The Role:
This role is for an experienced IT Application Developer responsible for designing, building, and delivering high quality, cloud native applications. You will lead end to end development using TypeScript/JavaScript, Node.js, and modern API/microservice architectures, making sound technical and architectural decisions throughout the delivery lifecycle.
You will develop scalable, resilient applications using AWS services such as ECS, ECR, S3, CloudWatch, Kinesis Firehose, IAM, and SQS, while applying best practice engineering approaches including Test Driven Development, unit/integration/contract testing, and containerised application design. The role also contributes to API standards and governance, including work with Apigee, ensuring secure, consistent, and maintainable service designs
