: Senior AWS Architect (14+ Years Experience)
Role: Senior AWS Architect
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:

• 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.

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:

• EC2, Lambda, ECS/EKS/Fargate, RDS/Aurora/DynamoDB, S3, CloudFront, Route53
• Designing secure IAM/KMS strategies
• 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)

Success Measures

• High-quality, on-time migration delivery with zero major defects.
• Demonstrated use of AWS-native services delivering measurable cost, performance, and operational benefits.
• Stable, secure, scalable AWS target environment aligned to best practices.
• Strong stakeholder satisfaction and clear architectural governance.
