[Hiring] Senior Systems Engineer @Leidos

Role 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:

• Characterize missions and develop digital mission architectures composed of mission threads and mission engineering threads in UAF.
• 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.
• Work closely with Coast Guard leadership, requirements owners, operational planners, program managers, enterprise architects, operations analysts, developers, cybersecurity teams, and mission stakeholders.

Primary Responsibilities

• Lead and support mission engineering studies following the MEG v2.0 methodology.
• Develop and maintain digital mission architectures in UAF/UAFML.
• Apply the UAF grid across various domains to produce coherent, traceable views.
• Define mission metrics and maintain traceability from desired mission outcomes.
• Build and maintain enterprise, mission, and system architecture models in CATIA Magic / Cameo.
• Develop and execute mission-level modeling and simulation using tools such as AFSIM, MATLAB/Simulink, or Ansys STK.
• Connect UAF/SysML architecture models, engineering analyses, and operational simulations into an authoritative, integrated analytical environment.
• Develop mission engineering and systems engineering products.
• Support structured, iterative experimentation, prototyping, and wargaming activities.
• Support alignment and interoperability of Coast Guard mission architectures.
• Establish and maintain UAF modeling standards, style guides, model governance, and configuration management practices.
• Present model- and simulation-derived findings to technical and non-technical audiences.
• Support technical roadmaps, mission engineering and digital engineering ecosystem strategies.

Qualifications

• Bachelor’s degree in Systems Engineering, Engineering, Computer Science, Operations Research, or related discipline and 8–10 years of related experience, or 6–10 years with a Master’s degree.
• Demonstrated experience developing enterprise and mission architectures in UAF/UAFML.
• Demonstrated experience conducting or directly supporting mission engineering studies.
• Working knowledge of the DoW Mission Engineering Guide v2.0, DoWI 5000.88, and DoWI 5000.97.
• Modeling and simulation experience using tools such as AFSIM, MATLAB/Simulink, or Ansys STK.
• OMG Certified Systems Modeling Professional (OCSMP) Model Builder.
• Experience supporting complex federal IT, systems engineering, or modernization programs.
• Strong written and verbal communication skills.
• U.S. Citizenship required; ability to obtain and maintain a DHS Public Trust.

Preferred Qualifications

• OMG Certified UAF Professional (OCUP or UAF certification).
• Experience integrating UAF/SysML mission architectures with AFSIM or Ansys STK scenarios.
• Experience supporting OUSD(R&E) mission engineering activities.
• Familiarity with SysML v2, its API and services.
• Proficiency in Python or MATLAB for simulation automation.
• Experience supporting U.S. Coast Guard, DHS, or DoW mission engineering programs.
• INCOSE CSEP/ESEP, DAU or Service mission engineering coursework.
