• Strong understanding of distributed-system concepts:

  • Scalability
  • High availability
  • Fault tolerance
  • Idempotency
  • Retry strategies
  • Eventual consistency
  • Service-to-service communication
  • Failure recovery
• Strong Docker and Kubernetes experience
• Experience writing clean, maintainable, well-tested production code
• Production application troubleshooting and support experience

Key Responsibilities

• Design, develop, test, and maintain scalable backend services using Node.js and TypeScript.
• Build large-scale distributed systems supporting enterprise platforms.
• Develop highly available, resilient, and fault-tolerant cloud-native services.
• Design APIs capable of handling significant transaction volumes.
• Make technical decisions involving performance, scalability, reliability, maintainability, and delivery speed.
• Build asynchronous and event-driven integrations.
• Deploy containerized applications using Docker, Kubernetes, and AKS.
• Develop CI/CD processes using GitHub Actions and Helm.
• Implement logging, metrics, tracing, and monitoring for production systems.
• Troubleshoot complex production issues across services and infrastructure.
• Develop automated unit, integration, and service-level tests.
• Participate in code and technical design reviews.
• Identify and address technical debt.
• Mentor engineers and promote strong engineering practices.
• Collaborate with architects, product managers, and engineering teams.
• Take operational ownership of applications after deployment.

Success Profile

The successful candidate will think beyond individual services and understand how backend components behave within a larger distributed ecosystem. They will build systems that are scalable, observable, reliable, resilient, and production-ready, while remaining actively hands-on with software engineering.
