Job Description

One team. Global challenges. Infinite opportunities. At Viasat, we’re on a mission to deliver connections with the capacity to change the world. For more than 35 years, Viasat has helped shape how consumers, businesses, governments and militaries around the globe communicate. We’re looking for people who think big, act fearlessly, and create an inclusive environment that drives positive impact to join our team.


Our team is developing the gateway signal processing software for Viasat's third-generation, global satellite internet network. “Viasat-3,” our revolutionary GEO satellite, is unprecedented both in its terabit per second capacity and its flexibility in directing that capacity where it is needed in real-time. Viasat-3 Flight 1 will cover the Americas upon its launch in 2022, and Flights 2 and 3 will subsequently cover the Europe/Middle East/Africa and Asia/Pacific regions. These spacecraft require an equally innovative gateway architecture, and we are developing an ultra-high throughput GPU-based modem to that end. Our team is responsible for its design, implementation, integration, and test. 

We’re looking for a Software Engineer with real-time experience and an interest in signal processing and the latest parallel computing architectures and algorithms. In this role, you will develop, optimize, and test software to perform signal processing, data/configuration management, and failover for our modems, while remaining a critical part of the launch of Viasat's broadband internet service globally.
