Role Overview

As a Principal Data Scientist within Coupangs Supply Chain Management Autonomation (SCMA) organization you will serve as the scientific authority and primary architect for our Cognitive Engine. You will be the bridge between cutting-edge Deep Learning (signal sensing) and Operations Research (constraint-based optimization).

Your mission is to transform Coupangs supply chain into a durable competitive advantage by building a fully autonomous agentic operating system that is capable of multi-step reasoning where LLMs interpret signals and OR models execute procurement decisions without manual intervention. This system will manage procurement decisions for 10M units daily with the goal of reducing manual execution by 50%while maximizing inventory ROI and in-stock rates.

Key Responsibilities

• Architect the Cognitive Engine:Lead the synthesis of Large Language Models (LLMs) Knowledge Graphs (KGs) and Graph Neural Networks (GNNs) to create an autonomous agentic supply chain platform.
• Integrate DL & OR:Design hybrid systems that utilize Deep Learning for high-fidelity signal sensing and Operations Research for complex constraint-based optimization.
• Drive Full Autonomy:Develop models that proactively manage the entire SKU lifecycle at hyper-scale moving from human-in-the-loop to human-on-the-loop strategic oversight.
• Establish Model Governance:Implement strict governance frameworks to ensure high-stakes autonomous decisions remain accurate unbiased explainable and resilient to data drift.
• Simulate & Experiment:Lead Large-scale Discrete Event Simulations (DES) and Agent-Based Simulation models to validate what-if scenarios before production deployment.
• Strategic Leadership:Advise leadership on the research roadmap and technical breakthroughs that will define the future of e-commerce supply chain management .
• Cross-Functional Partnership:Partner with SCMA Engineering to deploy production-grade models that handle extreme demand volatility without compromising latency or reliability.

Qualifications & Technical Requirements

• Education:Ph.D. or Masters in Operations Research Computer Science (AI/ML focus) or a related quantitative field.
• Experience:10 years of relevant industry experience ideally in e-commerce SCM or high-complexity trading environments.
• AI/ML Expertise:Hands-on experience designing and implementing:
• Model Architectures:Experience with state-of-the-art time-series and graph architectures (e.g. TiDE GNNs Transformers) and experiences in Reinforcement learning models.
• Generative AI:Expert-level knowledge of LLMs and Agentic workflows.
• Graphs:Knowledge Graphs and Graph Neural Networks (GNNs) for supply chain mapping.
• Optimization & Heuristics:Deep proficiency in Mixed-Integer Programming (MIP) Dynamic Programming and Meta-heuristics (Genetic Algorithms PSO).
• Simulation Mastery:Proven track record in Discrete Event Simulation or Agent-Based modeling (e.g. AnyLogic Simio).
• Tooling:
• Solvers:Expertise in Gurobi Cplex or SCIP.
• Languages: Python Java or Scala.
• Data:SQL mastery and experience with Big Data environments (Spark Clickhouse).
