Position: Backend Developer (Node.js)

Experience: 1.5 – 3 years

Location: Gurgaon

Employment Type: Full-Time-Onsite

About Us:

At SportsDunia, we build a live-scores and sports-content platform for football and cricket fans on Android, iOS and the web. Behind the app is a real-time data platform that ingests live feeds from sports data vendors, turns them into scores, commentary, line-ups, stats and standings in multiple languages, and delivers them to fans within seconds through live screens, streams and push notifications. Our mission is to be the go-to destination for sports fans across India and beyond.

Responsibilities:

Build and maintain server-side application logic in Node.js / Express for our mobile apps and website

Work on live data ingestion: consume vendor feeds (webhooks, MQTT, REST polling), normalise them and fan them out through Redis to the serving layer

Design REST APIs for match listings, match details, competitions, teams and players with a focus on low latency and correct caching

Work on real-time delivery: Server-Sent Events fan-out and Firebase push notifications

Model and query data in MongoDB (schemas, aggregation pipelines, indexes) and keep it consistent with what Redis serves live

Build and maintain scheduled jobs (cron seeders) that sync fixtures, competitions, teams, squads and rankings from vendors

Write clean, readable, testable code and review teammates' pull requests

Deploy to staging and production, read production logs, reproduce and debug live issues

Collaborate with mobile and front-end developers on API contracts

Work on security and data protection (secrets handling, access control)

Requirements:





1.5+ years of hands-on experience with Node.js in production; strong understanding of async/await, the event loop and error handling

Good working knowledge of Express (routing, middleware, validation, controller/service separation)

Working knowledge of MongoDB with Mongoose: schema design, aggregation pipelines ($lookup, $group), indexes

Working knowledge of Redis: key/TTL design, caching patterns, pub/sub

Understanding of REST API design: versioning, pagination, consistent error handling, mobile clients on slow networks

Modern JavaScript (ES2020+), Promises, working with JSON at volume

Thorough knowledge of Git and GitHub: feature branches, small focused PRs, rebasing and cherry-picking

Linux basics: SSH, reading logs, processes, setting variables, cron

Ability to reproduce an issue, measure before fixing, and explain what was found

Good to Have:

Real-time delivery: Server-Sent Events or WebSockets

Message streams / queues: Redis Streams, Kafka or similar

PM2, nginx, zero-downtime deployments; Docker basics

Cloud basics on Azure or AWS: VMs, load balancers, managed Redis

Firebase Cloud Messaging (topics, conditions, service accounts)

Experience integrating third-party sports data APIs (rate limits, webhooks vs polling, handling stale vendor data)

TypeScript; unit testing with Jest or similar

Python for scripting

Internationalisation (serving the same data in multiple languages)

Interest in football or cricket
