About The Position

We are seeking a hands-on Engineering Technician to support the operation and scale-up of our isotope separation systems in both lab and pilot production environments. This role is critical to maintaining system uptime, enabling experimental campaigns, and advancing our production capabilities. You will work closely with engineers and scientists to troubleshoot complex hardware systems, build new equipment, and keep our lab running at a high level of execution. Hexium is an early-stage hardware company operating at the intersection of laser science, plasma physics, and atomic physics. We're developing advanced isotope separation systems rooted in AVLIS (Atomic Vapor Laser Isotope Separation) technology to address a critical bottleneck in the supply of isotopes used in clean energy, medical, and advanced industrial applications. Our platform integrates high-power lasers, vacuum systems, and precision instrumentation to enable scalable isotope production. This is a rare opportunity to work hands-on with complex physics hardware in a small, fast-moving team. We are based in Austin, TX and offer a competitive compensation package that includes medical and dental benefits, 401(k) matching, employee stock options, bonuses, and paid time off.
