    Hello!

     

    We are E-Com, a team of Foodtech and Ukrainian product lovers.

    And we also break stereotypes that retail is only about tomatoes. Believe me, the technical part of our projects provides a whole field for creativity and brainstorming.

     

    What we are currently working on:

    • we are upgrading the existing delivery of a wide range of products from Silpo stores;

    We are developing a next-generation Decision Support Platform that connects demand  planning, operational orchestration, and in-store execution optimization into one unified Analytics and  Machine Learning Ecosystem. 

     

    The project focuses on three major streams: 

    •  Demand & Forecasting Intelligence: building short-term demand forecasting models, generating  granular demand signals for operational planning, identifying anomalies, and supporting commercial  decision logic across virtual warehouse clusters. 

    •  Operational Orchestration & Task Optimization: designing predictive models for workload  estimation, task duration (ETA), and prioritization. Developing algorithms that automatically map  operational needs into structured tasks and optimize their sequencing and allocation across teams. 

    •  In-Store Execution & Routing Optimization: developing models that optimize picker movement,  predict in-store congestion, and recommend optimal routes and execution flows. Integrating store  layout geometry, product characteristics, and operational constraints to enhance dark-store  efficiency. 

     

    You will join a cross-functional team to design and implement data-driven decision module that directly  influence commercial and operational decisions.

    •  develop routing and path-optimization models to improve picker movement efficiency within dark  stores; 

    •  construct data-driven decision modules that integrate commercial rules, operational constraints, and  geometric layouts;

    •  translate business requirements into ML-supported decision flows and automate key parts of  operational logic; 

    •  build SQL pipelines and data transformations for commercial, operations, and logistics datasets;

    •  work closely with supply chain, dark store operations, category management, and IT to deliver  measurable improvements;

    •  conduct A/B testing, validate model impact, and ensure high-quality model monitoring. 

     

    Requirements:

    •  bachelor’s Degree in Mathematics / Quantitative Economics / Econometrics / Statistics / Computer  Sciences / Finance; 

    •  at least 2 years working experience on Data Science; 

    •  strong mathematical background in Linear algebra, Probability, Statistics & Optimization Techniques; 

    •  proven experience with SQL (Window functions, CTEs, joins) and Python;

    •  expertise in Machine Learning, Time Series Analysis and application of Statistical Concepts  (Hypothesis testing, A/B tests, PCA); 

    •  ability to work independently and decompose complex problems. 

     

    Preferred:

    •  experience with Airflow, Docker, or Kubernetes for Data Orchestration; 

    •  practical experience with Amazon SageMaker: training, deploying, and monitoring ML models in a  production environment; 

    •  knowledge of Reporting and Business Intelligence Software (Power BI, Tableau, Looker); 

    •  ability to design and deliver packaged analytical/ML solutions. 

     

    What we offer

    • competitive salary;
    • opportunity to work on flagship projects impacting millions of users;
    • flexible remote or office-based work (with backup power and reliable connectivity at SilverBreeze Business Center);
    • flexible working schedule;
    • medical and Life insurance packages;
    • support for GIG contract or private entrepreneurship arrangements;
