Position Summary

The MTA is seeking a highly skilled Senior Enterprise Architect with deep expertise in application modernization, cloud-native design, and enterprise application portfolio management. This role focuses on hands‑on architecture execution—developing modern solutions, guiding cloud migrations, creating reusable standards, and partnering with engineering teams to modernize and streamline the application landscape. The architect will work primarily on both AWS, Azure and hybrid environments, supporting modernization roadmaps, technical debt reduction, and application lifecycle governance.

Key Responsibilities

1. Architecture Standards, Patterns & Modernization Frameworks

• Develop, publish, and maintain application and integration architecture standards.

• Create reusable modernization patterns (microservices, APIs, event-driven, containerization).

• Contribute to reference architectures and ensure consistency across engineering teams.

• Support solution architects and delivery teams in applying approved standards.

2. Application Modernization Execution

• Design modernization paths for legacy applications: rehost, replatform, refactor, retire.

• Architect cloud‑native and hybrid solutions primarily on Azure (AKS, Functions, APIM, PaaS).

• Work hands‑on with engineering teams during design, PoCs, and early build phases.

• Guide workload decomposition, domain boundaries, service design, and modernization roadmaps.

3. Cloud Architecture & Platform Enablement

• Build and evolve Azure landing zone components and cloud governance configurations.

• Define infrastructure, integration, API, and data patterns for cloud adoption.

• Support hybrid cloud integrations with Azure, AWS, and GCP where applicable.

• Evaluate new cloud capabilities (AI, observability, DevSecOps, automation tools).

4. Application Portfolio Management & Rationalization

• Perform architecture‑led assessments using frameworks such as TIME or 6R.

• Identify consolidation, migration, and retirement opportunities to reduce redundancy.

• Partner with ServiceNow APM/CMDB to ensure accurate application inventory and lifecycle data.

• Develop architecture metrics and dashboards supporting modernization progress.

5. Technical Debt Analysis & Remediation Support

• Maintain application‑level technical debt insights across the portfolio.

• Partner with product teams to prioritize remediation aligned with risk, business value, and modernization sequencing.

• Provide guidance on remediation strategies, patterns, and target-state architecture alignment.

6. Infrastructure as Code (IaC) & Automation Enablement

• Contribute to IaC templates using Terraform, Bicep/ARM, or Pulumi.

• Support CI/CD pipeline architecture using GitHub Actions, GitLab, or Jenkins.

• Partner with DevOps teams to apply automation and configuration management practices (Ansible, Chef, Puppet).

7. Security, Compliance & Optimization

• Apply cloud security best practices and integrate IAM/RBAC, network security, and Key Vault usage into designs.

• Ensure alignment with CIS, NIST, ISO 27001, and MTA security requirements.

• Support cloud cost optimization efforts using Azure Advisor and FinOps guidelines.

8. Cross‑Functional Collaboration & Communication

• Work closely with DevOps, Networking, Cybersecurity, Infrastructure, Finance, and Procurement teams.

• Translate complex modernization concepts into clear, actionable guidance for business and technical stakeholders.

• Participate in strategic planning, cloud strategy working sessions, and solution design workshops.
