Job description

Our mobile engineers have a variety of different backgrounds

There are ~40 Android engineers at Monzo and we’re 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, we’d love to talk to you.

Monzo works in small, interdisciplinary teams

We have around 300 engineers out of roughly 4,500 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 you’ll learn heaps about everything from how banks work to effective communication.

We’re searching for product-focused Android engineers to evolve our native mobile app. You’ll take pride in building polished user experiences, and you’ll balance the need for well-tested resilient code with moving fast and iterating.

You’ll 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. They’re 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. We’re starting to use Coroutines for most new features. Room is our choice for persistence, and we use repositories for interacting with data. We’ve 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.

We’ve previously written about building Monzo Chat on Android, which goes into detail on some of these elements.

You should apply if

• You care about the impact your work has on our customers, and optimise for outcomes rather than the number of lines of code you output
• You’re excited about and have experience in programming in Kotlin
• You’ve shipped and iterated on at least one app in the Play Store
• You have a product mindset: you care about customer outcomes and you want to make data-informed decisions
• You love turning excellent design into beautiful products
• You’re comfortable working in a team that deals with ambiguity
• You have an understanding computer science principles

The Interview Process

Our interview process involves three main stages:

• Initial Call
• Take home task or pair coding exercise
• Final interview including a system design and a behavioural interview

Our average process takes around 2-3 weeks but we will always work around your availability.

You can also email [e-mail] if you have any specific questions or want to talk through reasonable adjustments ahead of or during application.
