Radiation Effects Associate Engineer (Fall 2026)

Associate Engineer positions typically last for twelve weeks, and are salaried roles designed for students who have already received a bachelor's degree (or who will have done so before working at Astranis). As our Radiation Effects Associate Engineer, 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 are still a college student, please apply to join us as an Intern.

Role

• 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

• Have a four‑year B.S degree in Electrical Engineering, Computer Engineering, or a related engineering field by the time of start date
• 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
• Don’t meet them all? Not a problem. Please apply even if you do not meet all these criteria

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.)

The base salary for this position is $1,925 per week.

U.S. Citizenship, Lawful Permanent Residency, or Refugee/Asylee Status Required

(To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States, or other protected individual as defined by 8 U.S.C. 1324b(a)(3))
