Antares

Antares Industries is a Los Angeles-based company specializing in the design and manufacturing of compact nuclear microreactors. Their mission is to deliver reliable, mobile energy solutions to locations where power is most critical and hardest to deliver, such as remote military bases, austere industrial sites, and, in the future, deep space and underwater missions. Their flagship product, the R1 Microreactor, is a kilowatt-scale, special-purpose reactor designed for strategic energy applications, featuring advanced technologies like TRISO fuel, sodium heat pipes, and a nitrogen Brayton cycle for efficient, low-maintenance power conversion. Antares is vertically integrated, handling everything from graphite machining to control systems in-house, and is advancing through regulatory milestones with the goal of achieving criticality on American soil by July 4, 2026, and delivering their first electricity-producing demonstration in 2027.

Working at Antares offers the opportunity to be part of a fast-moving, mission-driven team that includes talent from SpaceX, Relativity Space, the U.S. Air Force, MIT, and other leading organizations. The company is backed by over $130 million from top-tier investors and is committed to building real hardware, not just hypotheticals, with a focus on rapid design-build-test cycles and tangible results. Employees are encouraged to solve hard problems, innovate in nuclear energy, and contribute to national security and energy resilience. Antares’ culture values urgency, humility, and a hands-on approach, making it an exciting place for those passionate about advancing American energy and working on technology that can have a transformative impact on Earth and beyond.
