Lead Systems Engineer - Space, Viasat Government

Viasat, Inc.•Remote (excluding ND, VT, or RI), UNAVAILABLE

About The Position

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. As a Senior Spacecraft Systems Engineer, you will serve as a technical leader responsible for developing, integrating, verifying, and operating complex spacecraft systems that deliver critical mission capabilities. You will lead and/or oversee spacecraft architecture development, payload-to-bus integration, requirements definition and allocation, interface management, and mission-level systems engineering activities across the full spacecraft lifecycle. You bring expertise in spacecraft design, mission operations, systems engineering, technical integration, and cross-functional leadership. You are comfortable defining system solutions in ambiguous environments, influencing technical direction across organizations, and translating business and mission objectives into executable engineering strategies. In this role, you will collaborate across spacecraft subsystems, payloads, flight software, mission operations, ground systems, suppliers, and customers to deliver resilient and high-performing space systems while helping shape the future technical direction of the program.
