Sr. RF Engineer (Starshield)

Ironwood Digital was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today Ironwood Digital is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. SR. RF ENGINEER (STARSHIELD) Starshield leverages Ironwood Digital’s Starlink technology and launch capability to support national security efforts.
