Senior iOS Engineer

About Monzo

We’re on a mission to make money work for everyone. We’re waving goodbye to the complicated and confusing ways of traditional banking. After starting as a prepaid card, our product offering has grown a lot in the last 10 years in the UK. As well as personal and business bank accounts, we offer joint accounts, accounts for 16-17 year olds, a free kids account and credit cards in the UK, with more exciting things to come beyond. Our UK customers can also save, invest and combine their pensions with us.

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 the team

Our mobile engineers have a variety of different backgrounds. There are ~60 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 650 engineers out of roughly 5,500 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.

We contribute to open source software as much as possible.

What you’ll do

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 11 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.

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.

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.

What we’re looking for

• 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

What’s in it for you

• Base salary for this role is depending on experience + Incentive Awards tied to your performance + benefits
• 📍Barcelona, ESP
• We offer flexible working hours and trust you to work enough hours to do your job well, at times that suit you and your team
• Learning budget of €1,200 a year for books, training courses and conferences

Interview process

The application journey has 3 key steps:

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

This process should take around 2-3 weeks - your schedule is really important to us, so we promise to be as flexible as possible!
