We’re ASOS, the online retailer for fashion lovers all around the world. We exist to give our customers the confidence to be whoever they want to be, and that goes for our people too. At ASOS, you’re free to be your true self without judgement, and channel your creativity into a platform used by millions. We are proud members of Inclusive Companies, Disability Confident Committed and have signed the Business in the Community Race at Work Charter. We placed 8th in the Inclusive Top 50 Companies Employer list. Everyone needs some help showing up as their best self. Let our Talent team know if you need any adjustments throughout the process in whatever way works best for you.

We are looking for a Senior Data Scientist, with expertise in causal inference and statistics, to join our cross-functional Marketing Effectiveness team. Our Marketing Effectiveness team plays a key role helping ASOS provide the best shopping experience to millions of customers, using techniques such as incrementality testing and media mix modelling to understand, measure and optimise marketing spend. The role offers broad exposure to ASOS, requiring close collaboration with retail, marketing and technology divisions.

Details:

• 
  
• Driving the technical development and improvements of our geo-experimentation product used to model incremental uplift of ASOS’ digital spend, and our media mix modelling capability that supports long‑term media planning.
  
• You will be keeping up to date with relevant state‑of‑the‑art research, taking part in reading groups alongside other scientists, with the opportunity to publish novel prototypes for the business at top conferences.
  
• You will be continually developing and improving our code and technology, taking an active role in the conception of brand‑new features for our millions of global customers.
  
• You will be mentoring and coaching junior members of the team, supporting their technical progress.
  

We believe being together in person helps us move faster, connect more deeply, and achieve more as a team. That’s why our approach to working together includes spending at least 2 days a week in the office. It’s a rhythm that speeds up decision‑making, helps ASOSers learn from each other more quickly, and builds the kind of culture where people can grow, create, and succeed.
