📍London/ UK remote | 💰 Engineer III £78,000 - £110,000 base salary per year ➕ share options | Benefits | Technology 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 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 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 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 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: Working with backend services on iOS Pushing Protocols to their Limits Our mobile release process: An illustrated story What we've learnt building a design system in SwiftUI 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 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 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 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 tech-hiring@monzo.com Please also use that email to let us know if there's anything we can do to make your application process easier for you, because of disability, neurodiversity or an
