This is a hands-on Senior Developer (Cloud) role within a managed services team, focused on supporting and optimising a serverless, microservices-based BFF (Backend-for-Frontend) platform. You will act as a key technical owner for critical Lambda, ECS, AppSync, API Gateway, and event-driven workloads, providing L2/L3 production support, troubleshooting complex issues, and driving stability, performance, and cost improvements across the AWS estate.
What you’ll do - Provide L2/L3 production support for serverless microservices and BFF (Backend-for-Frontend) layers on AWS, including incident management, problem resolution, and root cause analysis for Lambda, ECS, AppSync, API Gateway, SQS, and EventBridge workloads.
- Monitor and maintain the health, performance, and availability of critical services: respond to alerts, manage job schedules and event flows, and ensure timely resolution of failures to meet SLAs.
- Troubleshoot and resolve complex issues across the stack: Lambda timeouts and throttling, ECS task failures, API Gateway/AppSync errors, SQS backlogs, EventBridge rule failures, and integration issues with downstream systems.
- Maintain and optimise DynamoDB data stores for production workloads: investigate hot partitions, throttling, GSI/LSI performance issues, TTL behaviour, stream processing failures, and data consistency problems.
- Manage and secure VPC endpoints (gateway and interface) for DynamoDB, OpenSearch, and other services: troubleshoot connectivity issues, validate routing and DNS, and ensure private traffic remains within the VPC.
What we’re looking for - 5+ years’ professional software development experience, with at least 3+ years designing and operating production workloads on AWS.
- Deep hands-on expertise with AWS serverless and microservices services: Lambda, ECS/Fargate, API Gateway, AppSync, SQS/SNS, EventBridge, S3, CloudFront, WAF, Route 53, Certificate Manager, CloudWatch, X-Ray, ECR.
- Strong proficiency in at least one primary backend language (e.g., Node.js/TypeScript, Python, Java, or .NET) and experience building REST and GraphQL APIs at scale.
- Experience with Material UI (MUI) and modern front-end design practices, including responsive layouts, theming, and component customisation, with a solid understanding of web accessibility (WCAG 2.1 AA) principles such as keyboard navigation, focus management, ARIA attributes, colour contrast, and screen-reader compatibility.
- Advanced understanding of DynamoDB data modelling and access patterns (single-table design, GSIs/LSIs, TTL, streams, transactions) and experience integrating DynamoDB with Lambda, AppSync, and ECS.
- Experience working in Agile/DevOps teams using tools such as Jira, Confluence, GitHub/GitLab, and service management platforms (e.g., ServiceNow) for incident and change management.
- Relevant AWS certifications (e.g., AWS Certified Developer – Associate/Professional, AWS Certified Solutions Architect) or equivalent demonstrated expertise.
Why Join Us: - Deliver tangible business impact through operational excellence.
- Work with cutting-edge tools and AI-enabled platforms.
- Be part of a high-performing, client-obsessed team that values growth and innovation.
