AWS Modernization Specialist

Role & responsibilities

We are seeking a skilled and experienced AWS Modernization Specialist to design and execute application modernization strategies, transforming legacy systems into cloud-native microservices and event-driven architectures on AWS.

The ideal candidate will have hands-on experience in application modernization, microservices design with ECS/EKS, event-driven architectures using EventBridge and Step Functions, and service mesh patterns on AWS.

Key Responsibilities

• Assess legacy frameworks and platforms for modernization readiness and strategy.
• Design microservices architectures for monolith decomposition using strangler fig and branch-by-abstraction patterns.
• Execute monolith to microservices decomposition including database separation and bounded context identification.
• Develop REST APIs and serverless services on AWS Lambda using SAM and API Gateway.
• Implement event-driven design patterns using SQS, SNS, EventBridge, and Step Functions (visual workflows with parallel processing and error handling).
• Design and execute database decomposition and migration strategies.
• Implement containerization and orchestration using Docker, Amazon ECS/EKS, and Fargate.
• Configure service discovery using AWS Cloud Map for dynamically changing microservices.
• Provide technical guidance to associates on modernization best practices.
• Collaborate with architecture and DevOps teams to ensure smooth transitions.

Required Qualifications

• Bachelor's degree in Computer Science, Engineering, or related field.
• 5+ years of experience in software engineering.
• 3+ years of hands-on AWS experience in modernization or transformation.
• Strong proficiency in microservices architecture design and implementation.
• Hands-on experience with monolith decomposition (strangler fig, branch-by-abstraction) and database separation.
• Strong backend development skills with Java, Python, Node.js, or equivalent.
• Experience designing and implementing REST APIs on Lambda using SAM and API Gateway.
• Experience with event-driven architectures (SQS, SNS, EventBridge, Step Functions).
• Proficiency with containerization and orchestration (Docker, ECS/EKS, Fargate).
• Understanding of database modernization patterns, DMS, and SCT.
• Familiarity with service discovery (Cloud Map) and service mesh (App Mesh) concepts.
• Strong communication skills and ability to articulate technical decisions.
• Knowledge of Agile Methodology and Practices.

Nice to Have

• AWS Developer Associate or Solutions Architect Associate certification.
• Experience with AI tools in development lifecycles (GitHub CoPilot, Cursor, Amazon Q Developer).
• DevOps experience (CI/CD pipelines using CodePipeline, GitHub Actions).
• Experience with Infrastructure as Code (Terraform, CloudFormation, CDK).
• Familiarity with strangler fig, branch-by-abstraction, and other incremental migration patterns.
• Experience with observability tools (X-Ray, Container Insights).
