Radio Frequency (RF) Test Engineer Verified today

Hubble Network is building a global Bluetooth network dedicated to machine-to-machine connectivity. Our direct-to-satellite network operates modem-less and gateway-less from off-the-shelf Bluetooth Low Energy chips, serving logistics, AgTech, and maritime applications.

The Role

As RF Test Engineer at Hubble, you will ensure the reliability, performance, and longevity of our satellite hardware. You'll develop and execute test, validation, and quality-assurance strategies that qualify our wireless payloads, uncover weaknesses, and prove our hardware can thrive in the harshest environments space has to offer, including radiation, thermal cycling, and mechanical stress.

Your work spans the full lifecycle from design validation through flight readiness and into volume production. You'll be central to scaling reliable, mission-ready hardware as we build out the Hubble satellite constellation.

You'll work closely with cross-functional hardware, software, and mechanical teams to ensure reliability from initial design through manufacturing and in-orbit operation.
