Senior Backend Engineer (Realtime + Scale + Production Ownership)Realtime Systems (Tracking + ETA)Company DescriptionJoining bonus:Harley-Davidson X440 / Royal EnfieldAbout the roleOwn the end to end backend and production for a real-time ETA (dairy/food collection-towarehouse), multi-tenant platform that streams live location data and delivers accurate ETAsat scale. Your responsibility is to design, ship, and operate the backend so real-time updates +ETA remain reliable, low-latency, secure, and cost-controlled at large scale, and mentor team.What you'll do1) Architecture + Delivery PlanDesign the full scalable system blueprint (data model, APIs, realtime flow, auth, cost-control) and define a clear staging→production rollout with reliability guardrails so the team can implement confidently.2) Realtime Location + Fan-outBuild the collector GPS ingestion pipeline (validated + throttled) and stream updates only to authorized subscribers, ensuring reconnect/late-join/resume works smoothly under peak load.3) ETA Engine + Cost ControlDeliver stable, accurate ETA without excessive Maps calls by using caching/route snapshots/periodic recalibration (and client-assist where useful), with graceful fallback behavior during traffic/mapsfailures.4) Alerts + NotificationsImplement 10-min and 5-min arrival alerts with anti-spam debouncing, delivered through in-app events and push notifications (FCM/APNS) reliably at scale.5) Multi-tenant SecurityEnforce strict tenant isolation across auth/API/DB, secure collector onboarding/auth (token/QR with rotation), and prevent abuse via rate limiting and protections against replay/spoofing/tenant hopping.6) Production OwnershipOwn shipping quality: CI/CD, environment config, monitoring/alerts/dashboards, reliability patterns (idempotency/retries/rollback), and load testing + performance tuning for peak windows.7) Mentor teamProvide strong backend contracts, review and guide implementations, and keep delivery fast but maintainable by enforcing clean patterns and production-grade standards.Tech stack (AWS or GCP — both accepted)We are flexible on cloud provider.
