Senior Frontend Engineer

About Timeleft

Timeleft is a social app that brings strangers together for IRL events. Every week, we match people into groups of 6 across 200+ cities in 52 countries. We're a fast-growing B2C subscription business.

What you build will be used by 150,000+ people every week — discovering their match, chatting with their group, finding the restaurant, and sharing how their evening went. Features ship weekly, your code goes live fast, and you see the impact immediately.

Role Overview

We are looking for a Senior Mobile Engineer to join the App team and help build the next generation of the Timeleft experience. Our product is a React Native + Expo application running on iOS, Android, and Web, backed by a NestJS API.

You will work alongside experienced mobile engineers and collaborate closely with product, design, QA, and backend teams. You'll own features end-to-end — from technical scoping through implementation, testing, and release — and contribute to the architecture and quality of a codebase serving users across 40+ cities worldwide.

This is a high-impact role where your code ships weekly and directly affects how people connect. We are an AI-first engineering team that uses AI tools to accelerate delivery while maintaining strong engineering standards. You'll be expected to use AI coding tools as part of your daily workflow to work effectively with modern development tooling and workflows.
