1–3 years of experience

Location: Versova, Mumbai

Full-time, in-office role.

Build product experiences that make discovering and experiencing live entertainment effortless.

Company: thumpN

thumpN is an AI-native discovery and ticketing platform that unifies discovery, ticketing, and on-ground tools for fans, artists, venues, and promoters.

WHY THIS ROLE EXISTS

thumpN is where the show begins.

At thumpN, we build products that make discovering and experiencing live entertainment effortless. From the moment a fan opens the app to the second they walk through the venue gates, every interaction is a product decision.

As we grow into new cities and categories, we need a frontend developer who can turn product and design ideas into fast, reliable, and delightful experiences across web and mobile.

This role is for someone who enjoys building things users actually interact with. Someone who cares about how a product feels, not just whether the code works. You will work closely with Product, Design, and Engineering to build experiences across event discovery, ticketing, payments, and on-ground experiences.

NON-NEGOTIABLES

How we know this is the right fit

You care about the product, not just the code.

You want to understand what you're building, who is using it, and why it matters. You don't see a ticket booking flow as just a collection of screens, you think about the experience of someone discovering an event and trying to get through the purchase journey.

You care about the details.

Good frontend development isn't just about making something work. You notice spacing, interactions, loading states, responsiveness, animations, errors, and the small details that make an experience feel polished.

You take ownership.

You don't stop when your component works on your machine. You think about edge cases, different devices, performance, testing, and what happens when real users interact with it.

You are comfortable learning.

You won't know everything when you join. That's expected. What matters is that you can investigate, ask good questions, read documentation, experiment, and figure things out. You should be excited to work with modern frontend technologies and AI-native products.

You have strong fundamentals.

Frameworks change. Good frontend engineers understand the fundamentals underneath them. You care about clean code, reusable components, responsive design, performance, accessibility, and maintainability.

You communicate clearly and work well with others.

Frontend development sits at the intersection of Product, Design, and Engineering. You ask when something isn't transparent, explain your thinking, and raise problems before they become bigger problems.

You want to build things people actually use.

The goal isn't to use the newest framework or write the most complicated code. The goal is to build experiences that help people discover great events, buy tickets effortlessly, and have a better experience around live entertainment.
