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 ❤️

Hear from our UK team about what it's like working at Monzo ✨

 

📍New York, NY | Remote | 💰Backend Engineer III $161,500 - $218,500 + Benefits | Technology - Engineering | 

At Monzo, we’re building the future of digital banking - one that puts people first, not fees. We believe money should work for everyone, helping you grow, save, and spend in ways that actually fit your life.

We started in the UK and became one of the most loved digital banks, trusted by millions. Now, we’re bringing that same energy, innovation, and heart to the US, empowering people to take control of their finances with clarity, simplicity, and confidence.

Our US team is on a mission to make digital banking that grows your money, your way. Whether it’s cashback rewards that fit your real habits, high-yield savings with no hidden catches, or smart budgeting tools that simplify life, everything we build is designed to lift people up, not trip them up

But what truly sets Monzo apart isn’t just our product - it’s our people. We’re a team of builders, problem-solvers, and big thinkers united by a shared belief that finance can (and should) be fair, transparent, and empowering. We care deeply about the work we do and the impact it has on real people’s lives.

If you’re ready to make a difference and help build a bank that rewards people for being themselves, come join us. Let’s grow together.

About Us

Monzo Group is a leading financial technology company, with over 13 million customers in the UK, committed to providing modern banking solutions. In the last few years, we’ve built a banking app that our customers love – with extremely high daily engagement, an industry leading net promoter score, and award-winning customer support. We’ve raised over $1 billion from Capital G, Google’s growth fund, Ribbit Capital, TenCent, YCombinator, Stripe, Coatue, and others - most recently at a $5.9 billion valuation in 2024.

We’re just getting started in the US. We’re an agile full stack team operating like an early stage startup but with the financial, operational, and engineering platform muscle of a larger company. We’re focused on building an amazing US product, shipping and iterating quickly, and deepening our product market fit. We’re looking for highly driven, enterprising people to help us achieve our mission to make money work for everyone.

About our Engineering Team:

We are a team of 20 engineers working in a startup environment and on a mission to make digital banking work for everyone in the US. We have big ambitions for the future, and technology plays a big role in creating a bank our customers want. 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. There is scope for impact across a huge number of opportunities.

Your day-to-day   

This role is all about collaborating with your team to make a difference to your customers. 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! 

Together you’ll build the Monzo US application. You’ll work with squads across collectives (a word we use to describe self-governing business units of ~100 people). 

We do not ask for formal qualifications or degree requirements, our backend engineers have a variety of different backgrounds. As long as you enjoy learning new things, we’d love to talk to you.

How we work 💻:

Locations & Flexible Working : 

Our main tech hub is in New York, but our engineers live everywhere in the US. 

We value meeting in person but there’s no pressure to come into the office, even if you're nearby. We believe you'll do your best work if you are where you want to be. If you live outside of New York and we ask you to come into the office, Monzo will support you with the costs. ✨

Our offices are naturally social, especially Tuesdays, Wednesdays and Thursdays. Teams also schedule time together often for work and play – in or around the office, or online.

Set up a work schedule that delivers impact and fits your life.

At Monzo, we value connections, flexibility, and wellbeing. We keep our meetings during core hours to stay connected and believe in maintaining work/life balance. 

You’ll be empowered to manage your work in a way that suits you and your team, giving you the freedom for children drop-offs and pick-ups, walking your dog or adventurous cat, avoiding peak commuting times or gym slots, appointments, or supporting your family in an emergency. 🕒✨

  • Envoy Proxy for RPC
  • AWS for most of our production infrastructure and GCP for most of our data infrastructure

The Interview Process:

Our interview process involves three main stages: 

  1. Initial Call 
  2. Take home task or pair coding exercise

Our average process takes around 4 weeks but we will always work around your availability.

Voluntary Self-Identification of Disability

Form CC-305

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
