What you ll do

• Design & build RESTful APIs and microservices in C#/.NET and Node.js/TypeScript running on AWS Lambda behind API Gateway .

• Model, publish, and consume events ( EventBridge /SNS/SQS) to enable decoupled, event-driven architectures; implement idempotency, retries, DLQs, and observability.

• Work with storage : DynamoDB (NoSQL), RDS (SQL Server), S3 for object storage, and caching.

• Own the SDLC : write clean, testable code;maintain high standards ; ship via CI/CD.

• Instrument and operate services in production with CloudWatch, X-Ray, structured logging, and alarms; participate in a lightweight on-call rotation and post-incident reviews.

• Collaborate cross-functionally with product, QA, and DevOps to refine requirements, estimate work, and deliver incrementally.

• Continuously improve performance, reliability, and AWS cost efficiency ; profile hot paths and tune queries/indexes.

• Document APIs with OpenAPI /Swagger; write concise runbooks and ADRs for key decisions.

Required qualifications

• 3-5 years professional software engineering experience with a strong focus on C#/.NET

• Hands-on AWS experience building serverless backends with API Gateway, Lambda, EventBridge , and S3 .

• Practical Node.js/TypeScript experience (building utilities, Lambdas, or services).

• Solid understanding of HTTP, REST, JSON , async programming, and common integration patterns (webhooks, polling, callbacks).
