Freelance Middle+/Senior C++ Developer (Load Optimization Engine)

Middle+/Senior C++ Developer (Load Optimization Engine)

We are looking for a strong Middle+/Senior C++ Developer to join a high-performance optimization project in the supply chain and logistics domain.

The project focuses on building a load optimization engine responsible for generating efficient and execution-ready truckload plans while considering multiple real-world constraints such as weight, volume, loading sequence, stacking rules, item compatibility, warehouse limitations, and transportation feasibility.

This is not a typical backend/frontend CRUD project. The main focus is on algorithmic optimization, heuristics, mathematical modeling, and performance engineering.

Project Details

• Domain: Supply Chain / Logistics Optimization
• Client Location: USA
• Team Size: ~20 specialists

• Duration: 3–6 months

   

Requirements

Must Have

• 4+ years of commercial experience with C++
• Strong knowledge of algorithms and data structures
• Experience with performance-critical systems
• Strong understanding of optimization-heavy logic
• Experience with Linux development
• Experience with profiling and benchmarking
• Experience with unit testing
• Strong problem-solving and analytical skills

• Ability to discuss architecture, algorithms, technical trade-offs, and estimations in English

   

Nice to Have

• Mixed Integer Programming (MILP)
• Constraint optimization
• Bin packing / 3D packing algorithms
• Experience with OR-Tools, Gurobi, CPLEX, CBC, GLPK, or similar frameworks
• Experience with CMake
• GCC / Clang toolchain knowledge
• Python for prototyping or testing

• Experience in logistics, transportation, warehouse, routing, simulation, or other computation-heavy systems

   

Responsibilities

• Analyze technical and business requirements for the load optimization engine
• Design and implement optimization algorithms in C/C++
• Develop and improve performance-critical logic on Linux
• Optimize calculations for fast and scalable execution
• Work with constraints related to:
  • weight and volume
  • truck capacity
  • loading sequence
  • stacking rules
  • item compatibility
  • warehouse/site execution rules
• Translate mathematical and algorithmic concepts into production-ready solutions
• Create benchmarks, test cases, and performance validation scenarios
• Participate in technical discovery, estimations, and solution discussions
