TITLE:Senior Radiochemist


TerraPower® is a nuclear energy technology company based in Bellevue, Washington. At our core, we are working to raise living standards globally. The essential factor? Energy. In 2006, the company 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. TerraPower’s mission is to be a world leader in new nuclear technologies, while developing innovators and future leaders in the nuclear field. TerraPower is committed to bringing sustainable, affordable and safe energy to address global issues. 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.

TerraPower 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.

Senior Radiochemist

TPI seeks to support revolutionary radiotherapies for treatments of cancers, such as prostate cancer, colorectal cancer, and non-Hodgkin’s lymphoma by supplying radioisotopes that currently cannot be accessed in amounts required to develop medical treatments. The Senior Radiochemist will support TPI’s efforts toward the long-term production of actinium 225, leveraging specific expertise and experience working with radionuclides at scales relevant to this goal.

This position interfaces with a dynamic interdisciplinary environment in which effective communication, team-work and collaboration is required, while maintaining composure to act safely, ensure quality of data, and enable timely decision-making. The position will require good judgement in ensuring regulatory compliance while delivering on commercial production and engineering design needs. The candidate must be capable of working closely with a focused and high achieving group, working with minimal day-to-day supervision, and relocating to the Everett, WA area.


The Senior Radiochemist’s primary responsibilities include:

  • Propose, develop, and conduct radiochemistry experiments and lead research campaigns focused on manufacture and purification of radioisotopes.
  • Assist in radiochemistry laboratory and system development, including leading design efforts for flexible experimental chemistry capabilities to support TerraPower R&D activities.
  • Provide radiochemistry support for the design, scale-up, start-up and ongoing production of radioisotopes and associated containment systems.
  • Assist in the development of novel projects related to TerraPower research emphasizing radioelements and nuclear technology.
  • Interface effectively with TerraPower quality assurance disciplines as needed to ensure quality of experiments, analytical methods, and designs are maintained and continuously improved.
  • Maintain laboratory procedures (e.g., calibration, analytical methods, notebook results preparation, usage documentation).
  • Perform all work in compliance with site safety and radiation protection guidelines, including effective teamwork and communication with health physicists, authorized users and RSO.
  • Emphasize safety in new and existing design and safe practices in all experimental activities

Key Qualifications and Skills

  • A doctoral level (PhD) degree with post-doctoral or relevant industrial experience in radiochemistry, chemistry, or equivalent with significant demonstrated hands-on laboratory experience and expertise in radiochemistry, radiochemical separations, and chemical synthesis. Alternatively, commensurate post-graduate industrial radiochemical research laboratory experience will be considered as a substitute for a doctorate for candidates with degrees at masters and bachelors level.
  • Extensive background in radiochemistry relevant to the purification and production of actinium-225.
  • Proficient in separation chemistry of lanthanide and actinide materials, and other radioisotopes with emphasis on column-based separations.
  • Proficient in activity, equilibrium, and kinetics calculations.
  • Demonstrated experience coordinating and delivering on complex technical tasks requiring input from multiple stakeholders.
  • Expertise in methods relevant to characterization of actinide compounds including alpha spectroscopy, gamma spectroscopy, ICP-OES, ICP-MS, spectroscopy (UV/Vis), chromatography (IC, HPLC, TLC), radiolabeling, and wet-chemistry techniques.
  • Demonstrated ability to structure and plan research projects involving radioactive material handling and radiochemical separations and reactions.
  • Experience leading the design of, and in executing complex experimental studies.
  • Experience working and communicating productively in a multidisciplinary team including R&D, production, quality assurance, and engineering design functions.
  • Experience working and handling a high level of radioactive materials within hot cells (preferable, but not essential), glove boxes (essential), fume hoods and on laboratory benchtops.
  • Ability to understand requirements (regulations, codes and standards, etc.), incorporate them into TerraPower documents, and provide associated guidance to TerraPower personnel.
  • Flexibility to work periodic off-hours in support of routine production.
  • Experience demonstrating the highest standards with respect to safety and radiation protection in all work activities and familiarity with radiation protection and NRC standards.
  • Strong organizational and communication skills including technical writing, presentation, and interpersonal skills.
  • The successful candidate will possess a high degree of trust and integrity, communicate openly and display respect and a desire to foster teamwork.
