6months + with possible extension

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).

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.

Preferred Qualifications

• AWS Certified Solutions Architect – Professional
• AWS DevOps Engineer / Security Specialty certifications
