About the Role

We are looking for an experienced Data Scientist Team Leader to lead and grow our data science team while delivering high-impact data science solutions for our clients. The role combines hands-on technical work with team leadership, focused on solving real business problems using classical machine learning techniques — building predictive models, uncovering patterns in data, and turning analytical insights into production-ready systems.

The Team Leader works closely with clients and internal engineering teams to understand business challenges, design appropriate modeling approaches, and deliver solutions that drive measurable value, while mentoring team members and owning the technical quality of the team's work. Candidates with additional experience in Generative AI and LLM-based systems will have a strong advantage, as we increasingly combine classical ML with modern GenAI capabilities.

Experience

• Several years of hands-on experience as a Data Scientist
• Proven track record of building and delivering ML models that reached production
• Experience working directly with business stakeholders and translating their needs into data science solutions
• Experience leading or managing a team of data scientists or analysts and owning their delivery

Required Expertise

• Strong command of classical machine learning algorithms — XGBoost, Random Forest, gradient boosting, regression methods, and clustering techniques
• Solid understanding of statistics, probability, and core ML theory
• Proficiency in Python and the standard data science stack (pandas, scikit-learn, NumPy)
• Experience with feature engineering, model validation, and handling real-world messy data
• Familiarity with SQL and working with structured data at scale
• Experience deploying or supporting models in production environments
• Proven experience leading, mentoring, or managing a team of data scientists or analysts
• Hands-on experience with Generative AI and large language models
• Familiarity with RAG architectures, vector databases, and embeddings
• Experience with LLM orchestration frameworks such as LangChain or LlamaIndex
• Experience combining classical ML approaches with GenAI solutions
