Senior iOS Engineer

About Monzo

We’re a bank on a mission to make money work for everyone. By focusing on solving real problems rather than selling financial products, treating people fairly and being totally transparent, we believe we can make banking better.

Monzo started in 2015 with big plans and a little office in Shoreditch, London. Now we’re a fully-licensed bank with millions of customers in the UK, and well over a thousand employees around the world.

Position

Engineering at Monzo

There are 13 iOS at Monzo, and we're looking to grow the discipline to 25 people over the course of the year.

We have several non-graduates; only some of us studied Computer Science; one of the team has a degree in Marketing; 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.

We encourage an open and transparent working environment

You can get involved in any aspect of the business you are interested in and, following Stripe’s example, all emails in the company are visible in an email archive. We’ve also made our product roadmap public and give sneak peeks of features in our community forum. Our blog is a good place to learn even more about what we do!

Our iOS app

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 KIF 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
• The Release Mindset (how we release our apps)

What you'll be doing

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 Business Analysts.

Your mission will depend on the squad, but currently mobile engineers are working on customer growth, revenue, 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 both what we build, and how we build it.

Every week we meet as a 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, and we have specific managers who have a background in mobile engineering. Your manager will meet with you every 2 weeks 1:1, and their mission is to help you develop and grow as an engineer.

Your qualification

• You are excited about programming in Swift
• You’ve shipped and iterated on at least one app in the App Store
• You love turning excellent design into beautiful products
• You enjoy developing apps that delight users
• You’re comfortable working in a team that deals with ambiguity every day
• Have an understanding of the principles of computer science

Will be a plus

• Familiarity with Android engineering, or other programming languages
• Contributing to open source projects

Additional details

Our main office is near Moorgate in London, though you have the opportunity to work remotely as long as you can spend around 20% of your time in London. We can help you relocate to London and we can sponsor visas!
