You’ll work with process experts and end users to solve real production challenges using data, models, and decision support tools. To succeed, you’ll need curiosity and a practical mindset - plus the ability to connect how the mill works with how data can improve it.”

* Framing operational problems with process experts (goals, constraints, what “good” looks like)
* Exploring and validating production/process data and building usable datasets

* Understanding of industrial process operations (e.g., unit operations, process variability, basic process control) and motivation to learn pulp mill specifics fast
* Solid data analysis and programming skills (typically Python and common data/ML tooling)
* Ability to work with messy real-world data, validate assumptions, and communicate clearly with engineers and end users
* Structured working style: you define deliverables, document your work, and follow through

You should be comfortable using Finnish or Swedish  will onboard you to your tasks, as well as the rules and ways of working in our workplace. From your first day, you are a full member of our working community, and we encourage you to be active, learn, and ask questions about your work.
