Hey, you look like you might be our new ย Senior Data Scientist, Search

Analytics & Data Science

Helsinki, Finland

Full-time

Data Scientists at Wolt build and deploy applied data science models using a variety of approaches including data mining, statistical analysis, and machine learning for the most important processes and parts of Woltโ€™s online delivery platform and business operations that affect all the 23 countries we operate in. The work consists of owning machine learning use cases as part of a product or business team; starting from identifying opportunities, to developing and prototyping a solution, all the way to deploying, maintaining, and improving a production-ready solution inside of the embedded product team. We use a variety of technologies and tools including Python, SQL, Spark, Docker and K8s, Snowflake, Looker, Flyte, Seldon Core, Airflow, MLflow and Kafka to get the job done, and constantly looking for ways to improve how our data scientists work. ๐Ÿ’ช๐Ÿ’ช

We are looking for a data scientist to be embedded into our cross-functional Consumer Search team, to work together with engineers, product, design and analytics people, on developing algorithms and solutions for improving our search experience. The team owns the domain end to end, from developing approaches, to testing and understanding their impact, and to deploying and maintaining them under strict performance requirements.
