Sr. Principal Engineer

Job Description:

We are seeking a Senior Principal Engineer to lead advanced AI‑driven optimization initiatives for complex logistics systems. This role is responsible for designing, modeling, and solving large‑scale optimization problems that directly impact operational efficiency, cost, and scalability across logistics and supply‑chain applications.

The ideal candidate combines deep academic rigor in optimization with hands‑on industrial implementation experience, and can act as both a technical authority and architect for optimization‑based AI solutions.

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

• Strong understanding of logistics and supply‑chain optimization problems

• Advanced Python programming skills for model development and integration.

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.
