As an integral member of a Hypersonic platform development team, the successful candidate will assist in standardizing digital engineering and systems engineering practices and tools, including Cameo, to identify challenges and formulate candidate solutions within complex, highly interdependent systems and programs. A strong Digital Engineering background, coupled with traditional systems engineering experience is what is required for this position.

The Systems Engineer will utilize MBSE tools to develop system models and simulations for analysis and validation, work closely with stakeholders to define system requirements and constraints, and conduct trade-off analyses to optimize system characteristics. The selected candidate will develop and maintain system architectures and interfaces, collaborate with hardware and software engineers to integrate system components, and support the verification and validation of systems using models. Additionally, the candidate will provide technical expertise and guidance on MBSE practices, ensuring effective collaboration and successful project outcomes.
