Senior Enterprise Architect (Digital Engineering)

Modern Technology Solutions, Inc. (MTSI) is seeking a Senior Enterprise Architect for locations in Springfield, VA or St. Louis, MO. U.S. citizenship, an active TS/SCI clearance, and eligibility to obtain a CI Poly are required.

About the Role

This position defines and evolves the architecture framework for a Digital Engineering Ecosystem (DEE) supporting NGA. The role owns the technical vision for integrating enterprise architecture, Model Based Systems Engineering (MBSE), and business intelligence into a governed, model-driven digital enterprise.

Responsibilities

• Set MBSE standards, lifecycle traceability approaches, and digital thread strategy, ensuring the architecture remains open, standards-based, and vendor-neutral.
• Lead strategic-level meetings with government stakeholders as the primary point of contact for technical and management issues.
• Define and maintain the overall architecture framework, MBSE standards, and lifecycle traceability using UAF for enterprise-level modeling and SysML (v1 and emerging v2) for system-level semantics.
• Capture and evaluate the current state of the enterprise Digital Ecosystem, including capabilities, IT assets, services, data types, interfaces, and data repositories, documented in UAF/SysML models.
• Conduct tool trade studies and produce Architecture Decision Records (ADRs), evaluating cost, security, license tier, cloud-native compatibility, interoperability, vendor agnosticism, and sustainment tail.
• Establish Model Based Enterprise Architecture (MBEA) practices for enterprise-wide modeling of capabilities, processes, systems, services, and data, extending into MBSE-driven Digital Twins.
• Drive interoperability between MBSE and Modeling, Simulation & Analysis (MS&A) tools to establish Digital Threads linking capabilities across the lifecycle.
• Author and evolve enterprise current-state models, capability maturity assessments, and supporting architecture/requirements documentation.
• Partner with program leadership, engineering, and data architecture teams to align governance of enterprise architecture models, data models, metadata models, schemas, and ontology.
• Oversee program governance activities, including model integrity standards, data consistency policies, and lifecycle alignment across Digital Engineering, Data Layer, Cloud Native Platform, and Enterprise Architecture & BI swimlanes, integrating cyber and security practices into each engineering discipline.

Requirements

• Bachelor’s degree in Systems Engineering, Computer Science, or a related field, or additional relevant experience in lieu of a degree.
• 15+ years of enterprise architecture or systems engineering experience.
• Hands-on expertise with UAF and SysML modeling, including tools such as Cameo Enterprise Architect, Teamwork Cloud, or comparable MBSE platforms.
• Experience developing Architecture Decision Records, tool trade studies, and capability/gap analyses for large, multi-organization enterprises.
• Strong understanding of Model Based Systems Engineering (MBSE) and Model Based Enterprise Architecture (MBEA) principles and their application to Digital Twins.
• Deep familiarity with UAF and SysML modeling, including leading current-state assessments and tool trade studies for large enterprises.
• U.S. citizenship with an active TS/SCI clearance and ability to pass a CI polygraph within 30 days.

Qualifications (Desired)

• Experience supporting NGA, DoD, or Intelligence Community enterprise data or digital engineering programs.
• Familiarity with SysMLv2 and associated textual modeling/validation tooling (e.g., VS Code with SysIDE).
• Experience with requirements management tools such as IBM DOORS Next and traceability/integration tools such as Syndeia.
• Exposure to Modeling, Simulation & Analysis (MS&A) tools such as AFSIM, STK, or Unreal Engine, and geospatial tools such as ArcGIS.
• INCOSE CSEP/ESEP or equivalent systems engineering certification.

Pay

The pay range for this position is $130,000 to $190,000 per year, with base pay varying based on job-related knowledge, skills, experience, and market location.

Benefits

MTSI offers a full range of medical, financial, and other benefits, dependent on the position.
