Job description

Senior Full stack Backend leaning / Realtime Engineer (GCP

Node.js
Firebase)

About the role

Own the backend for a real-time ETA dairy / food delivery / collection , multi-tenant platform that streams live location data and delivers accurate ETAs at scale. You’ll design and build reliable, low-latency services, keep third-party API costs in check, and mentor team.

What you’ll do

Design and implement a multi-tenant backend (orgs → devices→ ordered stops).

Build real-time pipelines : ingest batched GPS updates, validate / rate-limit, publish to subscribers.

Compute ETA updates efficiently (mix of client-side progress + selective server recalculation).

Keep costs predictable for maps / routing APIs (batching, caching, cadence control, budgets / alerts).

Write tests, set up CI / CD, add logging / metrics, and keep the app stable.

Write secure access controls and data rules; prevent cross-tenant access.

Ship with strong observability (structured logs, dashboards, alerts) and automated tests.

Review PRs, set coding standards, and guide dev team.

Must-have skills

3+ years backend experience building real-time or event-driven systems in production.

Node.js + TypeScript with a framework like NestJS or Express.

Hands-on with Google Cloud : serverless functions, containerized services, pub / sub messaging, secret management, monitoring.

Firebase : Auth, Firestore / NoSQL, Realtime listeners, and security rules or equivalent experience with AWS / Supabase + websockets.

Practical integration with routing / ETA APIs (Google Maps) and strong cost-control habits.

Solid grasp of idempotency, backpressure, batching, retry policies, and data modeling.

Nice to have

Postgres / PostGIS or other SQL ; Redis

Experience sharding workloads, running load tests, and tuning cold-start / latency.

OSRM / Valhalla basics, Terraform, Sentry, BigQuery / Looker

Prior work on mobility, logistics, ride-hailing, delivery, or transit.
