About The Position

Astranis is seeking a Radiation Effects Test Engineer Intern for Winter 2027. This role involves supporting the modeling, analysis, and rigorous electrical testing of spacecraft hardware within the space radiation environment. The intern will have a direct impact on space vehicles by characterizing electrical component degradation and executing hardware testing at various laboratories across the U.S. Internships at Astranis typically last for twelve weeks and are hourly roles designed for students currently pursuing bachelor's degrees from four-year universities. The company prides itself on giving everyone a chance to do meaningful work on challenging projects, with past interns contributing to hardware/software for satellites and many becoming full-time employees.

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.

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.
