Overview

We’re on a mission to make money work for everyone. We’re waving goodbye to the complicated and confusing ways of traditional banking. With our hot coral cards and get-paid-early feature, combined with financial education on social media and our award winning customer service, we have a long history of creating magical moments for our customers. We’re not about selling products - we want to solve problems and change lives through Monzo.

About our Mobile Engineering discipline

Our mobile engineers have a variety of different backgrounds. There are ~40 iOS 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 400 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 iOS 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 12 million people already, and your work here will shape the way that people interact with their finances.

As an iOS Engineer at Monzo you\'ll work in a small, autonomous product squad alongside Android 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 iOS 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% Swift and our latest features are built in SwiftUI and using elements of The Composable Architecture. Historically we built using a Model- View-View-Model architecture (MVVM). We use Coordinators to ensure we can re-use flows wherever possible, and avoid tightly coupling one screen to another. We make heavy use of protocols and extensions throughout our app. Our networking stack is built upon Alamofire, using a generic interface to easily de-serialise objects of a certain type, and we mirror our backend micro-service architecture by building individual services to house our API logic. We log liberally to get alerted when they’re triggered in Sentry which we also use to monitor crashes. Our testing stack comprises of unit tests for business logic, stubbed API tests for pseudo-integration tests, snapshot tests for UI, and XCUITest for testing user input and sequencing.

We\'ve published some talks and blog posts about how we work:

• 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 Swift
• You’ve shipped and iterated on at least one app in the App 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 computer science principles

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.

Equal opportunities for everyone. Diversity and inclusion are a priority for us and we’re making sure we have lots of support for all of our people to grow at Monzo. This is integral to our mission of making money work for everyone. You can read more in our blog, 2024 Diversity and Inclusion Report and 2024 Gender Pay Gap Report.

We’re an equal opportunity employer. All applicants will be considered for employment without attention to age, ethnicity, religion, sex, sexual orientation, gender identity, family or parental status, national origin, or veteran, neurodiversity or disability status.

If you have a preferred name, please use it to apply. We don\'t need full or birth names at application stage.

Identity survey

Our goal at Monzo is to make money work for everyone. To do that, working at Monzo must work for everyone. We want to create an equitable, engaged and innovative workplace which gives people from all backgrounds the support they need to thrive and grow. This demographic survey will help us better understand the people who apply to work at Monzo. It\'ll help us see how different groups progress through our hiring process, and where we need to make improvements to be more inclusive. If you choose to fill it out, all of the information you give us is voluntary and anonymous to Monzo. It would be helpful if you still fill out the survey even if you choose "prefer not to say" for every question, as it\'s useful for us to understand & record this. We won\'t know if you choose to fill this survey in or not.
