MBSE & Digital Threads Engineer at Booz Allen in El Segundo, CA

Job description

MBSE & Digital Threads Engineer The Opportunity: Our team supports missions ranging from the Moon to the navigation systems people rely on every day. We define and model the functional breakdown of next-generation space and ground systems that provide positioning, navigation, and timing to military and civil users. We capture the concept of operations of lunar missions. We develop and deliver AI applications, including multi-agent reinforcement learning, that bring precision and speed to our customers’ toughest missions. We are looking for a technically competent and intellectually curious teammate to build the digital models that carry a system from concept through the full lifecycle. You will create, connect, and apply interdisciplinary digital models so teams can answer hard engineering questions with evidence, not slides. The work sits at the intersection of systems engineering, architecture, and data including specifications, interfaces, milestone products, and the digital thread that keeps them consistent as the design evolves. Familiarity with AI and large language models is a real advantage as we change how systems engineering is done for our customers’ mission-critical systems. You will work with real autonomy, partner across disciplines, and own analysis and products. At the senior end of this role, you will shape the approach, lead work through milestone reviews, and mentor others. What You'll Work On: Develop and maintain system models, architectures, and related engineering products for government or other mission-critical systems. Apply Model-Based Systems Engineering (MBSE) to produce technical specifications, interface control documents, and architecture views that programs can use. Support program milestone reviews with clear analysis, consistent artifacts, and answers stakeholders can stand behind. Use script, code, or low/no-code automation to remove repetitive work and improve model quality. Contribute to the team’s generative AI capabilities for MBSE, connecting engineering models and products with inference workflows, human review, and quality checks. Work directly with government clients, teammate contractors, and internal partners so technical decisions stay aligned with program goals. You Have: Experience with systems engineering analysis and products on government or mission-critical systems Experience with MBSE with tools such as Cameo, MagicDraw, Sparx EA, DOORS, or IBM Rhapsody used to build specifications, interface definitions, and system architecture Experience supporting systems engineering or program-management function through milestone reviews Knowledge of automation with scripts, code, or low/no-code tools Ability to build working relationships with government clients and contractor teammates Secret clearance Bachelor’s degree in a STEM field Nice If You Have: Experience extending a digital thread across requirements, architecture, interfaces, design, and verification Experience with cloud platforms such as AWS, Microsoft Azure, or Google Cloud Knowledge of Agile methods and DevSecOps tools Knowledge of large language model inference engines or frameworks and how to apply them to MBSE Possession of strong problem-solving skills with an attention to detail Master's degree in a STEM field Industry Certification such as OCSMP, ASEP, GCP, Azure, AWS, or Security+ Certification Clearance: Applicants selected will be subject to a security investigation and may need to meet eligibility requirements for access to classified information; Secret clearance is required.
