Project Leo is an initiative to launch a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband internet connectivity to un-served and under-served communities around the world. In this role, you will be bringing that vision to life by architecting; developing and testing the embedded security systems software that provides the secured communications between the satellites to customer-terminals and the ground-based internet gateways.

Export Control Requirement:
Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Key job responsibilities
Join our Leo MAC Software team to revolutionize global connectivity through satellite communications. As a key innovator, you'll develop mission-critical embedded firmware that powers our ground terminal networks and satellite systems, directly impacting millions of users worldwide.

We're looking for a talented software engineer to architect and optimize Media Access Control (MAC) layer solutions for our next-generation satellite communication platform. You'll work at the intersection of space technology and wireless communications, leveraging your expertise in:

Bare-metal embedded systems
Embedded Linux development
Modern systems programming (Rust/C)


This role offers a unique opportunity to shape the future of satellite communications while working with a diverse team of industry experts. Your code won't just run on Earth - it will operate in space, helping bridge the digital divide and connect the unconnected.

The Role

Design and implement MAC layer protocols for wireless communication systems
Develop efficient real-time software for resource-constrained embedded platforms
Optimize protocol performance for latency-sensitive applications
Interface with PHY layer implementations and higher network stack components
Collaborate with hardware teams for efficient hardware/software integration
Develop automated testing frameworks for protocol validation
