Senior Data Scientist, Campaigns

We’re looking for a seasoned Data Scientist to architect the next generation of our campaign optimization systems. You will design and scale the logic that determines which users to target and which incentives to deploy to maximize investment efficiency. If you’re excited to apply Machine Learning and Causal Inference to drive global impact, join us!Locations: Tallinn, Estonia | Berlin, Germany

About the role

You’ll own Bolt’s campaign optimization systems end-to-end, architecting the "brain" that determines how we allocate rider and driver incentives globally. As a Senior Data Scientist, you will be the driving force in elevating our technical standards, pioneering solutions that bridge the gap between academic research and product development. You will serve as a technical "North Star"—mentoring colleagues and setting the bar for rigorous, maintainable data products that directly shape the experience of over 200 million customers worldwide.

Main tasks and responsibilities:

Lead the technical vision for our campaign optimization roadmap, translating high-level objectives into data science products.
Architect and deploy end-to-end uplift models and optimization systems that maximize our investment efficiency.
Design and execute advanced experimentation frameworks to reliably measure campaign incrementality.
Set the gold standard for technical excellence by championing rigorous statistical and engineering practices.
Serve as a mentor and advisor on highly technical challenges.
Partner with Product, Engineering, and Operations to identify opportunities and develop pragmatic solutions that solve intricate business problems.

About you:

Pragmatic problem solver, able to work autonomously from research to production deployment.
5+ years of experience in applied ML; experience in a growth role (marketplace pricing or incentives) is a plus.
Exceptional knowledge of ML, statistics with hands-on experience in causal inference/ML.
Expert proficiency in Python and SQL.
A natural mentor who enjoys leveling up those around you and can explain the "why" behind complex mathematical concepts.

Experience is great, but what we really look for is drive, intelligence, and integrity. So even if you don’t tick every box, please consider applying!
