Evaluate and improve material selection for high-temperature applications.
• Work with engineers to develop scalable solutions for thermal energy storage.

• Pursuing a degree (BS, MS, or PhD) in Mechanical Engineering, Aerospace Engineering, or a related field.
• Knowledge of heat transfer, thermodynamics, and fluid mechanics.
• Experience with thermal simulation tools (e.g., ANSYS, COMSOL, or similar).
• Hands-on experience with thermal testing and data analysis is a plus.

At Exowatt, interns gain hands-on experience working with cutting-edge energy technologies while contributing to real-world projects. If you are passionate about innovation and sustainability, we encourage you to apply!
