Join Viasat's Government organization as a Senior Staff Systems Engineer supporting the development of advanced RF sensing, signal exploitation, communications, and mission systems. This role serves as a lead system architect responsible for transforming customer mission needs into innovative technical solutions and well-defined system requirements.

The successful candidate will work across hardware, software, embedded systems, networking, RF, and sensing disciplines to develop system architectures and technical roadmaps for complex defense and aerospace applications. This role requires both strategic vision and hands-on systems engineering leadership to guide programs from concept development through deployment.

You will be responsible for:
* Developing system architectures, technical strategies, and implementation roadmaps for advanced mission systems.
* Translating broad customer objectives into system concepts, requirements, and technical solutions.
* Leading requirements development, decomposition, allocation, and traceability across hardware, software, networking, and sensing subsystems.
* Performing system-level trade studies to evaluate architecture options, technical risks, and performance objectives.
* Defining and evaluating communications, RF sensing, signal exploitation, and distributed system architectures.
* Collaborating with software, hardware, FPGA, embedded systems, and integration teams to ensure successful implementation of system requirements.
* Supporting technical planning, solution development, customer engagements, and proposal activities.
* Conducting technical reviews and presenting system architectures, concepts of operations (CONOPS), and design approaches to internal leadership and government customers.
* Supporting integration, verification, validation, and operational demonstrations.

* Providing technical leadership across multidisciplinary engineering teams.

* Bachelor's degree in Electrical Engineering, Computer Engineering, Systems Engineering, Physics, Applied Mathematics, or a related technical discipline. Advanced degree preferred.
* 10+ years of experience developing and architecting complex defense, aerospace, communications, sensing, or mission systems.
* Demonstrated ability to develop system vision, architectures, and requirements from broad customer goals and mission objectives.
* Experience with RF sensing, signal exploitation, communications systems, or related mission applications.
* Strong understanding of networked and distributed system architectures.
* Experience leading requirements analysis, allocation, verification, and validation activities.
* Familiarity with embedded systems, software development, and hardware design processes.
* Working knowledge of systems engineering methodologies, requirements management, and technical baseline control.
* Experience conducting system trade studies and technical performance analyses.
* Strong written and verbal communication skills, including customer-facing technical presentations and briefings.
* Ability to work effectively across multidisciplinary engineering organizations.
* Active Secret clearance and ability to obtain and maintain a Top Secret clearance along with SAP approvals.
* Willingness to travel up to 25%.

* Experience with distributed RF systems and networked sensing architectures.
* Background in RF direction finding, geolocation, spectrum monitoring, signal classification, or signal exploitation.
* Familiarity with software-defined radios and modern communication systems.
* Experience with Model-Based Systems Engineering (MBSE) tools and practices.
* Experience with requirements management tools such as DOORS, Jama, or equivalent.
* Hands-on experience with embedded processing platforms, FPGA-based systems, digital hardware, and networking technologies.
* Experience supporting DoD programs through customer engagement, capture, proposal development, and technical leadership activities.
* Active Top Secret clearance; TS/SCI preferred.
