Senior Enterprise Architect (Digital Engineering)

Modern Technology Solutions, Inc. (MTSI) is hiring a Senior Enterprise Architect to work in Springfield, VA. Qualified candidates must be U.S. citizens with an active TS/SCI clearance and be eligible to obtain a CI Poly.

Responsibilities: • Define and evolve the architecture framework underpinning a Digital Engineering Ecosystem (DEE) supporting our Intel customer. • Owns the technical vision for how enterprise architecture, Model Based Systems Engineering (MBSE), and business intelligence layers integrate into a single governed, model-driven digital enterprise. • Sets MBSE standards, lifecycle traceability approaches, and digital thread strategy, and works hands-on in high-impact areas to ensure the architecture remains open, standards-based, and vendor-neutral. • Leads strategic-level meetings with government stakeholders and serves as a primary point of contact for technical and management issues of strategic importance to the program. • Define and maintain the overall architecture framework, MBSE standards, and lifecycle traceability approach for the DEE, using UAF for enterprise-level modeling and SysML (v1 and emerging v2) for system-level semantics. • Lead current-state capture and evaluation of the enterprise Digital Ecosystem — capabilities, IT assets, services, data types, interfaces, and data repositories — captured in UAF/SysML models as the initial enterprise baseline. • Conduct tool trade studies and produce Architecture Decision Records (ADRs), weighing cost, security, license tier, cloud-native compatibility, interoperability, vendor agnosticism, and sustainment tail. • Establish Model Based Enterprise Architecture (MBEA) practices enabling 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. • Own and oversee all program governance activities, including model integrity standards, data consistency policies, and lifecycle alignment across the Digital Engineering, Data Layer, Cloud Native Platform, and Enterprise Architecture & BI swimlanes, ensuring cyber and security practices are integrated into each engineering discipline rather than siloed.

Required Qualifications: • 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. • Demonstrated 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. • Possess deep familiarity with UAF and SysML modeling and the ability to lead current-state assessments and tool trade studies for a large, multi-organization enterprise.

Desired Qualifications: • Experience supporting 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.

Clearance Requirements: • Must be a U.S. citizen with an active TS/SCI clearance and have the ability to pass a CI polygraph within 30 days.

The pay range for this position is $130,000 to $190,000/year; however, base pay offered may vary depending on established government contract ranges, job-related knowledge, skills, and experience, and other factors. MTSI also offers a full range of medical, financial, and other benefits, dependent on the position offered. Base pay information is based on market location.
