Strategic ACI; Springfield (VA); On-site; USD 180,000 - 240,000; Full time

Job summary

Strategic ACI seeks a Senior Enterprise Architect to shape the architecture framework for a Digital Engineering Ecosystem supporting NGA. You will own MBSE standards, MBSE/MBEA alignment, and a model-driven enterprise across architecture, data, and BI layers.

You’ll lead high-impact, government-facing discussions, craft ADRs, and ensure open, vendor-neutral solutions while driving cyber and security considerations across disciplines.

Qualifications

• Active TS clearance, SCI eligibility and CI polygraph within 30 days.
• Bachelor's degree in Systems Engineering, Computer Science, or related field, or equivalent experience.
• 15+ years of enterprise architecture or systems engineering experience.
• Hands-on expertise with UAF and SysML modeling using MBSE tools such as Cameo/Teamwork Cloud.

Responsibilities

• Define and maintain the architecture framework, MBSE standards, and lifecycle traceability for the Digital Engineering Ecosystem.
• Lead current-state capture and evaluation of the enterprise Digital Ecosystem using UAF/SysML models as baseline.
• Conduct tool trade studies and produce Architecture Decision Records (ADRs).
• Establish Model Based Enterprise Architecture (MBEA) practices for capabilities, processes, systems, services, and data.
• Drive interoperability between MBSE and Modeling, Simulation & Analysis tools to link capabilities across the lifecycle.
• Author and evolve current-state models, capability maturity assessments, and architecture documentation.
• Partner with leadership, engineering, and data teams to govern models, data, and ontologies.
• Oversee governance activities including model integrity, data consistency, and security across domains.

Job description

Strategic ACI is seeking a Senior Enterprise Architect to define and evolve the architecture framework underpinning a Digital Engineering Ecosystem (DEE) supporting NGA. This role 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.

The Enterprise Architect 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. This role requires 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. As a senior subject matter expert, this role 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.

Salary will be commensurate within the advertised range, based on applicable qualifications.

Responsibilities:

• 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.

Qualifications:

Required:

• Active TS clearance, with SCI eligibility and the ability to pass a CI polygraph within 30 days.
• 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.

Desired:

• Experience supporting NGA, DoD, or Intelligence Community enterprise architecture 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.
