This role will work closely with Coast Guard stakeholders, enterprise architects, systems engineers, business process teams, data analysts, and program leadership to develop modeling approaches, evaluate tools and platforms, and support implementation planning for digital engineering capabilities within the CGOne environment.

This position requires strong analytical, technical, and stakeholder engagement skills, with the ability to translate operational requirements into scalable digital models, simulation frameworks, and engineering recommendations supporting enterprise modernization efforts.

Primary Responsibilities

Support development and execution of Digital Transformation and Digital Engineering implementation plans for CG-TECH-TRT/DME.

+ Develop and maintain mission, process, operational, and system models supporting Coast Guard transformation initiatives, using SysML and UAF/UAFML modeling languages.

+ Create conceptual, logical, and physical data models using SysML/UAFML to represent enterprise information, data flows, and system relationships.

+ Support data architecture development, including definition of data standards, data structures, integration patterns, and traceability across mission, operational, and system domains.

+ Conduct modeling and simulation analyses to support operational planning, capability assessments, and modernization initiatives.

+ Support evaluation and selection of digital engineering, modeling, and simulation tools and platforms suitable for the CGOne environment.

+ Assist in the development of enterprise architecture artifacts, system interaction models, digital workflows, and mission thread analyses.

+ Collaborate with business analysts and process improvement teams to translate operational workflows into simulation and modeling use cases.

+ Support feasibility assessments, pilot planning, and proof-of-concept activities for digital transformation initiatives.

+ Develop dashboards, performance metrics, and analytical products supporting program governance and executive decision-making.

+ Support stakeholder engagement sessions, workshops, technical exchanges, and executive briefings with Coast Guard leadership.

+ Contribute to automation portfolio planning, digital transformation governance, and continuous improvement initiatives.

+ Maintain documentation repositories, technical artifacts, modeling standards, data models, and lessons learned.

+ Coordinate with cybersecurity, cloud, data, and engineering teams to ensure solutions align with enterprise architecture, data architecture, and security requirements.

Basic Qualifications

+ Bachelor's degree in Systems Engineering, Engineering, Operations Research, Computer Science, Modeling & Simulation, Data Science, or a related field, and 6-10yrs of experience with a master's; additional experience may be considered in lieu of a degree.

+ Experience supporting federal government, DHS, or Coast Guard programs.

+

Experience with digital engineering, systems modeling, operational analysis, or simulation environments.

+ Experience developing enterprise architecture artifacts, process models, mission models, data models, data architecture, and systems integration documentation.

+ Strong understanding of data modeling and data architecture concepts and applications.

+ Experience facilitating stakeholder engagements and translating mission requirements into technical solutions.

+ Ability to communicate technical concepts to both technical and non-technical audiences.

+ U.S. Citizenship required.

+ Ability to obtain and maintain a DHS Public Trust.

Preferred Qualifications

+ Experience supporting U.S. Coast Guard mission systems or DHS enterprise initiatives.

+

Experience with MBSE tools such as Cameo, Magic Draw, Sparx EA, or similar platforms.

+

Experience with modeling frameworks and languages such as DoDAF, UAF, SysML, IDEF0, ERDs or UML.

+ Experience supporting cloud-enabled digital engineering environments.

+ Knowledge of automation technologies, AI/ML integration, or data analytics platforms.
