Senior Data Scientist

We are seeking a Senior Data Scientist with strong expertise in optimization and applied machine learning to support the development of large-scale decision systems in supply chain operations, including routing, scheduling, and resource allocation.This is a hands-on, execution-focused role working under the Data Science Lead. The successful candidate will own and enhance components of analytical and optimization models, ensuring they are scalable, reliable, and aligned with business needs. The role requires the ability to connect business requirements with data science solutions, operate in a fast-paced environment, and communicate effectively with both technical and non-technical stakeholders.Key Responsibilities
Develop and enhance optimization models using MILP and heuristic approaches, applying them to problems such as vehicle routing, scheduling, and resource allocation, and improving performance using solvers such as GurobiApply machine learning techniques to support decision systems, including predictive modeling, feature engineering, and generating inputs for optimization models, while ensuring strong integration between ML and optimization frameworksTranslate business requirements into structured analytical and optimization problems, incorporating operational constraints and clearly communicating model assumptions, trade-offs, and outcomes to stakeholdersDiagnose and resolve model issues including infeasibility, performance bottlenecks, and data inconsistencies, while analyzing trade-offs across cost, service level, and operational feasibilityDevelop and maintain data workflows using Python and SQL, and support scalable processing and deployment within cloud environments such as Azure and DatabricksEnsure data quality and model reliability by validating inputs, identifying gaps, and supporting feedback loops to improve model accuracy and alignment with operationsCollaborate with cross-functional teams, take ownership of model components, contribute to technical design discussions, and provide guidance to junior team membersQualifications
8+ years of experience in data science, operations research, or a related fieldStrong hands-on experience in optimization (e.G., MILP, VRP, scheduling) and machine learningProficiency in Python and SQLExperience working with optimization solvers such as GurobiFamiliarity with Azure and Databricks environmentsProven ability to translate business problems into data-driven solutionsStrong problem-solving skills and ability to work in fast-paced environmentsEffective communication skills with both technical and business stakeholdersPreferred Qualifications
