Antares Tech Stack

Compact nuclear microreactors for remote military and industrial sites

Defense and Space Manufacturing Los Angeles, CA 51–200 employees Founded 2023 Privately Held

Antares designs and manufactures compact nuclear microreactors for power-constrained environments—remote military bases, austere industrial sites, and eventual deep-space missions. The stack (Python, C/C++, COMSOL, ANSYS, Siemens NX, MATLAB) reflects a hardware-engineering org running physics simulation and CAD in parallel with embedded systems work. Active hiring skews heavily toward senior engineers and mid-level specialists, with only 10 roles posted in the last month despite 30 open positions—suggesting a funnel limited by specialized talent availability rather than demand.

About Antares

Founded in 2023, Antares is a Los Angeles-based nuclear hardware company building microreactors optimized for mobility and reliability in locations where traditional power infrastructure is impractical. The company is structured around three near-term vectors: integration with power conversion systems (Brayton cycle), prototype testing and full-rate production qualification, and development of in-house R&D and manufacturing facilities. Current focus spans neutronics modeling, hardware-in-the-loop test stands, vendor selection for manufacturing, and regulatory pathway work for nuclear licensing. The team draws from SpaceX, Relativity Space, Ursa Major, MIT, and U.S. Air Force backgrounds, with operations extending into Peru alongside U.S.-based activity.
