Job Level
About the role
- Lead the end-to-end delivery of logistics optimization projects, from problem definition and requirements gathering through model development, validation, deployment, and iteration.
- Develop and maintain optimization models using Linear Programming (LP) and Mixed Integer Programming (MIP) to solve real-world logistics, transportation, and network design problems.
- Implement optimization solutions using CPLEX, including model formulation, data preparation, solver integration, parameter tuning, and performance optimization.
- Write clean, maintainable, production ready Python code for model building, experimentation frameworks, data processing, and service integration.
- Collaborate with software engineering teams to integrate optimization models into production applications, ensuring reliability, observability, and maintainability.
- Partner with data engineering and analytics teams to access, shape, and validate high-quality datasets using SQL and Snowflake.
- Translate complex mathematical and operational concepts into clear insights for non‑technical audiences through effective storytelling and data visualization (e.g., Power BI, Python visualization libraries).
- Document model assumptions, constraints, design decisions, and handoff artifacts so engineering teams can operationalize solutions smoothly.
- Establish and promote best practices for optimization model development, including versioning, reproducibility, testing patterns, and scalable architecture.
- Collaborate cross‑functionally with product, operations, engineering, and business stakeholders to ensure alignment on goals, timelines, and implementation impacts.
- Support or lead prototyping of simple web‑based tools (where helpful) to accelerate proof‑of‑concept validation and stakeholder adoption.
Requirements
- 5+ years of real-world experience delivering end‑to‑end optimization solutions in production environments, ideally within logistics, transportation, supply chain, or large‑scale operational systems.
- Demonstrated ability to independently lead and deliver complex optimization initiatives
- Demonstrated mastery of Linear Programming (LP) and Mixed‑Integer Programming (MIP) model formulation, constraint design, feasibility analysis, and optimization trade‑offs.
- Hands‑on experience using CPLEX (or equivalent e.g. Gurobi) to solve complex modeling problems.
- Strong programming skills in Python, with experience writing clean, modular, testable code suitable for production usage.
- Solid experience with SQL and cloud‑based data warehouses such as Snowflake.
- Experience collaborating with software engineers and integrating optimization models into production systems, including familiarity with C#–based services and APIs.
- Proven ability to simplify and communicate complex technical concepts to less technical stakeholders through effective data visualization and presentation.
- Deep experience validating assumptions, constraints, and operational inputs to ensure models align with real‑world logistics workflows and constraints.
- Strong documentation habits and a track record of creating clear, maintainable artifacts for engineering handoffs.
- Ability to work effectively in a remote environment with stakeholders across engineering, operations, and product.
