AWS with Typescript

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 DataStreams (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.

2) 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.

3) 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.

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.

Required Skills & Experience (Must Have)

• Strong TypeScript (hands on) - building production services (Node.js runtime where applicable)
• AWS Lambda (hands on) - serverless development and production support.
• Amazon EventBridge (hands on) - event driven design and implementation.
• Amazon DynamoDB (hands on) - data modelling and performance aware access patterns.
• Amazon S3 (hands on) - storage integration patterns and secure access controls.
• Amazon Kinesis Data Streams (hands on) - stream ingestion/processing and consumer patterns.

Experience with supporting AWS services like API Gateway and CloudFormation (CDK).

• Strong understanding of cloud architecture and ability to work with enterprise architecture stakeholders.
• Strong knowledge of AWS security recommendations.

Preferred Qualifications

• AWS certifications: Developer Associate / Solutions Architect.
• Experience with microservices and security best practices in cloud environments.
