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.

This is a builder-leader role. You will design the target architecture, write and review code, and lead the engineering team and client conversations from start to finish.

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

Nice to have

• Experience with Kiro, Amazon Q Developer or other AI coding tools
• AWS Certified Solutions Architect or DevOps Engineer – Professional
• Background in logistics, retail, financial services or manufacturing

You must have the right to work in the UK.
