PCB design software (Altium Designer or equivalent)
Hardware design, build, and testing from concept to completion
SPICE-based circuit simulation (LTSpice, PSPICE, ADS)
Soldering and rework techniques
Space radiation environment and semiconductor effects
Radiation transport software (FastRAD, Novice, MCNPX)
Technical documentation and communication

Benefits

Hands-on experience with actual spacecraft hardware and real-world satellite technology
Work on high-impact projects serving government and enterprise customers
Direct influence on space vehicle reliability and performance
Exposure to cutting-edge space radiation testing and characterization
$1,925 weekly base salary
12-week structured program with mentorship from experienced engineers
