iOS Engineer Cardiff, London or Remote (UK)

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 Practice

Our mobile engineers have a variety of different backgrounds.

There are ~30 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 project-based sprints in small, interdisciplinary teams.

We have 350+ engineers out of roughly 4,000 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-awareiOS engineerswith a passion for great UI and UX to join our team. You understand the need for tested, resilient code balanced against the need to move fast and iterate.

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.

This role is all about collaborating across disciplines to test hypotheses and make a difference to customers. 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, 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 bothwhatwe build, andhowwe build it.

Every week we meet as a discipline to discuss tools, techniques, and 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.

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

Our app is 100% Swift, built using a Model, View, View-Model architecture (MVVM). We use Coordinators to ensure we can re-use screens 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 persist objects using Realm when we need to.

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.

• You 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 are 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 the principles of computer science.

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 reach out to us at any point on .
