Summary:

About the Role

You'll be a core individual contributor on the Fault Management team, building near-real-time streaming pipelines and intelligent fault-processing capabilities within our AIOps platform. You own module delivery end-to-end — from low-level design through production support — and work with platform architects and PMs to ship high-impact features.

Job Description – Senior Software Engineer

Responsibilities

Module Ownership

  • Own one or more fault-management modules end-to-end
  • Write LLD documents for every feature request and present for team review
  • Drive technical decisions within your module — velocity vs. reliability trade-offs

Near-Real-Time Pipelines

  • Build event-driven pipelines with Kafka Streams and Kafka Connect for fault ingestion, correlation, and enrichment
  • Implement Spark batch and micro-batch jobs for large-scale fault analytics
  • Meet SLA targets for latency, throughput, and fault tolerance

Backend Engineering

  • Build cloud-native microservices using Java and Spring Boot
  • Design idempotent consumers, DLQs, and back-pressure for exactly-once / at-least-once semantics

Agentic Development

  • Use LLM-assisted coding and AI pair-programming tools to accelerate delivery
  • Integrate ML-powered anomaly detection and RCA into fault workflows
  • Prototype new AI capabilities that improve automated fault resolution rates

Debugging & Incident Support

  • Diagnose issues across Kafka brokers, Streams topologies, Spark executors, and Spring Boot services
  • Primary escalation point for critical production incidents in your module
  • Write runbooks and post-mortems to prevent repeat incidents

Quality & Operational Excellence

  • Unit, integration, and contract tests; peer code reviews
  • Observability — metrics, tracing, structured logging; on-call rotation
  • Contribute to CI/CD and infra-as-code improvements

Required Skills

  • 6+ years of hands-on backend / data engineering experience
  • Production Kafka systems — topics, partitioning, consumer groups, offset management
  • Kafka Streams DSL and Processor API; stateful and stateless topologies
  • Kafka Connect — source and sink connectors, lifecycle management
  • Apache Spark — Structured Streaming, DataFrames, Spark SQL at scale
  • Java 11+ and Spring Boot 3.x — REST, security, reactive patterns
  • Deep debugging across multi-threaded, distributed JVM systems
  • LLD/HLD documentation; distributed systems principles (CAP theorem, eventual consistency)

Good to Have

  • AIOps or observability platform experience
  • Agentic development workflows or LLM-integrated toolchains
  • Telecom fault management standards (TM Forum, IETF YANG/NETCONF) or OSS/BSS domain knowledge
  • Kubernetes, service meshes, cloud-native deployments (AWS / Azure / GCP)
