Radiation Effects Engineer Intern (Fall 2026)

Astranis•San Francisco, CA

16d•Onsite

About The Position

Internships at Astranis typically last for twelve weeks, and are hourly roles designed for students who are currently enrolled at a four-year university. As our Radiation Effects Intern, you will be supporting the modeling, analysis, and rigorous electrical testing of actual spacecraft hardware within the space radiation environment. You will have a direct impact on our space vehicles by characterizing electrical component degradation and executing hardware testing at various laboratories across the U.S. If you have already graduated from a four-year university, please apply to be an Associate Engineer.

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

Nice To Haves

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.)

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
