Astranis

Radiation Effects Engineer Intern (Fall 2026)

San FranciscointernAdded today

About this role

Support Astranis' satellite development by testing spacecraft hardware and electrical systems exposed to space radiation. This 12-week internship involves characterizing component degradation, executing rigorous electrical tests, and collaborating across teams to ensure fault-tolerant systems operate reliably in harsh orbital environments.

What you'll do

Conduct electrical testing of fault-tolerant systems in radiation environments and document results
Create test plans, develop fixtures, and diagnose issues with clear technical documentation
Support radiation testing campaigns for TID and SEE characterization before/during/after exposure
Breadboard circuits, verify automated test setups, and fabricate cable harnesses
Collaborate cross-functionally to inform team decisions on radiation effects considerations

What they're looking for

Electronics lab equipment operation (oscilloscopes, multimeters, power supplies, source meters)
PCB design software (Altium Designer or equivalent)
Hardware design and hands-on electrical testing/troubleshooting
SPICE-based circuit simulation (LTSpice, PSPICE, ADS)
Soldering and cable harness fabrication
Space radiation environment fundamentals
PCBA and semiconductor component knowledge

Benefits

$29.00 per hour
12-week internship duration
Hands-on work with actual spacecraft hardware
Cross-disciplinary collaboration with experienced teams
Northern California headquarters location

Likely interview questions

Describe a time you designed, built, and tested an electrical circuit from scratch—what was your process for troubleshooting when something didn't work?
How have you used oscilloscopes and multimeters to diagnose electrical faults in your projects?

What experience do you have with Altium Designer or other PCB design tools, and what was your most complex board layout?
Walk us through how you would approach creating a test plan and fixture for characterizing component behavior under stress.
Why are you interested in space radiation effects, and what do you understand about how radiation degrades semiconductor devices?
Tell us about a time you worked on a cross-functional team—how did you communicate technical findings to people outside your discipline?
Have you used SPICE simulators to model circuit behavior, and if so, what was the application?
