STC is seeking a Model-Based Mission Engineering Subject Matter Expert to develop innovative, model-centric solutions for complex defense systems and mission environments. In this role, you will help transform legacy mission architecture information into dynamic digital models, enabling data-driven decision-making, rapid integration, secure interoperability, and mission-level analysis across operational domains.

If you are passionate about MBSE, digital engineering, mission-focused architectures, and working with cutting-edge technologies, this is an opportunity to make a meaningful impact.

Responsibilities

• Develop, analyze, and manage mission, operational, system, interface, and cybersecurity requirements throughout their lifecycle.
• Develop and maintain mission engineering architectures and model-based artifacts that connect operational scenarios, mission threads, systems, interfaces, simulations, and data sources.
• Use MBSE tools, SysML, and UAF to create and maintain behavioral, structural, parametric, requirements, and interface models supporting mission engineering analysis and decision-making.
• Support the transition from static, document-centric engineering artifacts to an integrated, model-centric digital engineering environment and authoritative source of truth.
• Model, assess, and support integration of mission systems, sensors, payloads, networks, hardware, software, and simulation environments across complex operational architectures.
• Collaborate with system, mission, cybersecurity, M&S, software, hardware, data, and operational subject-matter experts to define and validate mission engineering solutions.
• Support Live, Virtual, and Constructive (LVC) environments and automated M&S workflows that enable multi-domain mission engineering and joint-force coordination.
• Perform mission and system requirements verification, traceability, model validation, technical reviews, and compliance assessments in support of design reviews, prototype testing, and integration events.
• Identify technical risks, assess the mission impacts of design changes, track performance measures, and provide clear, model-based technical recommendations to program stakeholders.

Qualities of a Successful Candidate

• Self-starter who can work with minimal supervision and exercise sound judgment in defining technical objectives and approaches.
• Expert-level capability with system and enterprise modeling tools and experience developing behavioral, structural, parametric, requirements, and interface models.
• Strong understanding of mission engineering principles, operational analysis, systems-of-systems integration, and digital engineering practices.
• Proactive individual who can rapidly learn new technologies and collaborate effectively with domain SMEs, engineers, program managers, customers, and government stakeholders.
• Inquisitive, analytical, and motivated engineer with strong systems engineering and SysML and UAF modeling skills.
• Effective communicator who can translate complex technical, operational, and modeling concepts into clear products for technical and non-technical audiences.

Why Join Us?

• Join a team of world-class MBSE, mission engineering, digital engineering, and M&S professionals.
• Work on high-impact defense initiatives that advance data-driven acquisition, accelerate integration, and improve mission-level decision-making.
• Help solve challenging multi-domain integration problems involving operational scenarios, system interfaces, cybersecurity constraints, and LVC mission environments.
• Exercise considerable latitude in determining objectives and approaches to assignments, with the freedom to innovate and excel.

If you are a forward-thinking engineer with a passion for mission engineering, MBSE/DE, innovation, and technical excellence, apply now to become part of our team.

• Education/Experience:
• Bachelor’s degree with 10-12 years of relevant experience; or
• Master’s degree with 8-10 years of relevant experience; or
• PhD with 5-7 years of relevant experience.
• Demonstrated experience with:
• Dassault Systèmes Cameo Systems Modeler and/or Cameo Enterprise Architect
• SysML
• Unified Architecture Framework (UAF)
• Object-Oriented Systems Engineering Method (OOSEM)
• MBSE architecture development and requirements traceability
• Mission engineering, system-of-systems engineering, operational architecture development, or enterprise architecture
• Modeling and Simulation, preferably including LVC environments
• Experience supporting DoD, Navy, joint, or other defense mission environments is preferred.
• Must possess and maintain an active Secret security clearance.
