⭐Our Writer team

Monzo’s coming to Spain, and we need a writer who can take our iconic brand voice and make it feel at home there. This isn't just about changing pounds into euros. It’s about deep product localisation and high-impact storytelling. We’d expect you to know what Spanish people are watching on a Tuesday night and doing on the weekend, and to weave that sort of hyper local knowledge into your writing. 

As our first dedicated Writer for the Spanish market, you’ll be the bridge between our global writing standards and local cultural nuances. You will work at the intersection of Product, Marketing, and Legal to ensure every word we publish – whether it’s a tiny button in the app or a giant billboard in Madrid – is clear, compliant, and unmistakably Monzo.

🔑You’ll play a key role by...

• Seeking out and owning high impact work: You’d be trusted as a leader on the ground, taking the initiative to suggest guidance and processes within the Spanish team (not just responding to briefs). 
• Finessing our product experience: You’ll write and edit in-app text for new features, customer onboarding, and notifications, ensuring a seamless and locally relevant user experience (UX).
• Adapting our tone: You’ll serve as the local ToV champion, expertly adapting our global guidelines to resonate with Spanish humor, dialect, and consumer expectations.
• Crafting campaigns: You’ll provide fast-turnaround support for the Spain Marketing Lead, crafting creative copy for social media, email, OOH, and SEO content.
• Navigating compliance: Working closely with our legal teams, you’ll ensure all communications are compliant with Spanish financial regulations and cultural sensitivities.
• Collaborating across teams: You’ll partner with Product Managers, Designers, and Engineers to ensure content is a driver of our launch timeline, not a bottleneck.
• Accelerating our growth in Spain: By building trust through clear, locally resonant copy, you’ll help us improve onboarding conversion, reduce customer friction, and safeguard the brand during its most critical launch phase.

🤩 We’d love to hear from you if…

• You are a seasoned pro: You have at least 5 years of experience in product and marketing writing.
• You understand complexity: You can take a complex fintech product and explain it simply. Experience in financial services or another regulated industry is a huge plus.
• You are a dual threat: You are equally comfortable writing a punchy marketing headline as you are mapping out a technical UX flow.
• You are autonomous: You’re used to managing multiple stakeholders and can ship high-quality work without constant oversight.
• You are an advocate for the user: You refuse to talk down to people and believe that "legalese" has no place in a modern bank.

🙌What’s in it for you

💰A salary range of €51,000 - €62,000 ➕ Incentive Awards tied to your performance.

📍This role will have a hybrid working model, based in our Barcelona/Madrid office 2 - 3 days a week, however, you will be expected to travel to Monzo’s head offices in Dublin and/or London from time to time.

⏰We offer flexible working hours and trust you to work enough hours to do your job well, and at times that suit you and your team. 

🏝 Annual Leave - 38 days including public holidays

📚€1,200 learning budget each year to use on books, training courses and conferences.

🏥Private healthcare scheme

💛Wellbeing benefits: financial education, women’s and men’s health support, mental health benefits, including coaching and counselling

🌈 The application journey has 4 key steps

• An introductory call with a Monzo Recruiter
• An initial call with the Hiring Manager
• A take home task
• A final round of role specific and behavioural interviews with relevant stakeholders

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

We have some guidelines on using Artificial Intelligence (AI) to ace an application and interview at Monzo. You can read them here.

We’ll only close this role once we have enough applications for the next stage. Please submit your application as soon as possible to make sure you don’t miss out. 

If you're successful in applying for this role, we'll work with you to find a start date. In some cases, there might be a delay in when you can be released from your current role so that we can make sure things continue to run smoothly. We’ll be sure to communicate this with you and keep you updated.

 ⭐Our Mobile Engineering team

There are ~40 Android 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.

🔑You’ll play a key role by...

We’re searching for product-focused Android 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 Android Engineer at Monzo you'll work in a small, autonomous product squad alongside iOS 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 Android 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 Android app

Our app is 100% Kotlin, built using MVVM (Model View ViewModel) and Coordinators, and modularised by product feature.

We use RxJava, Retrofit and Moshi for API calls and Dagger for dependency injection. We’re starting to use Coroutines for most new features. Room is our choice for persistence, and we use repositories for interacting with data. We’ve built out our design system with Compose. 

We use GitHub Pull Requests to do code reviews, and write unit tests for our ViewModels, Coordinators, and any other classes which contain logic. We write tests for all of our Compose screens and snapshot test them with Happo. We also use Espresso to test flows, which are executed via our continuous integration system.

We’ve previously written about building Monzo Chat on Android, which goes into detail on some of these elements.

🤩 We’d love to hear from you 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 Kotlin
• You’ve shipped and iterated on at least one app in the Play 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

We're on the look out for L30 Engineers at the moment, you can read more in our Engineering Progression Framework you will be interviewed across the whole framework, so if you're not sure what level you're aiming for chat to your recruiter!

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!

As a backend 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!
