Job description

Are you ready to be part of the exiting journey to take the internal combustion engine to the next level by using renewable and carbon neutral fuels in conventional combustion engines?

In the position as Simulation engineer you will:

Propose future engine concept by doing simulation studies in different stages of the development work with input from projects and other stakeholders. This means that you will set up, calibrate and perform gas exchange simulations using in-house software (ICES), as well as commercial software (GT-Power).
Cooperate with the engine and component testing teams. This is essential and is a natural part of your daily activities since gas exchange model correlation/calibration is typically based on test data.
In order to ensure that we can meet the coming challenges, we need to continuously update methods and propose development of our way of working.

• Master of Science in engineering
• Education/training in internal combustion engines
• Experience of GT Power or similar programs is an advantage
• Programming experience at a high level in for example Matlab, Python or similar.
• Fluent in English, written and spoken.
