About our Mobile Engineering discipline
Our mobile engineers have a variety of different backgrounds
There are 40 iOS engineers at Monzo and were 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 wed love to talk to you.
Monzo works in small interdisciplinary teams
We have around 400 engineers out of roughly 4500 people in total - and we have big ambitions. There are many interesting challenges ahead and were happy for people to move between teams or to specialise whatever you prefer. As an engineer here youd be able to work directly with anyone across the company and we run regular knowledge-sharing sessions so youll learn heaps about everything from how banks work to effective communication.
We contribute to open source software as much as possible. Our blog is a good place to learn even more about what we do!
Your day-to-day
Were searching for product-focused iOS engineers to evolve our native mobile app. Youll take pride in building polished user experiences and youll balance the need for well-tested resilient code with moving fast and iterating.
Youll 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 youll 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 - youll 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 were encountering across the company and work together to improve our codebase and processes.
Youll report to an engineering manager who will meet with you every 1-2 weeks 1:1. Theyre dedicated to helping you grow and develop as an engineer.
Our iOS app
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 theyre 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.
Weve published some talks and blog posts about how we work:
- Working with backend services on iOS
- Pushing Protocols to their Limits
- Our mobile release process: An illustrated story
- What weve learnt building a design system in SwiftUI
