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
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.
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.
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.
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.
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:
Cost optimization (right-sizing, savings plans, S3 tiers, serverless models)
Operational efficiency (automation, managed services, observability)
Security enhancements (IAM, KMS, zero-trust designs)
Scalability & reliability (autoscaling, global reach, high availability)
Advise clients on cloud operating model transformation and best practices.
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.
