Decision Scientist

This contract Decision Scientist role focuses on developing and improving analytical models for operational decision-making, working with existing Python pipelines and Databricks notebooks. The core requirements are hands-on Operations Research experience, especially LP/MILP formulation and infeasibility handling, applied ML/statistical modeling, strong maintainable Python, and experience with an optimization framework and solver. Candidates should have a relevant quantitative master’s degree and at least four years of analytical, OR, or ML solution-building experience. Supply chain, manufacturing, logistics, or procurement experience is useful; Databricks, Spark, Pyomo/GLPK, network modeling, and life-sciences supply chain exposure are preferred. The location is Poland and the engagement is contract; the work mode is not specified. Supply chain is presented as an ideal operating context rather than an exclusive industry requirement.

Responsibilities

What You'll Be Doing.

Every role at Ubique contributes directly to solving meaningful business challenges for our clients.

01

Develop and enhance mathematical optimization (LP/MILP), simulation, time-series, statistical/ML, and network-based analytical models as required by the use case.

02

Formulate analytical problems clearly, including decision variables, objective functions, constraints, assumptions, and appropriate treatment of infeasibility or trade-offs.

03

Work with existing Python analytical pipelines and Databricks notebooks; trace dependencies across data transformations, model logic, and downstream outputs before making changes.

04

Prepare and validate analytical inputs from demand forecasts, inventory, bills of materials, supplier data, and other operational datasets.

05

Develop, train, and evaluate ML models for applications such as classification, forecasting, anomaly detection, and ranking when supported by available data.

06

Validate solutions through appropriate testing, scenario/sensitivity analysis, and business-result reconciliation.

07

Write modular, maintainable, testable Python code; document model logic, implement regression tests, use version control, and troubleshoot data/model/runtime issues.

08

Collaborate with the Decision Science, Data Engineering, and Technology teams on implementation dependencies, testing, and production readiness.
