- Make well-reasoned technical decisions and propose architectural improvements
- Ensure code quality through automated testing (unit and integration)
- Work with cloud infrastructure to support high-demand, distributed systems
- Collaborate on maintaining observability standards across services (structured logging, metrics,



and tracing)

Requirements
- 3+ years of full-stack development experience in production environments
- Proficiency in Java, with a proven track record of building end-to-end solutions
- Hands-on experience with AWS (EKS, Lambda, S3, CloudWatch)
- Strong experience with Node.js (NestJS preferred)
- Solid understanding of design patterns and strong judgment for structuring code and projects
- Proficiency designing and developing REST APIs and integrating with external APIs
- Advanced handling of asynchronous programming (Promises, event loop, error handling)

- Experience with both relational and non-relational databases
- Familiarity with event-driven architecture (SQS, RabbitMQ, or similar)
- Experience with Docker and a solid understanding of Kubernetes
