Senior Data Engineer (PL) Zdalnie / Polska

A growing number of customers and integrations — in Poland and in the US — means growing complexity in the data architecture. We are looking for a senior to own the architectural decisions across the data engineering team, mentor the less experienced engineers, and make sure the pipelines scale with the company.

What you will do

• Making the key architectural decisions about the pipelines and the company-wide data model.
• Mentoring and backing up the less experienced data engineers, including on the team serving the US market.
• Running the most complex integrations with customer systems (ERP, WMS, ordering systems).
• Defining and enforcing the standards for data quality, security and performance across the company.
• Optimising the cost and performance of data processing at growing scale (Poland and the US).
• Working with the analytics and product teams on where the data platform goes next.

What we are looking for

• At least 4 to 5 years as a data engineer, including making architectural decisions independently.
• Fluency in SQL and experience with data warehouses (BigQuery, Snowflake, Redshift).
• Experience with pipeline orchestration tools (Airflow, Dagster or similar).
• Solid Python for building pipelines and transforming data.
• Experience supporting and mentoring other data engineers, formally or informally.
• English good enough to work in an international team, including with the US team.

Nice to have

• Experience with operational and production data (IoT, MES systems, data from production lines).
• Familiarity with dbt or similar transformation tools.
• Experience building a data platform from scratch, or substantially rebuilding one.

What we offer

• Real influence over the data architecture of the whole company — your decisions shape how data moves through the entire system, in Poland and in the US.
• Fully flexible remote work.
