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
