About the job

Senior Software Engineer (SDE-2 / SDE-3) — 30 Sundays

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 for SDE2, 4-7 years for SDE3 of backend experience shipping production

systems

● Deep expertise in Node.js — built and scaled high-traffic services

● Strong SQL + NoSQL fundamentals

● B.Tech from top IITs, NITs, or BITS Pilani

● Prior experience at a consumer tech / consumer-facing product company

● Comfortable using AI coding tools as a force multiplier
