Senior Data Scientist - Search

Remote or Berlin, Germany
Analytics & Data Science

For an online delivery platform like Wolt, data science is a big opportunity. Our business has grown to a level (and keeps growing) where machine learning models for user acquisition, demand prediction, delivery time prediction, dynamic pricing, operations optimisation etc. can have a huge impact. A more effective delivery platform will benefit everyone in our ecosystem: our 90 000+ courier partners, our merchants and our 10+ million consumers. We're looking for a Senior Data Scientist (Search) to join our competence team of 20+ data science and analytics professionals in Helsinki or Berlin. 


Data Scientists at Wolt are working with machine learning for the most important processes and parts of Wolt’s online delivery platform. The work consists of owning machine learning components as part of a product team; starting from identifying opportunities, to developing and prototyping a solution, all the way to deploying, maintaining, and improving a production-ready solution. We are using a variety of technologies and tools e.g. Python, SQL, Spark, Snowflake, AWS, Looker, Airflow, MLflow, Kafka, Jenkins, and Grafana to get the job done, and constantly looking for ways to improve how our data scientists work.


You would work as an embedded Data Scientist in our cross-functional Consumer Search product team and own that specific area together with the team. You’d closely collaborate with product leads, engineers, designers and fellow data scientists.

The team focuses on improving the search experience and the relevancy of both global and in-venue search results. You’ll have the opportunity to impact and shape the whole domain as the key expert from a data science perspective, tackling challenging problems in e.g. query understanding and ranking.


Our humble expectations

  • Ability to envision and implement a world-class search functionality for Wolt
  • Experience in working with real-world, large scale search or recommendation products in the domain of ecommerce or marketplace 
  • Plenty of hands-on experience with production level data science projects: all the way from prototyping to maintaining and improving production ready solutions - i.e. ability to handle a use case end to end
  • Deep understanding and experience with machine learning and solid understanding of (Bayesian) statistics 
  • Prior experience with ranking problems, query understanding and NLP
  • Knowledge of experimental design and analysis, and A/B testing
  • Degree or equivalent experience in a field relevant to data science
  • Fluent programming skills in Python (our main language for data science projects) and experience with databases (SQL, etc.)
  • Comfortable with a long enough list of tools and technologies to be effective in developing and deploying solutions. Ability to contribute to designing deployment architecture.
  • Analytical and curious thinker, self-starter with drive to get things done
  • Interest to contribute towards our Data Science team

Our offering to you  

  • You will be part of a team, which identifies themselves as Data Scientists, Data Analysts, and Business Intelligence Analysts. This means you will get a lot of peer support and sparring on your way growing as a data professional.  
  • The online delivery platform that Wolt is building will offer you interesting and complex challenges but also opportunities to create a big impact with your skills. Lots of geolocational and temporal data in real-time combined with differences in the economics and dynamics of the cities we operate in make Wolt a both challenging and also interesting company to practice analytics and data science. 
  • You would get to work in a company culture where we take ownership beyond the obvious, do common things uncommonly well, we think big but stay humble, do right by people, we treat others kindly and justly, recognise that if we don’t learn, we won’t stay still but fall behind and keep in mind that Luke was Yoda’s greatest achievement.
