Profile match
CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.

We are looking to add a Senior Staff Assembly, Integration & Test (AIT) Engineer emphasizing in Electrical Ground Systems Test to our team, providing expertise and peer leadership, with daily work in the labs supporting AI&T operations. If you are excited about working in a dynamic environment and are passionate about developing critical test systems for leading-edge spacecraft and aerospace communication systems, we would like to hear from you. The satellite team is creating a new business pipeline consisting of committed internal investments as well as future business contracts. Become part of CesiumAstro’s growth, success, and future!
