Meet Antoine, your hiring manager.


Antoine thrives on applying quantitative methods to real-world problems, and brings years of experience as a data science and machine learning leader: from quantitative trading algorithms to unmanned flight control systems, to language models on unstructured text.

Originally an applied mathematician, Antoine has published several academic papers related to imaging, finance, genetics and machine learning. An ex startup founder, he loves building AI solutions from the business perspective down to the engineering elements, rather than the other way around.



Instead of promising the moon (things you’ll work on per the JD) and delivering a regression (the linear one you’ll do on-the-job), here is a sampling of the kind of projects already developed by the team you’d be joining!

  • Cross-platform gamified app based on social engagement.
  • Product recommendation engine leveraging purchase data and web events.
  • Ingredients similarity-based graph database and guest experience mapping.
  • Embedding-based clustering of beauty-specific color swatches.



The Senior Data Scientist will be an integral part of the team focused on personalization – everything guest-centric. You relish the challenge of a blank page problem, and building out guest-focused B2B solutions.


Comfortable with varied fields spanning weakly supervised learning, classification, unsupervised learning and more, you’re even more comfortable with picking up new approaches as needed. You write modular and extensible code and rapidly experiment with new ideas.


You will report to our Lead Data Scientist, and work closely with other (Senior) Data Scientists across the team. Most of your work will be in an individual contributor role, with plenty of opportunities to flex those communication skills through internal presentations and cross-functional share-outs. Opportunities for mentorship and management experience could arise quickly if you’re interested in that facet of the job as well!


This is a great opportunity to come in at the ground level and make your mark in a startup environment, while delivering products that impact millions of guests every day.
