Android Engineer

London / UK Remote | £78,000 - £110,000 + Benefits | Technology - Engineering

We’re here to make money work for everyone and we're doing things differently. For too long, banking has been obtuse, complex and opaque.

We want to change that and build a bank with everyone, for everyone. Our amazing community suggests features, test the app and give us constant feedback so we can build something everyone loves.

We're focused on solving problems, rather than selling financial products. We want to make the world a better place and change people's lives through Monzo.

There are over 20 Android engineers at Monzo and we’re looking for one 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.

At Monzo, you'll get to work with industry standard tools and technologies - and help us define what great looks like for Android engineers.

Our app is almost 100% Kotlin, built using MVVM (Model View View Model) and Coordinators, and modularised by product feature.

We use RxJava, Retrofit and Moshi for API calls and Dagger for dependency injection. Room is our choice for persistence, and Repositories for interacting with them. We have built out our design system in Compose.

We use Git Hub Pull Requests to do code reviews, and write unit tests for our View Models, 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 through Firebase Test Lab and Circle CI.

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

This role is all about collaborating across disciplines to test hypotheses and make a difference to customers. 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, Data Scientists and Business Analysts.

Your mission will depend on the squad, but currently mobile engineers are working on the core personal banking experience, paid products, lending products, business banking and internal operations. We also have a small squad dedicated to enabling other mobile engineers to move faster.

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.

Every week we meet as a 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 2 weeks 1:1, their mission is to help you develop and grow as an engineer.

We're looking for Android engineers with strong product sensibilities. You'll care about the impact your work has on our customers, and optimise for impact rather than the number of lines of code you output.

• 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 of the principles of computer science

Our interview process involves three main stages:

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

You will have the chance to speak to our recruitment team at various points during your process but if you do have any specific questions or want to talk through reasonable adjustments ahead of or during application please us at any point on
