- Implement security best practices including authentication, authorization, rate limiting, and input validation.
- Write comprehensive unit, integration, and end-to-end tests to ensure system correctness and reliability.
- Deploy, monitor, and maintain services in staging and production environments using CI/CD pipelines and observability tools.
- Collaborate effectively with cross-functional teams including frontend, DevOps, and product to accelerate the delivery of high-quality features.

- Experience with backend frameworks like Express/NestJS, Django/FastAPI, Spring Boot, or Gin/Fiber.
- Strong understanding of relational (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis) databases.
- Expertise in API design principles, including REST, GraphQL, pagination, versioning, and error handling.
- Familiarity with authentication protocols such as JWT and OAuth2, and session handling.
- Solid grasp of security principles, including protection against XSS, CSRF, SQL Injection, and secure password handling.
- Experience with Docker for containerization and deploying microservices.
- Understanding of caching mechanisms (Redis, CDN), background processing (e.g., BullMQ, Celery), and job queues.
- Working knowledge of Git workflows and code review best practices.
- Comfort with CI/CD pipelines and automated deployments using tools like GitHub Actions, Jenkins, or GitLab CI.
Nice to Have
- Experience with cloud platforms such as AWS (EC2, S3, RDS, Lambda), GCP, or Azure.
- Familiarity with Kubernetes or other container orchestration solutions for service scaling.
- Hands-on experience with monitoring and logging tools like Prometheus, Grafana, ELK stack, Datadog, or Sentry.
- Experience building event-driven architectures using Kafka, RabbitMQ, or other pub-sub systems.
- Exposure to real-time systems utilizing WebSockets, Socket.io, or Server-Sent Events.
- Prior work on serverless architectures using AWS Lambda or GCP Functions.
- Basic experience with ETL pipelines or streaming data.
