Responsibilities

• Technical Leadership: Lead and mentor backend engineers, ensuring best practices in distributed system design, coding, testing, and DevOps.
• Architecture & Design: Own the end-to-end design of scalable, secure, and self-healing distributed systems and APIs.
• Cloud-Native Engineering: Build and operate containerized applications using Python, Docker, Kubernetes, Helm, with GitOps-driven workflows via ArgoCD.
• Distributed Communication: Architect systems with robust service-to-service communication using REST, gRPC, pub/sub, and event-driven messaging (Kafka, RabbitMQ), integrated with service meshes (Istio/Linkerd).
• Scalability & Reliability: Design horizontally scalable, resilient, and fault-tolerant systems with automated recovery, health probes, and graceful degradation.
• Traffic Management & Rate Limiting: Implement API gateways, rate limiting, quotas, and load balancing to protect services and enforce SLAs.
• CI/CD & DevOps: Define and optimize CI/CD pipelines (Jenkins, GitHub Actions, Argo Workflows) with safe deployment strategies (blue-green, canary, rollbacks).
• Database Design & Performance: Design and optimize relational and NoSQL databases, handle sharding/replication, and improve performance with caching (Redis, Memcached).
• Observability: Implement monitoring, logging, and tracing (Prometheus, Grafana, OpenTelemetry, ELK/EFK) for end-to-end visibility.
• Code Quality & Reviews: Set engineering standards, conduct code/design reviews, and ensure delivery of modular, maintainable, production-ready code.
• Collaboration: Work cross-functionally with product managers, DevOps/SRE, and architects to align business needs with technical solutions.
• Problem Solving: Diagnose and resolve performance bottlenecks, scaling issues, and complex failures in distributed systems.
• Innovation: Research emerging backend, cloud-native, and distributed systems technologies; drive adoption of impactful solutions.
