Radiation Effects Engineer Intern (Fall 2026)

About the role

Astranis builds advanced satellites for high orbits, expanding humanity’s reach into the solar system. The Radiation Effects Engineer Intern will evaluate and electrically test fault-tolerant electrical systems operating in a radiation environment, assist in creating electrical test plans, develop test fixtures, and document test activities and results. They will support radiation testing campaigns to up-screen components for TID and SEE, focusing on electrical parametric characterization before, during, and after exposure. The intern will work in a cross-discipline manner across teams to inform their decisions with regards to radiation considerations and support test development and early-stage activities.

Responsibilities

• Evaluate and electrically test fault-tolerant electrical systems operating in a radiation environment
• Assist in creating electrical test plans, developing test fixtures, and documenting test activities and results
• Practice efficient issue diagnosis and draft clear documentation for review by the team
• Support radiation testing campaigns to up-screen components for TID and SEE, focusing on electrical parametric characterization before, during, and after exposure
• Work in a cross-discipline manner across teams to inform their decisions with regards to radiation considerations
• Support test development and early-stage activities, which include breadboarding electrical circuits, automated test setup verification, and basic cable harness fabrication

Requirements

• Currently pursuing a B.S. in Electrical Engineering, Computer Engineering, or a related engineering field
• A passion for hardware development, including working in a fast-paced environment and hands-on electrical testing and troubleshooting
• Strong proficiency with essential electronics lab equipment, including the standard use of oscilloscopes, multimeters, power supplies, and source meter units
• Experience with Altium Designer (or other PCB design software) for schematic capture and board layout
• Demonstrated ability to personally design, build, and rigorously test electrical hardware from scratch
• US Citizenship or Green Card

Bonus

• Familiarity with the space radiation environment and effects on semiconductor devices
• Experience with SPICE-based simulators (LTSpice, PSPICE, ADS, etc.) to simulate circuit behavior and faults
• Comfortable with soldering, rework, and building specialized test harnesses
• Familiarity with fundamental electronics concepts and components (integrated circuits, PCBAs, sensors) and how to benchmark their performance
• Experience with radiation transport software (FastRAD, Novice, MCNPX, etc.)
