Job Description

Job Title: Senior Enterprise Architect

Overview
The Enterprise Architecture team defines, documents, and advances the enterprise IT environment across networking, infrastructure, applications, cloud, and cybersecurity. We support mission-critical IT and cybersecurity initiatives across 54 states and territories in alignment with Army, DISA, and DoD policies, ensuring a secure, scalable, and modern environment.

As a Senior Enterprise Architect, you will be a seasoned technical contributor. You will drive architecture development and modernization, provide senior-level technical guidance, and help ensure that solutions are consistent, secure, and aligned with mission and business objectives. While not a formal team lead, you will be relied on for deep expertise and sound architectural judgment.

Meaningful Work and Your Impact

In this role, you will:

• Contribute to the development and refinement of enterprise architectures, including current (“as-is”) and target (“to-be”) states across infrastructure, applications, data, and security.

• Support the creation and maintenance of enterprise architecture roadmaps that guide modernization, cloud adoption, cybersecurity, and technology standardization.

• Provide senior-level technical insight and recommendations to architects, engineers, program staff, and cybersecurity teams on architecture options and tradeoffs.

• Capture, document, and maintain the enterprise IT environment, including models, diagrams, inventories, and reference architectures for 54 states and territories.

• Apply and reinforce architecture principles, standards, and patterns that promote interoperability, security, and reuse across programs.

• Assess existing systems and proposed solutions for alignment with enterprise architecture, security requirements, performance needs, and operational constraints.

• Evaluate emerging technologies, tools, and industry trends and contribute to assessments and recommendations for their applicability.

• Translate complex technical architectures into clear diagrams, models, and documentation for technical and non-technical audiences.

• Collaborate with cybersecurity teams to ensure architectures support zero trust principles, RMF, and DoD/Army/DISA security policies.

• Participate in technical exchange meetings, design reviews, and architecture boards, providing expert input and constructive feedback.

• Identify architecture gaps, dependencies, and risks, and propose improvements or mitigations.

• Support improvements in architecture documentation, modeling practices, data quality, and configuration management.

• Informally mentor and support junior and mid-level team members, sharing best practices and lessons learned.
