Mid Data Engineer on-site Warsaw or remote outside

About the Role

We’re on the lookout for a skilled Data Engineer to help advance the foundation of our internal data systems. This position sits within a team focused on enabling data access and reliability across the organization — from analytics and machine learning to business insights and reporting. You'll play a central part in shaping the tools and processes that allow others to work with data efficiently and securely.

The role combines backend development for data handling, integrating external and internal datasets, maintaining infrastructure, and promoting high-quality, trustworthy data across the business. You’ll operate in a collaborative and agile setting, frequently engaging with engineering peers, analysts, and operational teams.

What You’ll Be Doing

• Take ownership of components within our internal data environment — from data storage systems to processing layers.
• Design and oversee automated data workflows, ensuring that the flow of information is timely, consistent, and trustworthy.
• Manage access controls, permissions, and metadata across the data ecosystem.
• Build connections between various internal tools and external platforms to centralize data access and processing.
• Assist the analytics and business teams in shaping clean, reusable data models.
• Work closely with other engineers, DevOps, QA, and analysts to ship reliable data features into production.
• Refine and enhance operational guidelines, improving how we maintain and monitor data systems.

What We’re Looking For

• 2–3 years of experience building large-scale data processing systems using distributed technologies.
• Strong Python skills applied in real-world data engineering work, with good software development habits.
• Familiarity with task orchestration and data workflow tools.
• Cloud experience — AWS, GCP, or Azure — with an understanding of scalable storage and compute.
• Solid grasp of SQL, database internals, and design patterns for data transformation (ETL/ELT).
• Comfortable working in English in a professional environment.

Bonus Points If You Bring:

• Exposure to Databricks, Azure Data Services, or CI/CD pipelines via Azure DevOps.
• Experience working in hybrid teams or remote-first environments.

What We Offer

• Immediate start, with long-term employment planned after a short-term trial.
• Work from anywhere in Poland — hybrid or fully remote (4 office days/month optional).
• Flexible working hours tailored to your schedule.
• Annual wellbeing support budget.
• Mental health assistance available from day one.
• Professional growth via training and learning programs.
• Recognition programs and team-driven initiatives.
• Health and life insurance packages (optional or co-financed).
• Multisport, lunch card, and lifestyle benefit platform.
• Budget for electricity and internet costs when working from home.
• Opportunities to work abroad remotely under certain conditions.
• Extra day off to volunteer and support causes you care about.
