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.

Required Skills & Experience

Technical Expertise

· 14+ years of enterprise IT experience with extensive AWS cloud architecture expertise.

· Strong hands-on skills across AWS compute, networking (VPC, TGW), IAM, storage, container platforms, and automation tools.

· Deep experience with:

o EC2, Lambda, ECS/EKS/Fargate, RDS/Aurora/DynamoDB, S3, CloudFront, Route53

o Designing secure IAM/KMS strategies

o Architecting multi-account environments using Control Tower / Organizations

· Expert-level understanding of migration tooling (CloudEndure, DMS, SMS) and modernization frameworks.

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).

Leadership & Communication

· Ability to influence senior stakeholders and articulate architecture decisions.

· Strong problem-solving, documentation, and presentation skills.

· Experience collaborating across security, compliance, DevOps, infrastructure, and application teams.

Preferred Qualifications

· AWS Certified Solutions Architect – Professional

· AWS DevOps Engineer / Security Specialty certifications

· Experience with FinOps, cost modeling, and optimization frameworks

· Experience in multi-cloud environments (nice-to-have)
