Location: Singapore
Workplace: Onsite
Employment Type: Full time
Job Function: Data Science & Machine Learning
Seniority: Graduate level

Key Responsibilities

  • •Model user demand elasticity across products and coupon values and use operations research optimization to find optimal budget allocation under constraints, maximizing GMV and conversion rate.
  • •Design globally optimal allocation and pricing algorithms using elasticity modeling for large-scale, budget-efficient scenarios.
  • •Integrate real-time item-wise voucher capabilities into recommendation pipelines across short videos, live streaming, and marketplace to enable joint “traffic + subsidy” optimization.
  • •Research and productionize causal inference and frontier AI technologies (uplift modeling, E2E modeling, RL, LLMs, AI agents) to improve user conversion and repeat purchase behavior.
  • •Collaborate in an algorithm team responsible for global e-commerce promotion algorithms that drive scaled growth in MAC and GMV.

Key Requirements

  • •Completing or recently completed a PhD in Computer Science, Mathematics, Statistics, Operations Research, or a related field, with strong algorithms and data structures foundations.
  • •Strong expertise in machine learning and deep learning, with familiarity with models used for recommendation, advertising, search, or marketing.
  • •Hands-on experience in at least one area: causal inference/uplift modeling, operations research optimization, search/recommendation/advertising algorithms, or frontier AI technologies (LLMs/AI agents/generative recommendation).
  • •Experience with operations research methods such as linear programming, integer programming, dynamic programming, or MCKP for optimization and budget/pricing algorithms (preferred).
  • •Excellent business acumen and the ability to translate complex business problems into mathematical/algorithmic models and productionize them.
