About the role

As a Senior Data Scientist at Kard, you will build and deploy machine learning and experimentation systems that power our card-linked offers platform. Your work will directly improve how users discover and engage with offers, and how partners measure ROI. You’ll operate across personalization, ranking, and causal measurement - partnering closely with Product, Engineering, and Sales to turn behavioral transaction data into production-grade models and insights.

What they're looking for

  • 6+ years of experience in data science, with meaningful experience in applied machine learning in production
  • Strong experience with recommendation systems, ranking models, or personalization (e.g., propensity models, collaborative filtering, embeddings)
  • Solid grounding in statistics and experimentation, including A/B testing and incrementality measurement
  • Experience with causal inference approaches for real-world observational data
