  • Competence in computer tools
  • Good communication skills in English are essential and capability to communicate in Finnish is beneficial
  • Positive attitude for collaborative work
  • Previous knowledge/experience of reactor physics, nuclear fuel behaviour, thermal mechanics, or experimental research work are considered as assets.

As a person, we hope that:

  • You have good networking skills, and you enjoy working in a multidisciplinary research environment
  • You deliver according to the targets and take responsibility of your actions
  • You are a problem solver with scientific curiosity and proactive attitude
  • You are flexible in reorientating to new scientific problems or customer needs.

We appreciate ambition and willingness to learn over having all the answers or skills ready when you start.

What would we offer you?
