Hybrid Prescriptive AI Optimization Scientist

Pigment; Greater London; Hybrid; GBP 90,000 - 130,000; Full time

Job summary

Pigment is hiring an Optimisation AI Scientist to own the technical delivery of our solver pilot programme and establish production-grade optimisation capabilities that move customers from descriptive to prescriptive planning.

You will lead client problem formulation, guide implementations, and collaborate with Solutions Architects to ensure impactful results across pilots. This hybrid role blends analytics with customer-facing work.

Qualifications

• Demonstrable experience formulating and solving optimisation problems for real-world operational use cases.
• Proficiency in Python with hands-on experience in a major solver library (Gurobi, OR-Tools, CPLEX, HiGHS, or equivalent).
• Experience with supply chain/operations data — SKUs, BOMs, capacity constraints, service levels, lead times, inventory targets etc.
• Understanding of core OR techniques: branch-and-bound, LP relaxation, constraint programming, sensitivity analysis
• Degree in Operations Research, Applied Mathematics, Industrial Engineering, CS, or related field (MS/PhD advantageous)

Responsibilities

• Formulate supply chain optimisation problems as rigorous mathematical models - objective functions, costs, penalties, and constraints
• Configure and run optimisation models for customer pilots and implementation, and support Solutions Architects in delivering results and debriefs
• Build and run Python models against third-party solvers across multiple dataset scales, and benchmark results across use cases
• Work with Engineering and Data Science leads to define the path to production-grade solver integration and customer specific implementations within Pigment's architecture
• Engage technically with solver vendor teams during partnership evaluation
