About us:

At Monzo we’re aiming to build the control centre for peoples financial lives. We are always keen to hear from capable, creative engineers who want to help us accomplish that goal 🚀

We’re here to make money work for everyone and we're doing things differently. For too long, banking has been obtuse, complex and opaque.

We want to change that and build a bank with everyone, for everyone. Our amazing community suggests features, test the app and give us constant feedback so we can build something everyone loves.

We're focused on solving problems, rather than selling financial products. We want to make the world a better place and change people's lives through Monzo.

About our Engineering Teams:

We have around 200 engineers out of roughly 2,000 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 contribute to open source software as much as possible. Our blog is a good place to learn even more about what we do.

What you’ll be using:

We rely heavily on the following tools and technologies:

  • Go to write our application code (there’s an excellent interactive Go tutorial here)
  • Cassandra for most persistent data storage
  • Kafka for our asynchronous message queue
  • Envoy Proxy for RPC
  • Kubernetes and Docker to schedule and run our services
  • AWS for most of our infrastructure
  • React for internal web dashboards
  • We also have two physical datacenter sites with actual cables to connect to various third parties

Your day-to-day:

A Staff Engineer at Monzo is a technical (IC) leadership position. As a Staff Engineer in the Business Banking collective at Monzo, you’ll:

  • Work with the product leadership team of your collective to ensure we are making the right trade-offs across squads. You’ll use your keen sense of product market fit to do this.
  • Help your teams manage the trade-offs implied in shipping new product to market - balancing speed, polish and the need to learn what fits customers’ needs best.
  • Rally your team around a mission, objective or company priority, injecting urgency when needed or slowing down pace to make sure the right controls are in place.
  • Understand several work-streams across your group keeping enough context to regularly provide technical advice to other engineers.
  • Use your expert knowledge and experience to lead architectural discussions for the most complex systems in the collective. You’ll do this in order to arrive at solutions that are robust and optimal given the context.
  • Keep a high bar for technical excellence in the collective, through your own work, highlighting the work of others and calling out when things haven’t quite met the bar.
  • Foster a culture of quality within the collective. Proactively championing measures to test work, and get buy-in from stakeholders when this is not appreciated.
  • Pro-actively mentor, sponsor and up-level engineers.

Our vision in Business banking is to become the “Financial control centre” for SMEs

We are aiming to do this by providing the features, funding and services that businesses need. We want to integrate seamlessly with their existing tools to make them more powerful, and automate painful manual processes for SMEs.

Building on the Monzo experience we want to adopt and enhance our existing features and provide new features that are specific to businesses. For example, building on top of Pots we provide businesses with Tax pots that allow them to automatically put money aside on every incoming payment to be used later in the year as they file their taxes. We also build new Business specific features like the Invoices that allow businesses to create, send and manage their Invoices directly via their account.

Our main challenges evolve around:

  • building features that allow Business to manage their account
  • enable multiple users to have access to and manage the same account
  • integrating with 3rd parties to connect to the tools that Businesses use, whilst maintaining customer data accurate and easily accessible
  • managing and maintaining accurate data for Businesses as they are more complex structures

Our teams have a wide remit working vertically across all the layers of the application from the apps to the backend systems, and also horizontally across operations and internal tooling to make sure we provide the best customer experience across the board.

You should apply if:

  • you have a track record of technical excellence, delivering resilient systems, behind user facing products.
  • you have technically led teams to solve complex product challenges, enabling them to manage trade-offs in order to deliver products that solve customer needs at scale.
  • you have strong experience working on the backend of a technology product.
  • you want to be involved in building a product that you (and the people you know) use every day.
  • you have a product mindset: you care about customer outcomes and you want to make data-informed decisions.
  • you’re comfortable working in a team that deals with ambiguity and have experience helping your team and partner team resolve that ambiguity.
  • you have experience building and developing distributed systems and writing resilient software
  • you have significant experience working with more than one programming language, at least one of which is strongly typed (Go, Java, C, Scala etc.)
  • you have experience coaching and growing senior and junior Engineers.
  • you think you’d enjoy the kind of work we’re doing.
