Why this role

Help build resilient back-end services that power real-time communications analytics and automation at scale.

You’ll design APIs, process streaming data, and integrate with voice/telephony and cloud services to deliver low-latency, high-reliability experiences.

What you’ll do

  • Design and ship backend APIs (Django/DRF), background/async jobs (Celery/RQ), and secure integrations with external services.
  • Build and optimize real-time data pipelines for call/quality metrics; own observability, tracing, and SLOs (p95/p99).
  • Troubleshoot SIP/VoIP issues using packet captures and logs; automate analysis where possible.
  • Containerize workloads with Docker, contribute to CI/CD, and collaborate on cloud deployment (Azure/AWS).
  • Apply distributed-systems patterns (idempotency, retries, backoff, circuit breakers) for scale and fault tolerance.
  • Model data in PostgreSQL and MongoDB; tune indexes/queries; maintain migration discipline.
  • (Good-to-have) Prototype AI/ML features for analytics, anomaly detection, and conversational agents.

What you’ll bring (must-have)

  • Python & Django: RESTful APIs, authentication/authorization, background tasks, testing, and performance tuning.
  • Networking fundamentals: TCP/IP, DNS, TLS, HTTP/2; practical debugging with Wireshark; familiarity with NetFlow/SNMP.
  • Telephony domain: SIP signaling, RTP/RTCP, call flows, PSTN/VoIP basics; exposure to SBCs.
  • Cloud & DevOps: Working knowledge of Azure/AWS, Docker; Kubernetes exposure is a plus; comfort with CI/CD and secrets management.
  • Distributed systems: Microservices, event-driven design (queues/streams), horizontal scaling, resilience patterns.
  • Databases: Hands-on with PostgreSQL and MongoDB (schema design, indexing, migrations, backups/restore).
  • Mindset: Ownership, bias to automate, clear writing, and a product quality bar that values reliability and latency.

Nice to have

  • Kubernetes (Helm), IaC (Terraform/Bicep), metrics/log stacks (Prometheus/Grafana/ELK), OpenTelemetry.
  • Experience with Microsoft Graph/365 ecosystems, webhooks, or real-time comms SDKs.
  • Practical AI/ML: time-series anomaly detection, clustering, or LLM-powered workflows.

90-Day success profile

  • 30 days: Ship a well-tested Django service with one external integration; add dashboards/alerts for core SLOs.
  • 60 days: Deliver an automated SIP call-flow parser or PCAP → insights tool; reduce a p99 latency or error budget hot spot.
  • 90 days: Lead a small initiative end-to-end (design → deploy → postmortem), document runbooks, and mentor a junior dev.

What we offer

  • Impact on critical, high-scale real-time systems.
  • Autonomy, fast feedback loops, and a builder culture.
  • Competitive compensation; remote-first with flexible hours aligned to IST.
