Enable Monzo to Make Better Decisions, Faster

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. All our data lives in one place and is super easy to use. 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.

As a Staff Data Scientist, you’ll lead efforts on strategically important, business-critical problems. You’ll apply judgement in areas of organisational or technical complexity, steward initiatives end-to-end, and focus your hands-on contribution where it can create the greatest impact.

You’ll play a key role by...
  • Shape and lead the data strategy for a large domain or collective
  • Identify, frame and lead strategically important problems where the path is ambiguous
  • Partner with senior leaders across product, engineering, ML, design, research, risk and operations
  • Establish measurement strategies and metric maps
  • Set and evolve best practices for experimentation, causal inference, forecasting, optimisation and decision science
  • Remain hands-on where your expertise is most valuable
  • Steward critical data products and initiatives end-to-end
  • Coach and mentor data scientists and analytics engineers
We’d love to hear from you if…
  • You have an exceptional track record of leading complex, business-critical Data Science work
  • You have shaped strategy across a large product or business domain
  • You bring deep expertise across several Data Science disciplines
  • You repeatedly create clarity across organisational boundaries
  • You communicate complex ideas, assumptions and risks with clarity
  • You remain a highly credible hands-on practitioner with SQL and Python
What’s in it for you
  • £124,400 - £165,000 + Incentive Awards tied to your performance + Benefits
  • We can help you relocate to the UK or Spain
  • We can sponsor visas
  • This role can be based in our London or Barcelona offices, but we’re also open to distributed working within the UK
  • We offer flexible working hours
  • Learning budget of £1,000 a year for books, training courses and conferences
  • If you prefer to work part-time, we’ll make this happen whenever we can
