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 / Gurobi Py
  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 / Gurobi Py
  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.
