This is an opportunity to join a high-traffic consumer product used by millions of people every month, where mobile is a core part of the experience rather than an afterthought.

You’ll be joining an established engineering function with 25+ engineers in the UK (50+ globally), working on iOS and Android apps that see millions of active users and real‑world impact every single day.

The mission is simple but ambitious: build a mobile app that users genuinely trust, return to daily, and rely on to make better purchasing decisions. You’ll play a key role in shaping how that experience looks, feels and evolves.

This role suits someone who cares deeply about product quality, enjoys ownership, and wants to work on a mature app where engineering standards matter.
