Senior Manager, Hydrogen Isotope Science

The Tritium Technology Division at SRNL seeks a Group Manager to lead its Hydrogen Isotope Science Group, a team of scientists, engineers and technicians working on hydrogen, deuterium and tritium. The selected candidate will set the group's technical direction, grow its research portfolio and keep its people and facilities safe and productive. This is a hands‑on leadership role for a recognized technical expert who wants to build a team as much as a research program. The position reports to the Tritium Technology Division Director, within the Weapons Technology Directorate. The selected candidate will partner closely with program, operations and facility leaders across the lab.

About the group

The Hydrogen Isotope Science Group delivers science and engineering that underpin national security, fusion energy and the tritium supply. The R&D team works across four core areas:

• Hydrogen isotope science: fundamental behavior of protium, deuterium and tritium in gases, metals, hydrides and other materials, including sorption, diffusion, permeation and trapping.
• Processing: tritium handling, storage, purification, recovery and accountability, from bench scale to process‑scale systems.
• Separations: isotope separation methods such as thermal cycling absorption, cryogenic distillation, gas chromatography, palladium‑membrane and emerging approaches.
• Tritium effects on materials: aging and radiolytic effects, helium‑3 generation and embrittlement, hydrogen‑induced cracking and the long‑term performance of metals, polymers and components.
• Hydrogen Storage: Characterization of hydrides upon prolonged exposure to tritium, testing and performance under relevant conditions.

The group operates specialized laboratories and tritium‑capable facilities, and supports sponsors including DOE/NNSA, Office of Science, fusion energy programs and industry partners.
