Job Description

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 ❤️


 

Barcelona, Spain | Base salary for this role is depending on experience + Incentive Awards tied to your performance  + benefits 
Hybrid model: 3 days a week in the office

⭐ Our Engineering Teams:

We have over 400 engineers across Monzo who design and build our in-house banking platform. We have big ambitions for the future, and technology plays a big role in creating a bank our customers want, so engineers at Monzo collaborate across disciplines to solve interesting challenges throughout the company.

These range from the products our customers use everyday to underlying infrastructure, security, payments and finance, customer operations, financial crime, and data, to name just a few areas. As a bank, there is scope for impact across a huge number of opportunities.

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   

This role is all about collaborating with your team to make a difference to your customers. As a web engineer you’ll work in a squad alongside other disciplines like product managers, marketers, user researchers, designers, mobile engineers, web engineers, data analysts, business analysts, writers and more! 

Together you’ll build and support a particular part of Monzo. Our squads belong to our wider collectives (a word we use to describe self-governing business units of ~100 people). They are; Core Banking, Business Banking, Wealth, Borrowing, Growth, Payments, Platform, Fincrime, Security & Expansion.

You’ll play a key role by...

  • Working closely with designers to iterate and improve on the user experience (UX) of the web banking platform, building accessible and intuitive interfaces.
  • Actively contributing to every stage in the product development lifecycle within your team, and owning the development of new features from start to finish.
  • Working closely with our backend engineers to design APIs to support new frontend features.
  • Collaborating with other web engineers to add brand-new features to the Payments Acquiring web platform.

Our software engineers have a variety of different backgrounds

We have plenty of non-graduates: only some of us studied Computer Science; some of us have worked in huge companies; some have only ever worked in startups and others are former consultants. As long as you enjoy learning new things, we’d love to talk to you.

We’d love to hear from you if…
