Team of Wartsila marine engineering simulators is looking for mathematical modeler. You can become part of a team which works on a market leader product (45% market share) that imitates marine engineering functionality for vessels.

This permanent position is in Belgrade, Serbia.

Main responsibilities:

• Develop from the scratch for dynamic math models of vessel equipment and systems.
• Create front-end side of simulators.
• Compile technical documentation for these models.
• Maintain existing models.
• Take a part in agile activities.

To be successful in this position, we expect you to:

• Bs or MS in physics, applied math, engineering or similar field.
