About The Position

We are seeking a Test Engineer to drive experimental characterization and automation of our isotope separation systems. The Test Engineer is heavily involved in the R&D process with test fixture design, instrument evaluation, and diagnostic development to validate our design principles. The role is critical to growing our technology from prototype to commercial success. About Hexium Hexium is an early-stage, science-backed industrial technology company building hardware at the cutting edge of laser science, plasma physics, and atomic physics. We are developing advanced isotope separation technology to support the clean energy industry, with a long-term path toward scaled, commercial systems. At our current stage, much of the engineering work is centered on experimental R&D and prototype development. Engineers work hands-on in the lab to design, instrument, and automate experimental hardware, run iterative tests on evolving systems, and translate real-world data into insights that guide the next phase of development. We are based in Austin, TX and offer a competitive compensation package that includes medical and dental benefits, 401(k) matching, employee stock options, performance bonuses, and paid time off.
