About The Position

Modern Technology Solutions, Inc. (MTSI) is hiring a Lead Model Based Systems Engineer (MBSE)/Digital Engineer to work in Springfield, VA or St. Louis, MO. Qualified candidates must be U.S. citizens with an active TS/SCI clearance and be eligible to obtain a CI Poly. This role involves serving as a senior technical advisor to the NGA Chief Architect, providing hands-on leadership for modeling, Digital Thread strategy, lifecycle traceability, and ecosystem integration. The position aims to engineer the evolution from fragmented tools and disconnected data towards a unified, model-driven ecosystem anchored by an enterprise authoritative data source, enabling decision-grade engineering and mission operations. The Lead MBSE/Digital Engineer will guide MBSE/UAF/SysML modeling efforts, coordinate mission engineering threads, and shape the architectural and data integration backbone for NGA’s enterprise-level Digital Twin. This role requires leading a team of MBSE engineers and collaborating deeply with various stakeholders including the Enterprise Architect, data Architect, Platform/Cloud engineers, mission engagement leads, cyber team, governance stakeholders, and vendor partners. The individual will be instrumental in building NGA’s EA Digital Twin capability, modeling the future-state enterprise, and delivering the unified Digital Engineering environment sought by the IC and DoW. The role operates at a strategic level while remaining deeply technical, serving as a critical force multiplier for the Chief Architect and NGA’s Digital Transformation journey.

Nice To Haves

Experience with UAF and early adoption of SysMLv2 (including textual modeling tools such as SysIDE).
Experience integrating MBSE tools with Requirements Management Tools, MS&A, CAD/CAE and Digital Thread technologies (Syndeia, ModelCenter, etc.).
Prior trusted advisor experience supporting senior government technical leadership.
Ability to automate model and data collection to assess DEE current state and quantify ROI relative to mission outcomes.
Broad familiarity with the larger DEE tech stack (requirements tools, MS&A, DevSecOps platforms, EA/BI systems, data fabric technologies).
Experience with data modeling and ontologies.
Self-starter that can automate data gathering to assess current state of a Digital Ecosystem and to assess ROI of assets vs mission outcomes.
Broader understanding and experience with larger DEE tech stack including requirements management, MS&A, SDLC/DevSecOps, EA tools, data fabric.

Responsibilities

Serve as a senior technical advisor to the NGA Chief Architect and provide hands-on leadership for the modeling, Digital Thread strategy, lifecycle traceability and ecosystem integration that underpin the DEE.
Help engineer the evolution from fragmented tools and disconnected data toward a unified, model-driven ecosystem anchored by an enterprise authoritative data source, enabling decision-grade engineering and mission operations.
Guide MBSE/UAF/SysML modeling efforts, coordinate mission engineering threads, and directly shape the architectural and data integration backbone for NGA’s enterprise-level Digital Twin.
Leads a team of MBSE engineers and collaborates deeply with the Enterprise Architect, data Architect, Platform/Cloud engineers, mission engagement leads, cyber team, governance stakeholders, and vendor partners.
Be instrumental in building NGA’s EA Digital Twin capability, modeling the future-state enterprise, and delivering the unified Digital Engineering environment the IC and DoW have sought for years.
Operate at the strategic level while remaining deeply technical, becoming a critical force multiplier for the Chief Architect and for NGA’s Digital Transformation journey.
Serve as the enterprise lead for Digital Engineering and MBSE, driving standards, governance, and model centric transformation across NGA.
Lead and mentor a high-performing team of DE/MBSE engineers to advance modeling, integration, and ecosystem maturation throughout the organization.
Partner seamlessly with the tech lead, enterprise architect, data engineers, cloud/platform teams, cyber professionals, and mission engagement leads to deliver cohesive enterprise outcomes.
Advise the Chief Architect and senior leadership with continuous assessments, insights, and recommendations that strengthen DE/MBSE capability and accelerate digital transformation agency-wide.
Model end-to-end enterprise solutions — spanning capabilities, services, APIs, workflows, and data models — to architect a future-ready, resilient DEE.
Collaborate with platform and data engineers to deploy applications, build Digital Threads, and automate pipelines that unify authoritative data sources and deliver high-fidelity engineering insights.
Act as a key technical liaison with industry partners, leading technical exchanges, reconciling competing architecture, and driving consensus toward integrated, mission-focused solutions.
