About TerraPower

TerraPower is a nuclear energy technology company based in beautiful Bellevue, Washington. We work to raise global living standards by creating new forms of energy. TerraPower aspires to develop scalable, sustainable, low-carbon and cost-competitive energy sources that will allow all nations to quicken their pace of economic development and reduce poverty. This mission-driven innovation distinguishes our efforts from other endeavors. Since 2008, TerraPower has been bringing together the strengths and experiences of the world’s public- and private nuclear energy sectors. With deep technical knowledge and commercial experience, our centerpiece technology is an advanced nuclear technology called the traveling wave reactor (TWR). TerraPower’s unique approach greatly simplifies the nuclear energy supply chain and significantly mitigates many shortcomings of today’s standard nuclear energy technologies. We’re a growing company and we continue to add talent from a variety of fields. TerraPower seeks to hire highly motivated and forward-thinking professionals interested in advanced nuclear energy research and development, and influencing change within the nuclear power landscape. We are an equal opportunity employer. However, TerraPower’s technology is controlled for export by various agencies of the U.S. Government. TerraPower must evaluate applicants who are foreign nationals (other than asylees, refugees, or lawful permanent residents) in accordance with U.S. Government export control requirements. To facilitate TerraPower’s export control reviews, you will be asked as part of the application process to identify whether you are a U.S. Citizen or national, asylee, refugee, or lawful permanent resident of the United States. Government export authorization approval times vary. Based on the business needs for a particular position, TerraPower may not consider a foreign national from a country if it is impracticable to obtain timely Government export approval.
