Job description

Engineering · Vaasa, Ostrobothnia, Finland · Full-time · Senior level

The role centers on building and running test systems that prove energy storage products work as intended. A strong candidate brings an engineering background, Python programming, and hands on skill with power supplies, electronic loads, measurement gear and environmental chambers. Planning tests, writing clear reports and automating both the testing and the reporting are core to the job.

How it fits the AI era

AI data centers are a main customer, so the products this engineer tests sit directly behind AI workloads. The testing itself is increasingly automated, with scripts and frameworks doing repeated runs and generating reports, which frees the engineer to design test plans and judge results. Careful measurement, sound judgment about failures and clear communication stay human.

How it builds AI experience

Working here builds experience testing power hardware that protects GPU clusters and grid stability, a niche tied to AI infrastructure growth. Automation work in Python, Robot Framework or pytest sharpens skills that carry into any hardware validation role. Learning the measurement and chamber control side deepens practical test engineering that AI tools cannot replace.

Worth showing

• Python test automation
• Robot Framework or pytest
