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. 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.

Locations & flexible working:

Our main tech hub is in London, but our data teams are based all over the UK. We love meeting in person, but there's no pressure to come into the office, even if you're nearby. You'll do your best work where you feel most comfortable. We value flexibility, connection, and wellbeing. You'll have the freedom to work in a way that fits your life, whether that's school drop-offs, avoiding rush hour, or making time for what matters most.

Your responsibilities as a Lead Analytics Engineer will include:

  • Serving as a data architect for Monzo's Operations data, contributing to the design and scalability of data models that measure the performance of our Operations product suite.
  • Develop robust data models downstream of backend services, primarily in BigQuery, to support internal reporting, machine learning, large language models, as well as financial and regulatory use cases.
  • Scope, build and lead the re-architecture of entire domains across Operations, including data about our workforce and about demands of our customers.
  • Be a key voice in shaping and maintaining best practices for our Data Warehouse, including source data payload design, logical data modelling, implementation, metadata, and testing standards.
  • Collaboratively set standards and work with data across Monzo, fostering knowledge sharing and continuously improving data practices.
  • Contribute to prioritising data governance issues, ensuring a comprehensive approach to data integrity and compliance.
  • Be a key technical leader who champions central platform initiatives that aim to elevate the data standards across Operations and beyond.
  • Own and support the pipelines we contribute to; on call support out of hours may be expected from time to time.

You should apply if:

  • You have a strong passion for data modelling, ETL projects, and Big Data.
  • You enjoy working with data streams from various services, such as financial, transactional, and operational systems.
  • SQL and data modelling are second nature to you, and you are comfortable with general Data Warehousing concepts.
  • You are committed to continuous improvement, proactively identifying opportunities and addressing challenges in your work and the work of others.
  • You have experience building robust and reliable data sets that require a high level of control.
  • You enjoy working with cross functional fast moving teams and are passionate about serving our customers.
  • You can think strategically about credit products and how our underlying data models will unlock more insights for our team and more value for our customers.
  • You are excited about enabling other data scientists, analytics engineers and credit analysts by sharing your expertise on data architecture.
  • You have the ability to shape big, ambiguous data domains and get the required buy in from key leaders across the business.
  • You can shape and manage the technical roadmap of an entire domain and execute against the project plan's deliverables.
  • You lead through the contributions of others by effectively leveraging the multiplier effect to create exponential value across Operations and Analytics Engineering.
  • You excel in cross functional stakeholder communication (back end engineers, product managers, and credit analysts), while also effectively engaging with senior technical leaders.

What's in it for you:

  • We can help you relocate to the UK and sponsor visas.
  • This role can be based in our London office, but we're open to distributed working within the UK (with ad hoc meetings in London).
  • We offer flexible working hours and trust you to work enough hours to do your job well, at times that suit you and your team.
  • Learning budget of £1,000 a year for books, training courses and conferences.
  • And much more - see our full list of benefits here.
