Experience: 14+ Years (with deep AWS architectural leadership)
Focus: On prem to AWS migration • Containerization • Consolidation • Lift & Shift • AWS Native Architecture
Role Overview
We are seeking a highly accomplished Senior AWS Architect with 14+ years of enterprise technology experience and proven expertise in leading complex on prem to AWS migration programs. The ideal candidate will architect scalable, secure, cost-optimized target environments on AWS, guide containerization & modernization initiatives, and drive migration strategies such as rehost (lift & shift), replatforming, refactoring, and application consolidation.
This role requires a blend of deep hands-on AWS knowledge, architectural leadership, stakeholder management, and the ability to articulate business value through AWS-native capabilities.
Key Responsibilities
1. AWS Target Architecture & Design
• Define end to end target-state architecture across compute, networking, security, storage, data, and application layers.
• Architect AWS landing zones, multi-account structures, and IAM strategy using AWS best practices.
• Recommend and architect AWS-native solutions (e.g., EKS, ECS, Lambda, RDS, DynamoDB, API Gateway, CloudWatch, S3, CloudFront, KMS, Control Tower).
• Ensure architectures are scalable, cost-efficient, secure, and operationally resilient.
2. On-Prem to AWS Migration Leadership
• Lead the architectural vision and execution strategy for migrating large application landscapes.
• Define migration patterns like lift & shift, lift & optimize, containerization, application consolidation, and modernization.
• Perform application discovery, dependency mapping, and wave planning.
• Provide architectural governance and oversight through design, build, test, migration, and cutover.
3. Containerization & Modernization Strategy
• Define and lead containerization journeys using Amazon ECS, EKS, Fargate, and container-focused CI/CD pipelines.
• Guide teams in refactoring monolithic applications into containerized or microservices architectures.
• Work closely with DevOps and platform teams to design secure, automated, and scalable container platforms on AWS.
4. Application & Infrastructure Consolidation
• Identify opportunities for consolidation of on-prem workloads while designing simplified, optimized AWS-based architectures.
• Rationalize applications, databases, and infrastructure footprints to reduce complexity and improve cost efficiency.
• Standardize patterns, templates, reusable modules, and architectural blueprints.
5. AWS Native Services Enablement & Value Realization
• Evaluate and recommend the right AWS-native services based on performance, cost, security, and business outcomes.
• Present detailed business cases showcasing benefits such as:
o Cost optimization (right-sizing, savings plans, S3 tiers, serverless models)
o Operational efficiency (automation, managed services, observability)
o Security enhancements (IAM, KMS, zero-trust designs)
o Scalability & reliability (autoscaling, global reach, high availability)
• Advise clients on cloud operating model transformation and best practices.
6. Technical Governance, Quality & Leadership
• Serve as the technical authority for all migration-related decisions.
• Conduct architecture reviews, ensure adherence to standards, and enforce security/compliance mandates.
• Mentor engineering and migration teams, enabling high-quality delivery aligned with enterprise objectives.
• Collaborate with program management on risk, cost, and timeline governance.
