London (Holborn), hybrid · [Permanent / Contract] · 12–15+ years

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

• Strong AWS architecture experience: ECS/EKS, Fargate, Lambda, API Gateway, S3, RDS, DynamoDB

• 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

Interested? Apply via [link] or send your CV to [email]. Please include a short note on the modernisation programme you're proudest of and the part you personally built.
