• Collaborate with the Product Delivery Manager to translate business and operational needs into practical ML solutions

• Integrate ML components into the broader software ecosystem via APIs and backend services

• Take ownership of the ML/optimization domain, including experimentation, validation, iteration, and production deployment

• Contribute to architectural decisions focusing on scalability, maintainability, and long-term product development

Requirements

• Min. 6+ years of commercial experience in Machine Learning / Data Science roles

• Strong hands-on experience with Python and data libraries (NumPy, Pandas)

• Proven experience designing or implementing optimization algorithms, routing/scheduling systems, or decision support solutions

• Solid understanding of ML fundamentals, model evaluation, and real-world deployment constraints

• Experience working with structured and operational data for feature engineering and performance analysis

• Ability to work independently and take ownership in an evolving product environment

• Strong analytical and problem-solving skills with a practical, business-oriented mindset

• Experience integrating ML/optimization services with software products via APIs or data pipelines

• Senior-level communication skills and ability to cooperate effectively in a small, high-responsibility team
