AWS Full-Stack Developers

This is a hands-on opportunity to work with modern AWS technologies and AI-assisted development tools, helping establish a repeatable migration approach for approximately 30 further Legacy systems.

The team is hiring across two areas: application development and cloud infrastructure/data migration. Both developers will work across the full stack., * Build serverless applications using AWS Lambda, API Gateway, S3, EventBridge and SQS.

• Reverse-engineer Legacy code and migrate business logic into modern applications.
• Develop modern Front End applications to replace Legacy OpenROAD interfaces.
• Migrate Ingres databases to Aurora PostgreSQL, including schema conversion and data reconciliation.
• Build secure AWS infrastructure using VPCs, networking and identity services.
• Implement Infrastructure as Code using Terraform and develop CI/CD pipelines.
• Use AI-assisted tools such as AWS Transform and Kiro to accelerate code analysis and migration.
• Develop automated testing to ensure the new platform matches existing system behaviour.

• Strong commercial AWS development experience, particularly serverless architectures.
• Full-stack development using a modern Front End framework and TypeScript or Python.
• Hands-on experience with Lambda, API Gateway, S3, EventBridge and SQS.
• Relational database migration experience, ideally PostgreSQL or Aurora.
• Experience using AI-assisted development tools for code analysis or modernisation.
• Terraform/OpenTofu and CI/CD experience.
• Understanding of AWS networking, security and private cloud environments.
• Strong automated testing and application validation experience.

Desirable

• Experience with Ingres, OpenROAD or Legacy 4GL technologies.

• Aurora PostgreSQL and RDS Proxy experience.
• Previous public-sector or regulated industry experience.
