Sr. Principal Engineer

Key Responsibilities

• Lead the design and implementation of optimization models for large-scale logistics and supply-chain problems (e.g., routing, scheduling, network design, capacity planning).
• Develop and maintain optimization formulations using Python-based modeling frameworks such as: Gurobi / GurobiPy Pyomo.
• Select, implement, and tune appropriate optimization algorithms, including: Linear Programming (LP), Mixed-Integer Linear Programming (MILP), Non-Linear Programming (NLP).
• Translate complex real-world logistics constraints into mathematically rigorous and computationally efficient models.
• Collaborate with AI, data science, and system engineering teams to integrate optimization engines into production AI platforms.
• Evaluate solver performance and scalability; optimize model performance for real-time or near-real-time decision-making.
• Provide technical leadership, mentoring, and design reviews for optimization engineers and researchers.

Required Qualifications

• PhD in Optimization, Operations Research, Applied Mathematics, Industrial Engineering, or a closely related field.
• Deep expertise in mathematical optimization modeling and algorithmic design.
• Strong hands-on experience with: Gurobi / GurobiPy Pyomo.
• Proven knowledge of and practical experience with: LP, MILP, and NLP formulations.
• Solver behavior, numerical stability, and computational complexity.
• Advanced Python programming skills for model development and integration.
• Strong understanding of logistics and supply-chain optimization problems.

Preferred (Nice-to-Have) Qualifications

• Experience applying optimization techniques in autonomous systems, including: Motion planning, Trajectory optimization, Autonomous vehicle or robotics applications.
• Familiarity with hybrid approaches combining optimization and machine learning.
• Experience deploying optimization-based decision engines in production environments.
