Test Technician IV

Antares•Los Angeles, CA

3d•$49 - $60•Onsite

About The Position

As a Senior Test Technician on the Antares team, you will work directly alongside Test Engineers to build, operate, instrument, and maintain test infrastructure for the R1 reactor. You will assemble test stands, integrate sensors and data acquisition systems, wire and plumb test hardware, operate tests safely and accurately, and document results and issues. This is a hands-on role that turns engineering concepts into physical test rigs, operates them during development and qualification testing, and provides real-time observations to engineers to enable rapid iteration. The role is essential to data quality, test repeatability, and operational uptime. Antares is developing mass-producible, inherently safe, deployable microreactors for terrestrial, underwater, and space applications. The company is based in Torrance, California, in a 322,000-square-foot facility with spaces for collaboration, research and development, and production.
