We are looking for a Senior Applied Scientist (Matching) to design and evolve matching systems for our marketplace. You will develop matching as a real-time decision system, balancing supply, demand, and marketplace efficiency under uncertainty and dynamic conditions. Unlike traditional dispatch-based matching, our marketplace operates on a unique bid-based model, where rider-driver connections are shaped through direct negotiation. This creates a fundamentally different optimization problem, requiring advanced approaches to modeling user behavior, response dynamics, and marketplace incentives.
Design and improve matching and ranking algorithms, including supply/demand response and behavioral modeling
Frame matching as a decision system under uncertainty and real-time constraints
Develop, test, and deploy real-time matching and dispatching algorithms
Design and analyze A/B experiments to evaluate matching impact on marketplace efficiency and user experience
Productionize models in collaboration with engineering, ensuring scalability and robustness in high-load environments
Monitor system performance, including marketplace balance, feedback effects, and long-term matching quality
Contribute to methodological choices (e.g., discrete optimization, ranking, RL-inspired approaches)
3+ years of experience in Data Science, Applied Research, or algorithmic product optimization, preferably in marketplaces or matching/dispatch systems
Strong background in probability theory, mathematical statistics, discrete optimization, and causal inference
Proven ability to move from problem formulation to production-grade solutions
Proficiency in Python, SQL, and experience with production ML systems
Nice to Have
Experience with auction mechanics, economic models, or incentive-aware matching
Familiarity with online optimization, RL, or real-time decision systems
Experience working with large-scale, high-load production environments
Help us challenge injustice by creating fair choices for millions of people across 1100+ cities in 48 countries
Develop your professional skills with access to mentoring, career consulting, and learning programs
Collaborate with teams around the world and gain international experience through our Global Talent Exchange Program
Engage in company-wide challenges, awards, sports activities, employee-led social impact and volunteering projects
Work alongside people who take initiative, speak openly, and challenge themselves to grow
Improve your language skills through co-financed courses and internal speaking clubs
Salary from 70 700 EUR gross
Final benefits may vary depending on the location.
