Role Summary We are looking for a highly hands-on AWS Application Developer with deep TypeScript expertise and strong serverless/event-driven engineering skills. This role requires building and operating production-grade solutions using AWS Lambda, EventBridge, Kinesis Streams, DynamoDB, and S3, while also contributing to architecture discussions, proposals, and stakeholder engagement with customer Enterprise Architects. Key Responsibilities 1) Hands-on Engineering (Primary Focus) Design, develop, and deploy TypeScript-based AWS services with a strong emphasis on serverless implementations Build event-driven integrations using Amazon EventBridge including routing, filtering, replay/error handling patterns. Implement stream processing / real-time ingestion using Amazon Kinesis Data Streams (consumer patterns, batching, checkpointing, scaling). Develop resilient AWS Lambda functions with proper observability, retries, idempotency, and performance tuning. Build data persistence and access patterns using Amazon DynamoDB (partition/sort key design, GSls, TTL, conditional writes). Use Amazon S3 for object storage patterns event triggers, lifecycle policies, encryption, pre-signed URLs where applicable). 2) API & Integration Development Implement APls using API Gateway and integrate with Lambda/DynamoDB. Build async workflows and messaging patterns (SQS/SNS as needed) alongside 5xentBridge and streams. 3) Quality, Testing, and DevOps Write comprehensive unit/integration tests (e.g., Jest; use LecalStack where appropriate). Work within CI/CD pipelines and DevOps practices to release frequently and safely. Ensure code quality, security posture, and automation standards are maintained. 4) Architecture, Proposals & Enterprise Architect Collaboration Contribute to architecture design and optimization of AWS solutions (scalability, resilience, security). Produce technical artefacts: solution approach, diagrams, assumptions, and estimates for proposals / SOW inputs. Collaborate with customer Enterprise Architects and senior stakeholders to align designs to enterprise standards and governance.
