Radiation Effects - Team Lead

As a team, we’ve launched five satellites into orbit, signed ten commercial deals worth over $1 billion in revenue, raised over $750 million from top global investors, and recruited a team of over 400 world-class engineers. We all work out of our (legendary) San Francisco office, which was once used to build ships during the World Wars.

Our satellites, which operate from geostationary orbit (GEO), weigh only 400 kg and utilize a proprietary software-defined radio payload. Each satellite can connect over two million people, and we’re very excited for the impact we’ll soon have in the Philippines, Mexico, and more!

Backed by substantial funding and a passionate, collaborative team, we offer a rewarding work environment where you'll learn and make a significant impact, no matter where you are in your career.

Radiation Effects Team Lead

As a Radiation Effects – Team Lead, you will play a critical role in ensuring the reliability and resilience of our satellites in space, while leading and growing a high-performing team.

Role:

• Lead and mentor a team of Radiation Effects Engineers, setting technical direction and guiding execution.
• Develop and own Astranis’s long-term strategy for radiation effects analysis, testing, and mitigation.
• Oversee simulation and modeling of space radiation environments in GTO, GEO, and other higher orbits.
• Direct radiation testing campaigns, including component up-screening, characterization, and failure analysis.
• Partner with Electrical, Mechanical, Systems, and Reliability teams to ensure spacecraft-level resilience.
• Establish and improve processes for radiation analysis, documentation, and test execution.
• Stay hands-on with technical work—supporting analysis, running test campaigns, and reviewing designs.
• Represent the team in cross-functional reviews and communicate results, risks, and recommendations to leadership.
• Recruit, onboard, and develop new team members to scale Astranis’s radiation engineering capability.

Requirements:

• Bachelor’s degree in nuclear engineering, electrical engineering, physics, or a related field.
• Proven industry experience in radiation effects on electronics, including TID, SEE, and charging.
