TQUKE0857_5345 - Enterprise Architect

We are seeking a highly experienced Enterprise Architect to lead and govern large-scale on-premises to AWS migration programs. The ideal candidate will drive end-to-end architecture, ensure enterprise tools and platforms integrate seamlessly into the target AWS environment, and provide strong oversight on risk mitigation, cost optimization, delivery timelines, and technical quality. This is a strategic role requiring deep technical expertise, leadership, and the ability to collaborate across engineering, security, compliance, infrastructure, and business teams.

Key Responsibilities

1. Cloud Migration Strategy & Architecture

· Define the overall cloud migration blueprint, including landing zone architecture, application migration patterns (rehost, replatform, refactor), and modernization opportunities.

· Lead current-state assessment and target-state AWS architecture definition across compute, storage, networking, security, identity, data, and application domains.

· Select appropriate AWS services aligned to enterprise standards, scalability needs, security controls, and cost expectations.

2. Delivery Leadership for On-Prem to AWS Migration

· Own delivery governance for migration execution, ensuring adherence to architecture, methodology, and organizational best practices.

· Guide migration teams on workload prioritization, dependency mapping, wave planning, and cutover strategies.

· Provide architectural oversight during build, testing, deployment, and hypercare phases.

3. Enterprise Tool & Platform Integration

· Ensure seamless integration of enterprise tools within the AWS target environment, including:

o Monitoring (e.g., Datadog, CloudWatch, AppDynamics)

o Security tooling (SIEM/SOAR, vulnerability scanners, identity systems)

o ITSM/ITOM platforms (ServiceNow, CMDB integrations)

o DevSecOps pipelines and enterprise CI/CD frameworks

· Define integration patterns, interface contracts, and compliance controls for all cross-platform interactions.

4. Risk Management & Governance

· Establish and maintain a migration risk register, covering technical, security, compliance, timeline, and operational risks.

· Drive proactive mitigation strategies and technical solutions to reduce migration complexity and cutover risks.

· Ensure architectural decisions meet enterprise risk, security, and regulatory requirements.

5. Financial Governance & Cost Optimization

· Develop cost models and TCO calculations for AWS target environments.

· Ensure design decisions minimize unnecessary spend through rightsizing, architectural efficiencies, and use of AWS cost-optimization features.

· Collaborate with FinOps teams to track usage patterns and optimize ongoing run-rate.

6. Timeline, Program, and Stakeholder Management

· Partner with program management teams to define realistic migration timelines, milestones, and success measures.

· Ensure cross-functional alignment between engineering, security, infra, networking, and business stakeholders.

· Present architectural decisions, risks, and progress updates to senior leadership and steering committees.
