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
- 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, GSIs, TTL, conditional writes).
- Use Amazon S3 for object storage patterns (event triggers, lifecycle policies, encryption, pre-signed URLs where applicable).
- API & Integration Development
- Implement APIs using API Gateway and integrate with Lambda/DynamoDB.
- Build async workflows and messaging patterns (SQS/SNS as needed) alongside EventBridge and streams.
- Quality, Testing, and DevOps
- Write comprehensive unit/integration tests (e.g., Jest; use LocalStack 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.
- 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.
