Senior Systems Engineer – Mission Engineering, Modeling & Simulation

Description

Leidos’s Digital is seeking a Senior Systems Engineer – Mission Engineering, Modeling & Simulation.

The Senior Systems Engineer will support the U.S. Coast Guard CG-TECH-DME organization in executing enterprise digital transformation, digital engineering, and mission engineering (ME) initiatives supporting Force Design 2028 objectives. The role provides technical leadership in mission engineering, model-based systems engineering (MBSE), and mission-level modeling and simulation (M&S), applying the methodology of the DoW Mission Engineering Guide (MEG) v2.0 and the digital engineering practices established in DoW Instruction 5000.97 to Coast Guard missions.

The Unified Architecture Framework (UAF) and its modeling language, UAFML, together with SysML, are the primary languages for this position: the Senior Systems Engineer will characterize missions, develop digital mission architectures composed of mission threads and mission engineering threads in UAF, and execute threat-informed, quantitative analyses to evaluate operational concepts, assess capability gaps and candidate solutions, inform acquisition, modernization, and resourcing decisions, and quantify mission effectiveness across Coast Guard mission systems, platforms, and systems of systems.

This individual will work closely with Coast Guard leadership, requirements owners, operational planners, program managers, enterprise architects, operations analysts, developers, cybersecurity teams, and mission stakeholders.

• Lead and support mission engineering studies following the MEG v2.0 methodology: define the mission problem statement, characterize the mission (scenario, vignettes, threats, environment, assumptions, and constraints), and scope each analysis to the acquisition, modernization, or resourcing decision it is intended to inform.

• Develop and maintain digital mission architectures in UAF/UAFML, including mission threads (MTs) that capture the end-to-end sequence of operational activities and mission engineering threads (METs) that allocate systems, platforms, organizations, and information exchanges to those activities, as baseline and alternative mission architectures.

• Apply the UAF grid across the Strategic, Operational, Services, Resources, Personnel, Security, Projects, and Standards domains to produce coherent, traceable views from capability and mission objectives through operational activities to resource and system realization, and generate DoDAF-conform ant views from the UAF model where required by DHS, DoW, or Joint stakeholders.

• Define mission metrics, including measures of effectiveness (MOEs), measures of performance (MOPs), and measures of suitability (MOSs), and maintain traceability from desired mission outcomes through UAF capabilities and operational activities to SysML system requirements and design parameters.

• Build and maintain enterprise, mission, and system architecture models in CATIA Magic / Cameo (Enterprise Architecture and Systems Modeler) using UAFML and SysML, including model organization, profiles and customizations, validation suites, model queries and reports, and trade studies, and support transition planning toward SysML v2.

• Develop and execute mission-level modeling and simulation using tools such as AFSIM, MATLAB/Simulink, or Ansys STK to assess baseline and alternative mission architectures, quantify capability gaps, and compare candidate materiel and non-materiel solutions against mission metrics.

• Connect UAF/SysML architecture models, engineering analyses, and operational simulations into an authoritative, integrated analytical environment (digital thread) supporting decision-making across the lifecycle, and verify, validate, and document models and…
