(Senior) Applied Scientist, Recommendations

Own applied ML problems end to end: frame the problem, analyze data, develop models, define offline evaluation, run experiments and monitor production performance.

Develop methods that balance relevance with product and customer needs, such as diversity, availability, business constraints and changing user intent.

Collaborate closely with Software Engineers, ML Engineers, Product Managers and Analysts to turn scientific insights into reliable customer-facing products.

Evaluate and apply state-of-the-art ML methods where they meaningfully improve recommendation quality, robustness or efficiency.

Contribute to a high bar for applied-science practice through technical reviews, knowledge sharing and thoughtful experimentation.

Our humble expectations

You have substantial hands-on experience applying machine learning to real-world problems and a track record of bringing models from development into production; a PhD with relevant applied research experience is equally welcome.

You have experience with recommendation systems, ranking, retrieval, personalisation, or closely related ML problems.

You can independently turn an ambiguous customer or product problem into a well-scoped ML approach, make sound trade-offs and drive it to a measurable outcome.

You are proficient in Python and experienced with modern ML frameworks and large-scale data processing.

You understand how to evaluate ML systems rigorously, including offline metrics, experiment design and interpreting online results.

You communicate complex technical ideas clearly and work effectively with cross-functional partners.

What we offer

You will work on recommendation problems with direct, measurable impact on how customers discover relevant content. You’ll collaborate with experienced scientists and engineers across DoorDash, Deliveroo and Wolt, learning from multiple recommendation systems while helping shape the next generation of the experience.

Together with your lead, you will have the opportunity to create a personalised development plan that builds on your strengths and develops new capabilities.
