Senior Analytical Chemist

Terra Power is a nuclear technology company based in Bellevue, Washington. At its core, the company is working to raise living standards globally through a more affordable, secure, and environmentally friendly form of nuclear energy along with innovations in medical isotopes to improve human health. In 2006, Terra Power originated with Bill Gates and a group of like-minded visionaries who evaluated the fundamental challenges to raising living standards around the world.

They recognized energy access was crucial to the health and economic well-being of communities and decided that the private sector needed to take action and create energy sources that would advance global energy deployment. Terra Power's mission is to be a world leader in new nuclear technologies, while developing innovators and future leaders in the nuclear field. As a result, the company's activities in the fields of nuclear energy and related sciences are yielding significant innovations in the safety and economics of nuclear power, hybrid energy and medical applications – all for significant human health benefits.

Terra Power is seeking to hire highly motivated and forward-thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes. Terra Power is an Equal Opportunity Employer. We do not discriminate in hiring on the basis of sex, gender identity, sexual orientation, race, color, religious creed, national origin, physical or mental disability, protected Veteran status, or any other characteristic protected by federal, state, or local law.

Terra Power, LLC is committed to delivering transformative nuclear technologies that provide safe, cost-effective, and carbon-free energy solutions, supporting global decarbonization goals. The Natrium program is a cornerstone of this effort, and we are seeking a highly skilled and motivated Senior Analytical Chemist to join our team.

This role offers a unique opportunity to shape the analytical foundation of the Natrium advanced reactor program. As a member of the Natrium Central Chemistry team, you will be directly responsible for advancing the chemical understanding of Natrium systems and processes and for developing robust analytical and experimental capabilities that support the characterization and chemistry control of sodium, solar salt, fuel/material-related samples, cover gas, and other Natrium process streams.

Reporting to the Natrium Central Chemistry Discipline Senior Manager, you will serve as both a technical leader and hands-on contributor, designing experiments, developing robust analytical methodologies, setting up and operating laboratory equipment, analyzing and interpreting experimental data, and providing critical data that underpins reactor safety, materials performance, chemistry control, and operational readiness. The position requires deep technical expertise, strong experimental judgment, and a strong collaborative spirit to interface effectively with colleagues across design, operations, materials, fuel, safety, testing, and safeguards teams.

• Lead development and implementation of robust analytical methods and procedures for Natrium sample characterization, including ICP-MS, ICP-OES, gamma spectroscopy where applicable, and other relevant techniques
• Lead and perform thermophysical and thermal characterization activities using techniques such as DSC and TGA, including experimental planning, data collection, analysis, and interpretation
• Perform and interpret thermodynamic calculations using Fact Sage, Thermochimica, or similar tools to support sodium, solar salt, cover gas, fuel/material, and impurity chemistry evaluations
• Design, set up, execute, and document laboratory experiments supporting Natrium chemistry, materials, and process-development needs
• Develop experimental approaches to address technical questions involving sodium, salts, cover gas, corrosion products, impurities, materials, and other Natrium-relevant systems
• Develop, generate, and review the generation and review of technical work products such as certificates of analysis/conformance, research reports, procedures, and publications
• Manage analytical scope related to measuring purity, and performing mass balance evaluations of Natrium-relevant materials and analysis of in-process samples for quality control
• Lead the…
