Data At Monzo
Their Data team’s mission is to Enable Monzo to Make Better Decisions, Faster

At the core of this mission sits their data platform. They’re great believers in powerful, real-time analytics and empowerment of the wider business. Every engineer at Monzo is responsible for the collection of relevant analytics events from their microservices. They optimize for simplicity and re-usability – all their data lives in one place and is made available via their data warehouse in Google BigQuery. 90% of day-to-day data-driven decisions are covered by self-serve analytics through Looker which gives data scientists the headspace to focus on more impactful business questions and analyses.

  • Own cost optimization of their Data Warehouse, spotting opportunities to refactor to reduce the cost of their batch jobs
  • Support the building of robust data models downstream of backend services (mostly in BigQuery SQL) that support internal management information as well as financial/regulatory reporting

  • Investigate and effectively work with colleagues from other disciplines to address and improve data quality

  • You strive for improvement in your work and that of others, proactively identifying issues and opportunities

  • They offer flexible working hours and trust you to work enough hours to do your job well, at times that suit you and your team.
  • Diversity and inclusion are a priority for them – if they want to solve problems for people around the world, their team has to represent their customers. So they need to attract the best talent and create an environment that supports and includes them. You can read more about diversity and inclusion on their blog.
  • If you prefer to work part-time, we’ll make this happen whenever they can – whether this is to help you meet other commitments or strike a great work-life balance.
  • The application process consists of a 30-min phone call with a recruiter, an initial call with someone from the team, followed by a practical written exercise, and 2-3 on-site interviews remotely via hangouts. They promise not to ask you any brain teasers or trick questions.
