Senior Optimization Specialist

Optimization Models, Logistics, Heuristics

Are you an experienced optimization expert? Join our client to help define and design a complex, multi-constraint optimization model that will drive store replenishment decisions for thousands of products — and evolve into a scalable, commercial-grade solution.

Start

During December 2025 or January 2026

Duration

4 weeks

Location

Helsinki, Hybrid

Allocation

100%

This project is planned as a 4-week engagement during December–January, working closely with an experienced internal team that includes a top-level Data Scientist and a Solution Architect. You will be part of shaping the technical strategy and exploring different modeling and heuristic approaches for handling multiple simultaneous constraints.  The project’s goal is to plan a productizable optimization engine that calculates replenishment orders for several difeerent products while considering logistical constraints such as transport capacity, delivery schedules and warehouse limitations. 

Required Skills:
  • Proven experience developing mathematical optimization and computation models (e.g., linear/integer programming, heuristics, simulation)
  • Deep understanding of logistics, replenishment, or supply chain optimization
  • Ability to structure complex business problems and translate them into solvable mathematical models
  • Strong collaboration and communication skills, fluent in English
  • Bonus: experience in turning optimization frameworks into scalable or commercialized products (e.g., APIs or services)
