Job description

At MITRE, your passion fuels work that impacts our nation and improves lives. This is where your skills strengthen national security, cybersecurity, health, transportation, and citizen services. We’re a nonprofit engineering, applied research, and advanced technology organization working in the public interest. With objectivity and integrity at our core, we lead federally funded research and development centers for U.S. government agencies – collaborating with industry and academia to deliver integrated, high-impact solutions that advance our nation’s health, security, and prosperity. Our people tackle the toughest technical challenges, supported by competitive benefits, meaningful career development, and a culture of innovation, collaboration, and technical excellence. Choose MITRE for a career with purpose — and help shape the future.

The Systems and Operations Department (L626) within MITRE’s Systems Engineering Division in the Center for Engineering and Analysis delivers innovative, mission-focused solutions using a multidisciplinary systems engineering approach to address sponsor challenges critical to national security missions. We advance engineering rigor, operational relevance, and mission effectiveness across complex systems and enterprises, with core focus areas in Domain Systems Engineering, Lifecycle Systems Engineering, and Acquisition Systems Engineering. Our teams develop, assess, and transition engineering solutions, provide strategic technical vision, and deliver data-informed recommendations that enable sponsor mission success from tactical through enterprise levels.

Roles & Responsibilities:

The Systems and Operations Department is seeking a Principal Systems Engineer to support government sponsor mission needs across complex and evolving national security environments. The selected candidate will help define, design, architect, integrate, and transition complex mission systems by applying both Traditional Systems Engineering (TSE) and Model-Based Systems Engineering (MBSE) methods. The role requires the ability to work across technical, operational, acquisition, and programmatic stakeholders to translate mission needs into executable system concepts, architectures, requirements, roadmaps, integration plans, acquisition artifacts, and engineering recommendations. The selected candidate will be expected to:

• Apply systems engineering principles across the system development lifecycle, including mission analysis, concept development, system design, architecture definition, requirements development, integration, verification, validation, deployment planning, and technical transition
• Lead or support system design and architecture activities by translating sponsor mission needs, operational constraints, and capability gaps into system concepts, functional designs, technical approaches, and implementation options
• Develop, assess, and refine system architectures for complex mission systems, including operational views, functional architectures, logical and physical architectures, interfaces, data flows, dependencies, and integration points
• Apply TSE and MBSE methods to capture system behavior, structure, requirements, interfaces, constraints, verification relationships, trade space, risks, and technical decisions
• Lead and facilitate stakeholder engagements, workshops, interviews, and technical working groups to elicit, analyze, document, and validate clear, testable, and traceable mission, system, product, interface, performance, security, and operational requirements
• Perform engineering studies, trade analyses, and gap assessments to evaluate current-state systems, operational processes, technology limitations, interoperability challenges, and opportunities to improve mission outcomes
• Steer integration, test, verification, validation, deployment planning, and technical transition activities for complex systems, including integration sequencing, test objectives, success criteria, interface dependencies, and deployment readiness considerations
• Perform alternative analysis for government sponsors and program managers on mission context, capability needs, technical priorities, system roadmaps, technology insertion opportunities, acquisition strategies, and engineering approaches that support program objectives
• Guide acquisition planning and execution by contributing to Statements of Work, Statements of Objectives, Performance Work Statements, market research, acquisition strategies, evaluation criteria, technical evaluation plans, source selection documentation, and vendor assessments
• Direct multidisciplinary teams to develop and present technical artifacts, architecture briefings, decision papers, trade study results, requirements packages, interface documentation, and engineering recommendations for sponsor and leadership review
• Serve as a mentor to junior staff by providing guidance, feedback, and knowledge-sharing to support their professional growth and strengthen team capabilities
• Support to Intelligence Community

Basic Qualifications:

• Minimum of 10 years of related experience with a Bachelor’s degree; or 8 years and a Master’s degree; or a PhD with 5 years’ experience; or equivalent combination of related education and work experience
• Experience applying systems engineering practices to complex technical, operational, or mission-focused systems
• Experience with system design, system architecture modeling, requirements development, interface analysis, integration planning, verification and validation, and technical documentation
• Experience with both MBSE and traditional systems engineering approaches, including requirements analysis, functional decomposition, interface control, trade studies, risk analysis, technical reviews, and engineering decision support
• Ability to develop or review architecture products, requirements specifications, trade studies, technical plans, acquisition artifacts, and engineering recommendations
• Experience leading technical tasks, facilitating stakeholder workshops, coordinating multidisciplinary engineering teams, or advising senior technical and program leadership
• Ability to directly collaborate with government sponsors, program managers, technical teams, acquisition stakeholders, and mission users
• Strong analytical, verbal, and written communication skills, including the ability to define ambiguous problems, structure technical options, and brief technical concepts to both technical and non-technical audiences
• Ability to work both collaboratively and independently in a dynamic sponsor environment
• Willingness to work at various sponsor locations in the Northern Virginia area as needed
• Must have an active Top Secret/SCI with Polygraph U.S Government issued Security Clearance. Per the U.S. Government’s eligibility requirements, you must be a U.S Citizen to be considered for a security clearance.
