Chemical Vapor Deposition Engineer (TRISO)

Valar Atomics is a nuclear energy company focused on scaling high-temperature gas reactors (HTGRs) for grid-independent industrial applications. The company is developing what it calls gigasites, large-scale facilities housing hundreds of nuclear reactors intended to power heavy industry, data centers, hydrogen production, and clean hydrocarbon fuel synthesis. Their reactor design uses TRISO fuel, a graphite moderator, and helium coolant, a combination the company highlights for its strong safety profile and proliferation resistance. By operating outside the traditional electricity grid, Valar Atomics aims to unlock economies of scale that have historically eluded the nuclear industry. Valar Atomics' mission centers on making nuclear energy the cheapest and most reliable energy source in the world, with a particular emphasis on decarbonizing industrial processes and enabling clean fuel production. Their hydrogen output, generated via a sulfur-iodine thermochemical cycle, can be combined with captured CO2 to produce synthetic hydrocarbons through a modified Fischer-Tropsch process, offering a pathway to drop-in clean fuels. The company also targets the surging power demands of AI data centers, which are projected to require over 200 additional terawatt-hours of grid power by 2030. The company is currently advancing its Ward 250 project, a test reactor being developed in partnership with the U.S. Department of Energy, the San Rafael Energy Research Center, and the State of Utah, with a target go-live date of July 4, 2026, America's 250th birthday. The reactor has already been physically transported to Emery County, Utah, with logistical support from the U.S. military. Four executive orders issued under the Trump administration provided a mandate supporting the project's accelerated deployment timeline.
