About our Mobile Engineering discipline
Our mobile engineers have a variety of different backgrounds
There are ~60 Android engineers at Monzo and weâre looking for more to join the team. We have several non-graduates; only some of us studied Computer Science; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, weâd love to talk to you.
Monzo works in small, interdisciplinary teams
We have around 650 engineers out of roughly 5,500 people in total - and we have big ambitions. There are many interesting challenges ahead, and we're happy for people to move between teams or to specialise, whatever you prefer. As an engineer here you'd be able to work directly with anyone across the company, and we run regular knowledge-sharing sessions so youâll learn heaps about everything from how banks work to effective communication.
Weâre searching for product-focused Android engineers to evolve our native mobile app. Youâll take pride in building polished user experiences, and youâll balance the need for well-tested resilient code with moving fast and iterating.
Youâll be working on a product that is a part of day to day life for more than 11 million people already, and your work here will shape the way that people interact with their finances.
As an Android Engineer at Monzo you'll work in a small, autonomous product squad alongside iOS Engineers, Backend Engineers, User Researchers, Product Designers, Product Managers, QA Testers, and Data Scientists.
You and your team will be responsible for an overall company goal, rather than building a specific feature - you'll have the opportunity to have impact on both what we build, and how we build it. Mobile engineers at Monzo work on everything from the personal banking product to customer support tools. We also have a small mobile platform squad dedicated to enabling other engineers to move faster.
Every week we meet as an Android discipline to discuss tools, techniques, problems we're encountering across the company and work together to improve our codebase and processes.
You'll report to an engineering manager who will meet with you every 1-2 weeks 1:1. Theyâre dedicated to helping you grow and develop as an engineer.
Our app is 100% Kotlin, built using MVVM (Model View ViewModel) and Coordinators, and modularised by product feature.
We use RxJava, Retrofit and Moshi for API calls and Dagger for dependency injection. Weâre starting to use Coroutines for most new features. Room is our choice for persistence, and we use repositories for interacting with data. Weâve built out our design system with Compose.
We use GitHub Pull Requests to do code reviews, and write unit tests for our ViewModels, Coordinators, and any other classes which contain logic. We write tests for all of our Compose screens and snapshot test them with Happo. We also use Espresso to test flows, which are executed via our continuous integration system.
Weâve previously written about building Monzo Chat on Android, which goes into detail on some of these elements.
