About The Position

We are hiring a Staff or Senior Applied Scientist to build and deploy advanced AI/GenAI and ML systems grounded in applied mathematics and Operations Research (OR). This role is ideal for someone who can take ambiguous, high-impact operational problems, turn them into clear mathematical/algorithmic formulations, and lead implementation end-to-end—including writing production-quality code.
You’ll work at the intersection of optimization, inference science, NLP, and reinforcement learning, with a strong emphasis on practical delivery and measurable business outcomes. Supply chain optimization experience is a plus.

Requirements

• Strong applied mathematics background with depth in Operational Research, including one or more of: Linear / Mixed-Integer Optimization (LP/MIP)
• Constraint Programming
• Network / Graph Optimization
• Stochastic / Robust Optimization
• Simulation, heuristics, or metaheuristics
• Research or applied experience in at least one of: Inference science (e.g., causal inference, Bayesian methods, uncertainty modeling)
• NLP (e.g., retrieval, embeddings, information extraction, LLM systems)
• Reinforcement Learning (e.g., bandits, sequential decision-making, offline RL)
• Proven ability to implement algorithms and deliver real systems end-to-end.
• Strong coding skills in Python and familiarity with relevant scientific/ML tooling.

Nice To Haves

• Experience in supply chain optimization (planning, inventory, logistics, fulfillment, scheduling).
• Experience building GenAI/LLM-enabled decision systems (e.g., RAG, tool-augmented agents, evaluation frameworks).
• Background shipping applied science solutions into production environments.

Responsibilities

• Problem formulation: Translate business challenges into mathematical and computational models.
• Applied research: Evaluate and adapt existing approaches (OR models, AI/ML, GenAI/LLM methods).
• Algorithm development: Design and implement new algorithms when existing solutions fall short.
• Hands-on execution: Build prototypes, run experiments, and lead production implementation (you code).
• Technical leadership: Drive solution architecture, performance evaluation, and operational readiness.
• Collaboration: Partner with product, engineering, and domain teams to deliver scalable solutions.

What This Job Offers

• Job Type: Full-time
• Career Level: Mid Level
• Education Level: Ph.D. or professional degree
• Number of Employees: 501-1,000 employees
