Informacje o stanowisku

We are a team of tech and data enthusiasts on a mission to bring together the best minds in IT and analytics. Our goal? To build cutting-edge analytical hubs that empower our partners to become truly data-driven organizations.

We are currently looking for a Senior Data Scientist to lead the design, development, and deployment of advanced analytical solutions within the Global Analytics Unit — a centralized, global team driving smart data products across all business areas.

This is a high-impact role for someone who thrives on end-to-end ownership: from exploratory data analysis and model design, through refactoring and stability testing, to production deployment and performance monitoring.

Why join us

If you’re looking for an opportunity to:

• Tackle complex, real-world business challenges using advanced analytics and machine learning
• Build and deploy production-grade models that shape decisions across global markets
• Work with an exceptional international team of Data Scientists, ML Engineers, and Data Engineers
• Influence architectural and methodological decisions in a rapidly growing global analytics organization
• Operate in an environment that values autonomy, innovation, and technical excellence

…this might be the perfect fit for you.

You’ll also enjoy:

• Flexible working hours and remote/hybrid work model
• Private medical care and Multisport card
• Access to online learning platforms, certifications, and global knowledge exchange
• A relaxed, non-corporate atmosphere with genuine respect for expertise and ownership
• A modern office in central Warsaw with great transport links

As a Senior Data Scientist, you will take ownership of developing and productionizing advanced data science models and services. Your work will go far beyond notebooks — you’ll help design stable, reproducible, and automated ML pipelines.

In short

We’re looking for a Senior Data Scientist who’s not just great at modeling — but who writes clean, production-ready Python, builds pipelines that last, and obsesses over model robustness, automation, and stability.

You’ll join a team where experimentation meets engineering — and where your models will directly shape global business decisions.

What we expect

• 5+ years of professional experience in Data Science or ML Engineering, including production deployments
• MSc or PhD in Computer Science, Statistics, Mathematics, Physics, or related technical field
• Strong Python programming skills, including software engineering practices (OOP, modular code design, testing)
• Solid experience with ML frameworks and NumFOCUS stack: pandas, scikit-learn, SciPy, Matplotlib, NumPy
• Hands-on experience with PySpark and large-scale data processing
• Familiarity with Azure cloud ecosystem (Databricks, ML Studio, Data Factory, Azure DevOps)
• Understanding of CI/CD and MLOps pipelines, containerization (Docker, Kubernetes), and model deployment
• Experience designing robust validation and monitoring strategies for ML models in production
• Strong analytical mindset, excellent problem-solving skills, and the ability to think critically about model behavior
• Fluency in English (spoken and written), as you’ll collaborate globally

Nice to have

• Experience with Infrastructure as Code (Terraform)
• Familiarity with DBT for data transformation
• Knowledge of deep learning frameworks (TensorFlow, PyTorch)
• Experience working in agile, cross-functional environments
• Exposure to multi-tenant or global-scale data systems
