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.MITRE Technology and Engineering (MTE) System Engineering Technical Division is seeking a Senior Mission Engineerto support defense mission engineering, system of systems analysis, experimentation, and decision-support activities for complex operational missions. The candidate will help decompose missions into mission elements, characterize operational scenarios and vignettes, develop mission threads, define mission measures and metrics, analyze baseline and alternative mission approaches, and translate analytic findings into actionable recommendations for government and program stakeholders.\nRoles and Responsibilities:\nFrame mission engineering problems and investigative questions: Define the mission problem, analysis purpose, decision context, assumptions, constraints, and investigative questions that guide the mission engineering effort.\nEngage stakeholders and subject matter experts: Coordinate with operators, government customers, engineers, modelers, intelligence analysts, test teams, and program leadership to validate mission context, assumptions, data sources, and analytic findings.\nCharacterize missions, scenarios, and operational environments: Develop mission context descriptions, CONOPS, scenarios, vignettes, threat representations, environmental conditions, operational timelines, and relevant mission constraints.\nDevelop mission measures and analytic metrics: Define and apply Measures of Success, Measures of Effectiveness, Measures of Performance, key mission indicators, and supporting metrics to evaluate mission outcomes and system contributions.\nCreate and assess mission architectures: Develop operational, functional, logical, and system of systems architecture products that capture mission activities, actors, systems, interfaces, dependencies, information flows, and operational relationships.\nAnalyze baseline and alternative mission approaches: Compare current-state mission execution against alternative architectures, concepts, capabilities, technologies, or operational approaches to identify gaps, risks, dependencies, and improvement opportunities.\nConduct mission analysis using modeling and simulation capabilities: Develop run matrices, excursions, sensitivity cases, experiment objectives, data collection plans, and analysis methods to evaluate system of systems performance in mission context.\nEvaluate results and assess mission impacts: Analyze quantitative and qualitative results, validate findings with stakeholders and SMEs, assess uncertainty and confidence, and determine how systems, capabilities, or changes affect mission success.\nDeliver decision-ready recommendations and reusable mission engineering artifacts: Produce briefings, reports, visualizations, models, datasets, assumptions, findings, recommended mission architectures, and curated digital artifacts that support acquisition, prototyping, experimentation, and capability decisions.\nMinimum Qualifications:\nBachelor’s degree and 5 years of experience in systems engineering, modeling and simulation, software engineering, computer science, or related disciplines.\nExperience supporting defense, aerospace, intelligence, national security, or other mission-critical technical programs.\nExperience with analysis and data tools such as but not limited to Python, MATLAB, R, SQL\nExposure to architecture/modeling tools: iGrafx, CAMEO, Rhapsody, or equivalent\nExposure to modeling languages and frameworks: SysML, BPMN, UAF/UAFML, or related methods\nExposure to simulation and mission analysis tools: Simulink, AFSIM, ITASE, NGTS, STL/Systems Tool Kit, OneSAF, or similar tools\nDemonstrated ability to analyze complex missions, operational scenarios, system dependencies, system of systems interactions, or capability gaps.\nExperience developing or supporting at least several of the following: mission threads, operational scenarios, vignettes, CONOPS, use cases, functional flows, system architectures, interface concepts, requirements, measures and metrics, run matrices, trade studies, or analysis reports.\nAbility to communicate complex technical and operational findings clearly through briefings, white papers, visualizations, technical reports, and stakeholder discussions.\nAbility to work with cross-functional teams that may include operators, engineers, software developers, modelers, data scientists, test personnel, subject matter experts, and government customers.\nStrong written and verbal communication skills.\nActive DoD Secret.\nAbility to obtain and maintain a U.S. Top Secret SCI clearance.\nPer the U.S. Government’s eligibility requirements, you must be a U.S Citizen to be considered for a security clearance.\nThis position requires a minimum of 4 days a week on-site.\nPreferred Qualifications:\nMaster’s degree and 8 years of experience in systems engineering, modeling and simulation, software engineering, computer science, or related disciplines.\nExperience using architecture/modeling tools: iGrafx, CAMEO, Rhapsody, or equivalent\nExperience using modeling languages and frameworks: SysML, BPMN, UAF/UAFML, or related methods\nExperience using simulation and mission analysis tools: Simulink, AFSIM, ITASE, NGTS, STL/Systems Tool Kit, OneSAF, or similar tools\nExperience leading mission engineering workstreams or small technical teams.\nExperience supporting Joint, Service, Combatant Command, acquisition, science and technology, prototyping, test, or experimentation organizations.\nExperience developing mission architectures that connect operational mission outcomes to system-level functions, capabilities, interfaces, dependencies, and performance parameters.\nExperience defining and applying MOSs, MOEs, MOPs, key performance parameters, operational measures, technical measures, and mission outcome metrics.\nExperience conducting tradespace analysis, gap analysis, sensitivity analysis, capability assessments, portfolio assessments, campaign analysis, operational analysis, or system of systems performance analysis.\nExperience with live, virtual, and constructive experimentation; test event planning; wargaming; red/blue/green force representations; operational scenario development; or data collection in operationally relevant venues.\nExperience evaluating kinetic and non-kinetic mission operations, including one or more of the following domains: air, maritime, land, space, cyber, electromagnetic spectrum operations, communications, command and control, fires, logistics, ISR, autonomy, or integrated air and missile defense.\nExperience with data pedigree, uncertainty quantification, model verification and validation, configuration management, and curation of reusable mission engineering artifacts.\nINCOSE ASEP, CSEP, or ESEP certification; DAWIA certification; test and evaluation certification; or relevant modeling and simulation certification.\nActive DoD Top Secret
