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.
Key Responsibilities
- 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)
Skills, Knowledge and Expertise
- 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
- 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
