• 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.
