Astranis is seeking a Senior Radiation Test Engineer to lead radiation characterization and testing efforts for advanced satellites operating in high-orbit environments. The role combines hands-on technical expertise with strategic system design, focusing on ensuring spacecraft reliability in harsh radiation environments.
Key responsibilities include designing fault-tolerant electrical systems for radiation-exposed spacecraft, simulating and modeling geostationary (GEO) and geosynchronous transfer orbit (GTO) radiation environments, and coordinating comprehensive radiation testing campaigns to validate and upscreen components. You will work cross-functionally with the structures team to determine optimal shielding strategies and integrate radiation-hardened systems into spacecraft designs. The position also involves supporting broader electrical design, bringup, and test activities, plus contributing to team growth through recruiting and hiring.
Required qualifications include a BS in nuclear engineering, electrical engineering, physics, or equivalent field, with demonstrated hands-on experience in radiation environment characterization and testing. You must have deep knowledge of geostationary radiation effects (TID, SEE, DDD), experience designing and testing for radiation effects, and proficiency testing analog and digital circuits in high-reliability systems. US citizenship or green card is required due to export control regulations governing space technology.
Bonus qualifications include electromechanical design experience, hands-on lab testing at radiation facilities, dosimeter circuit design, and CAD/MCAD proficiency (Altium, Solidworks). Astranis offers competitive base compensation, significant equity via stock options, comprehensive healthcare, 401(k) matching, flexible PTO, and on-site catered meals. The company operates from a 153,000 sq ft Northern California headquarters with 450+ engineers and has $1B+ in commercial contracts with five satellites on orbit.
