Sr. Wireless Systems Engineer

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 BLE 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 the Senior Wireless Systems Engineer, you will be responsible for developing and implementing advanced algorithms that enable seamless wireless connectivity between terrestrial Bluetooth devices and satellites. You will work on designing and optimizing the wireless communication protocols essential for maintaining reliable connections across varying conditions in space and on Earth. Your expertise will be crucial in creating robust wireless systems that form the foundation of our satellite network.

You will be involved in all aspects of wireless communication system design, including modeling, protocol design, performance analysis, and system implementation. This role also involves collaborating closely with a cross-functional team of hardware and software engineers to integrate wireless systems into Hubble’s satellite network.

This is an ON-SITE Full-Time Position.
