NCONS Talent Solutions is looking for a hands‑on AWS Technology Lead to take a monolithic Java application running on EC2 and rebuild it as an AWS‑native solution.

What you'll do

Analyse the existing monolith (code, dependencies, data) using Kiro and other AI-assisted tools
Design the target architecture: microservices on ECS/Fargate or EKS, Lambda, API Gateway, event-driven services (SQS, SNS, EventBridge)
Plan a phased migration (strangler fig pattern) with no disruption to the live system
Lead database migration and tuning across Aurora PostgreSQL, RDS and DynamoDB
Build CI/CD and infrastructure as code with Jenkins or GitHub Actions, Docker and Terraform/CloudFormation
Write and review Java, Spring Boot and TypeScript code
Run client workshops, present design decisions and mentor engineers across distributed teams

What you'll bring

Proven lead role on a Java monolith to AWS microservices modernisation, beyond lift-and-shift
Recent hands‑on Java / Spring Boot, plus TypeScript or Python
Hands‑on database skills: data modelling, SQL tuning, migration, backup and recovery
Terraform or CloudFormation, CI/CD, automated testing and security scanning
Clear communication with technical and business stakeholders
