Kairos Power

We are an engineering company that designs, licenses, and demonstrates advanced reactor technology. Our goal is to provide clean, affordable, and safe energy.

We develop the fluoride salt-cooled high temperature reactor (KP-FHR). This advanced reactor technology aims to be cost-competitive with natural gas in the U.S. electricity market and offer long-term cost reductions. Founded in 2016, our work builds on research from U.S. universities and national laboratories, aiming to accelerate innovative nuclear technology.

We reduce technical risk through an iterative testing approach. Our goal is to demonstrate a U.S. plant before 2030 and then rapidly deploy the technology. Our specialties include engineering (nuclear and mechanical), reactor technology, clean energy, and new product development.

We use technologies like KP-SAM simulation code, Building Information Modeling (BIM) with Revit and Navisworks, Finite Element Analysis (FEA), and a Manufacturing Enterprise System (MES).

Our mission is to help the world transition to clean energy. We aim to improve people’s quality of life and protect the environment.

Our team includes diverse individuals who excel in their fields and are committed to the clean energy transition. We foster a collaborative, fast-paced culture that supports our people and mission.

We’ve been recognized as a Top Workplace and a Family Friendly Business. Forbes has also named us one of America’s Best Startup Employers for three consecutive years. We also nurture early career talent through internships, co-ops, and on-the-job training.

We offer competitive compensation packages. Our employee benefits include medical, dental, and vision coverage for employees and their dependents, paid vacation, and 401(k) retirement plans. We also provide pre-tax health insurance, dependent care, and commuter benefits (FSA).

We are a diversity-focused, equal opportunity employer and participate in E-Verify. Our primary work location is Alameda, CA (onsite), but some roles may offer remote work. Certain positions may also require up to 10% travel.
