Backend Engineer

About ZillOut
ZillOut builds the operating layer behind how India goes out: nightlife, dining and live events, where real money moves every minute.
Clubs, cafés, sundowners and concerts run on one system: POS and ordering, entry and the digital cover, ticketing and reservations. Venues and organizers use it to run tighter operations, stop revenue leaks and understand their guests.
We're hiring a backend engineer to build the platform venues and organizers run on: entry, ticketing, reservations, ordering, and payments. Strong fundamentals matter more than years of experience, and frontend skills are a plus.
Role: Backend Engineer (Java / Spring Boot)
Experience: 0–2 years
Employment: Full-time
Location: Remote
What you'll work on
You'll ship backend features that venue staff, organizers and guests use the same week.
Build and maintain REST APIs in Java and Spring Boot for our merchant, partner and customer apps
Design PostgreSQL tables and keep queries fast on a busy Friday night
Work on money flows (bills, taxes, discounts, online payments and refunds), where every rupee has to add up
Build integrations: WhatsApp messaging, payment gateways, delivery platforms and thermal printers for KOTs and bills
Push live order updates over WebSockets and run background work through message queues
Debug production issues from logs and monitoring, then ship the fix
Agree on API contracts with frontend engineers, and make the small React change yourself when a feature needs both ends
What we're looking for
Experience is not a hard filter. A fresher with solid projects or internships is as welcome as someone with 1–2 years in a job.
Good Java fundamentals: OOP, collections, exceptions and the basics of threads
Has built a REST API with Spring Boot (an internship, college or personal project all count)
Comfortable with SQL: joins, indexes and transactions; PostgreSQL or MySQL
Understands HTTP: methods, status codes, JSON and how login sessions or tokens work
Uses Git every day: branches, pull requests and fixing merge conflicts
Reads unfamiliar code, debugs step by step and asks when stuck
Cares about getting it right: bills and payments are full of edge cases
Good to have
Frontend knowledge is the biggest plus. Engineers here often ship an API and the screen that uses it.
React: hooks, fetching data from APIs and forms; TypeScript or a component library like Chakra UI or MUI
JPA / Hibernate, Spring Security, JWT
Message queues (RabbitMQ or Kafka) and WebSockets
Docker, Linux basics, AWS (EC2, RDS, S3)
A side project that is live, or anything real people have used
An interest in restaurants, nightlife, or events

What you build goes live at real venues within a sprint
Small team: you own features end to end, from the table design to the screen
Learn backend, frontend, mobile and infra in one place
Work directly with the founders and see your work change how venues run
