Job description

30 Sundays is a modern holiday company helping Indians plan and book international trips. Founded by IIT–IIM and ex-Apple leaders, with a core team from Flipkart, Spinny, and OYO. Backed by Info Edge and Eximius.

The team:

We’re building a deliberately small, agentic‑first engineering team. Every engineer ships meaningful surface area, leverages AI tooling aggressively, and owns systems end‑to‑end. No layers between you and the outcome.

What you’ll build:

• Consumer App — a best‑in‑class travel discovery and booking experience: feeds, search, recommendations, and personalization for Indian travellers.
• Internal tools — Sales and Ops productivity platforms that let a lean business operate at scale: agent workbenches, supplier tools, ops dashboards.

Responsibilities:

Design and ship backend services and REST APIs. Own data modelling, schema, and query optimization across SQL and NoSQL. Debug production, integrate third‑party APIs, and define architecture patterns the team builds on.

What we’re looking for:

• 2–4 years of backend experience shipping production systems
• Deep expertise in Node.js — built and scaled high‑traffic services
• B.Tech from top IITs, NITs, DTU, NSIT, BITS Pilani or equivalent
• Prior experience at a consumer tech / consumer-facing product company
• Comfortable using AI coding tools as a force multiplier
