We are seeking a Senior Data Engineer position based in our Poznań location to join the Data Science & Engineering team.
Ready to help build a better future for generations to come?
In an ever-changing world, we owe it to ourselves and our future generations to live life responsibly. At ROCKWOOL, we work with dedication to enrich modern living through our innovative stone wool solutions.
Join us and make a meaningful difference!
Your future team:
You will join our Data Science & Engineering Team, a group of 12 skilled professionals including the Team Leader. The team combines strong expertise in data engineering, analytics, and machine learning, and is structured into several project‑focused sub‑teams working across a variety of business areas.
What we are building:
Our data platform is already there in cloud, already in Databricks. But we’re not here to maintain the status quo – we’re rebuilding it from the ground up to jump into exciting world of real-time data and streaming.
We will migrate from a batch-oriented Airflow + Databricks to a streaming-first architecture: Kafka, Databricks with new cool features like Declarative Pipelines, Unity Catalog, Apache Iceberg / Polaris Catalog, and new serving layer, which you will help us to select.
This is a greenfield build inside a global company – real budget, real data, real stakes. No startup chaos, but real room to make meaningful architectural decisions.
What you will be doing:
You'll be the go-to Databricks expert on the team. You'll have important role in the migration from the legacy stack while designing and building the new platform in parallel – and “in parallel” is doing real work in that sentence.
The legacy platform runs. Not beautifully, but it runs – and it serves real business needs that can't wait for the migration to finish. You'll split your time between keeping it stable (and gradually less painful) and building its replacement. If the idea of legacy firefighting makes you want to close this tab, this probably isn't the right role. If you see it as part of the job and take quiet satisfaction in fixing things that are broken – read on.

What we offer:
By joining our team, you become a part of the people-centric work environment of a Danish company. We offer you a competitive salary, permanent contract after the probation period, development package, team building events, activity-based office in Poznan’s city center in the new prestigious office building – Nowy Rynek. The building is recognized as a building without barriers, which means that it is fully adapted to the needs of people with disabilities.
Our compensation package on employment contracts includes:
… and while in the office you can also use modern office space with beautiful view and high standard furniture, bicycle parking facilities & showers, chill-out rooms with PlayStation, football table, pool table, board games, subsidized canteen with delicious food & fruit.
Interested?
If you recognize yourself in this profile and challenge, we kindly invite you to apply with CV written in English. If you want to include a short note on how you would approach a Databricks-based streaming migration, we would love to read it, too.
