Radio Frequency (RF) Test Engineer

Hubble Network  · Seattle, Washington  · Oct 6, 2026

Hubble Network was founded with the intention of delivering on the promise of what Internet-of-Things (IoT) was supposed to be. We're building a global Bluetooth® network dedicated to machine-to-machine connectivity. We differentiate ourselves as the first modem-less and gateway-less, direct-to-satellite network from off-the-shelf Bluetooth® Low Energy chips. Hubble is ideal for applications in logistics, AgTech, and maritime where economies of scale for volume consumer and enterprise asset tracking is a priority. Our goal is to be the first billion-endpoint-connected network in the world. Hubble is an early-stage, venture-backed startup supported by some of the best investors in the world. In their previous lives, the founding team has been successful in raising $100s of millions in venture funding, developing the Amazon Sidewalk network, launching billions of dollars of space assets, and leading their teams to successful exits, both through acquisition and IPO. We are now looking to bring on talented team members who are the best at what they do to help us make Hubble a reality for the world. As a Radio Frequency (RF) Test Engineer at Hubble, you'll help ensure the reliability, performance, and longevity of our satellite hardware. You'll develop and execute the test, validation, and quality-assurance strategies that qualify our wireless payloads, uncover weaknesses, and prove that our hardware can thrive in the harshest environments space has to offer — including radiation, thermal cycling, and mechanical stress. Your work will span the full lifecycle — from design validation through flight readiness and into volume production — and...
