Description
We're looking for a Machine Learning Engineer to join our London office as part of a Global DoorDash Engineering team. You'll work on the surfaces that make our new verticals happen: the homepage, vertical landing pages, and the notifications that bring people back.
What You'll Be Doing
- Build and improve ranking models for vertical landing pages, deciding what a user sees first when they land on a store page
- Design models that blend new-vertical content into a homepage built around restaurant ordering, without disrupting the core experience
- Build personalisation models that translate a user's existing behaviour into relevant recommendations for verticals they haven't tried yet
- Contribute to notification targeting , who gets notified, with what message, and when, to drive adoption of new verticals
What You'll Need to Thrive
- Minimum 3+ years of experience as an ML Engineer or Data Scientist, with a proven ability to write high-quality production code in Python
- Experience with end-to-end model productionisation
- A bias to simplicity, where you care most about achieving impact
- Background in personalisation, ranking, or recommender systems; exposure to causal inference or uplift modelling is a genuine plus but not expected
Why Join Us?
- Solve meaningful problems at real scale
- See your impact, fast
- Grow through challenge and ownership
- A culture built for builders
- Share in the success you help create
