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.
1. 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.
1. 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.
1. 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.
1. 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
Migration & Modernization Expertise
* Proven experience leading end-to-end large-scale migration programs.
* Strong understanding of application architectures (monolith, microservices, distributed systems).
* Skilled in designing containerization & orchestration strategies (Docker, Kubernetes, EKS).
