About the role

Senior Data Scientist at Bitvavo focusing on causal inference, product personalization, pricing & execution, risk & financial integrity, and financial crime & compliance to drive evidence-based decisions across growth, product, markets, and risk.

Responsibilities

  • Own problems end to end: frame the question with the stakeholder, build the model or experiment, ship it, and follow it into production.
  • Work backwards from the decision. Start from what someone needs to decide and what it costs to get it wrong, not from the data that happens to be available.
  • Stay accountable for your models once they are live: monitoring, drift, retraining, and the day they start behaving differently.
  • Tell senior stakeholders things they do not want to hear, including that a campaign, a feature or a rule did not work.
  • Support your teammates in growing every day by setting the standard for how we do causal inference, reviewing their work, and sharing knowledge.

Qualifications

  • Strong applied experience turning a messy business question into a model or a measurement: causal inference where that fits, predictive and ranking models where it does not.
  • Fluency in Python and SQL, and comfort working independently rather than waiting for data to be handed to you.
  • We use Snowflake, dbt, Airflow and Looker, on top of technologies like MySQL, Druid, Kafka and Flink.
  • A track record of models that made it into production and changed a decision, not just notebooks and slide decks.
  • Sound statistical judgement, and the honesty to quantify and communicate uncertainty rather than hide it.
  • Exceptional communication skills. We expect you to talk to various stakeholders to derive requirements, drive discussions, and facilitate decision-making processes effectively.
  • Extraordinary sense of ownership.
