This is a full-time, onsite role based at our headquarters in Denver, CO.

The successful candidate will be responsible for building the company’s technical capability in Flibe (Li₂BeF₄) and other molten salts, including chemistry control, materials compatibility, corrosion, thermophysical properties, tritium behavior, impurity control, salt processing, and measurements/instrumentation for advancing the technology development of our fusion plant power systems.

This individual will lead the design, commissioning, and management of the Molten Salt laboratory, establish experimental capabilities and procedures, and develop a research program that directly informs the design and operation of the company's fusion power plant. The role will work closely with other science departments and with engineering teams to translate experimental results into requirements and design solutions.

The ideal candidate will combine deep technical expertise in molten salts with hands-on laboratory experience and the ability to establish a new experimental capability from the ground up.
