Staff Engineer – Data Platform

📍London / UK Remote | 💰 £130,000 – £180,000 + Benefits | Technology – Engineering

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 300 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/What you’ll be working on:

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
  • Staff Engineer Responsibilities

A staff engineer at Monzo is a technical (IC) leadership position. As a Staff Engineer in the Data Platform 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 their collective. Proactively championing measures to test work, and gets buy-in from stakeholders when this is not appreciated.
  • Pro-actively mentor, sponsor and up-level engineers

About Data Platform

Our Data team’s mission is to Enable Monzo to Make Better Decisions, Faster and at the core of this mission sits our data platform. We have a strong culture of data-driven decision making across the whole company. And we’re great believers in powerful, real-time analytics and empowerment of the wider business.

This team owns the data platform infrastructure, data tooling, Airflow instrumentation, Data Access and Data retention tooling across Monzo.

  • Infrastructure and pipeline reliability and scalability
  • Improving our change management tooling across the data discipline
  • Building on our data privacy and data retention foundations
  • Designing and validating compute primitives to support better and more flexible incremental processing
  • Platform optimisation for better cost efficiency and scalability
  • Data is one of Monzo’s top priorities so there are lots of opportunities to have a huge impact on how we use Data at the company. You’ll have the opportunity to partner with other EMs and engineers across the Data discipline and beyond to shape and deliver our data strategy, and explore seeding new teams where there’s the opportunity.

You’ll provide a crucial bridging role in applying engineering best practices to the Data domain.

It’s a unique opportunity to have an outsized impact.
