We have an exciting opportunity for a Senior Systems Engineer to support one of our premier programs. In this role, you will provide technical leadership, systems modeling and analysis, design development support, and test expertise to Agile software development teams and engineering stakeholders. You will perform technical analyses and define system functionality by developing use cases, translating requirements into system capabilities, defining epics and features, and establishing system interfaces and acceptance criteria. You will support mission-level modeling and simulation of sensing and effects capabilities across the seabed-to-space domain, conduct multi-level operational analyses, develop integrated system-of-systems architectures, and apply operations research techniques to support complex mission solutions.

What You Will Do

• Develop innovative approaches and solutions to address some of our customers’ most complex technical challenges

• Collaborate with Agile development teams across diverse product areas, including sensors, effectors, command and control, and other mission-focused capabilities

• Develop, validate, and benchmark models (constructive, simulation, and systems-focused) to support integrated system-of-systems architecture solutions

• Lead the development of kill chain performance models, engagement models, military CONOPS visualizations, mission-level operations research, and multi-fidelity simulations

• Collaborate with multidisciplinary teams across Raytheon to integrate capabilities, technical expertise, and products across the organization
