Wireless Communication Systems Engineer

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

As part of a hardworking team of engineers and specialists, you will develop and analyze wireless communication system algorithms and architectures for the Tera Wave custom silicon platform. You will work across communication systems, modem PHY/MAC, digital signal processing, RF, ASIC, and software teams to develop algorithms and system models and support their implementation in custom silicon.

You will contribute to the development of high-performance, power-efficient communication solutions for advanced space-based wireless systems, from algorithm development and system simulation through pre-silicon verification and post-silicon validation.
