Join a team where data science fuels smarter e-commerce and marketing automation. You'll take end-to-end ownership of machine learning solutions — from concept to production — shaping customer experiences and driving measurable value across a fast-evolving product ecosystem.

Job Responsibility

  • Owning full model lifecycle: from research, experimentation and prototyping to deployment and monitoring
  • Building and optimizing machine learning models using Python e.g., customer lifetime value models, AI modules that support the recommendation engines and the use of a customer data platform
  • Designing data pipelines and integrating ML solutions into production (search personalization, clickstream analysis, email triggers)
  • Improving and maintaining existing models to ensure performance, scalability, and robustness in production
  • Collaborating closely with engineering, product and business teams to turn complex data into actionable product features
  • Upholding high development standards by writing clean, maintainable code, conducting code reviews, and embracing DevOps practices like testing and CI/CD
  • Contributing to the continuous improvement of the team by mentoring junior colleagues and bringing new perspectives to modeling and methodology discussions

Requirements

  • Experience in end-to-end data science projects (preferably in eCommerce, SaaS, MarTech space), around 5 years of experience
  • Strong background in Python
  • Experience deploying models in production environments
  • Experience with Azure infrastructure, including Kubernetes and Azure Pipelines
  • Solid understanding of statistics, modeling, and software engineering practices
  • Analytical mindset with a passion for practical impact, not just research
  • Excellent English and communication skills
  • Strong communication skills, with the ability to explain data-driven insights to diverse audiences
  • An ability to take charge of your own projects as well as close collaboration with others

Nice to have

  • Experience with: Azure, DevOps, Docker, Kubernetes, Databricks, Cassandra, SQL
