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).

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.

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.
