Spring 2027 Mechanical Engineering & Materials Science Co-Op
About Fourth Power
Fourth Power is commercializing a breakthrough energy storage system that stores electricity as extreme heat in carbon blocks and converts it back to power in seconds using thermophotovoltaic cells. The result is clean, dispatchable capacity with lower lifetime costs than building a new fossil-fueled plant.
We’re backed by leading climate tech investors, including Breakthrough Energy Ventures and DCVC, and we operate first-of-a-kind demonstration systems in Bedford and Middleton, Massachusetts.
Our culture is built on teamwork, continuous innovation grounded in first principles, and relentlessness in tackling hard problems. We’re looking for skilled, motivated people who share our passion for reliable, affordable, clean energy.
About the Program
Our engineering intern and co-op program runs in three sessions each year. Each session, we hire up to three students to work alongside our engineers and technicians on hardware. Our co-ops / internship positions are full-time. This is a fixed-term program and does not include a commitment of full-time employment after the session ends. This application is for Spring 2027 Co-Ops (January - May/June).
