Math Modeler

The team of Wärtsilä marine engineering simulators is looking forMath Modeller. You can become part of a team which works on a market leader product (45% market share) that imitates marine engineering functionality for vessels. The preferred location for this position is Helsinki, Finland but also Turku, Finland is negotiable. We offer a possibility to hybrid work.

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.
• Practical experience in imitation modelling of physical systems.
• Basic knowledge of numerical methods for solving PDE and DAE.
• Basic knowledge of OOP approach or any OOP language.
• Be able to formulate a problem correctly and plan ways to solve it.
• English intermediate or higher.
• Be agile.

We will be amazed if you have (but not mandatory):

• Be familiar with Open Modelica or any Modelica-based language.
• Be able to quickly master new tools.
• Have a background in marine engineering.

Practical experience in imitation modelling required in one of the areas:

• Hydraulics (gravity flow, pumping through pipeline, pump characteristics, pipeline elements resistance, Bernoulli equation, two-phase media flow (liquid + gas)).
• Heat Transfer (heat capacity of materials – solid, liquids, gases; heat exchange between various media; temperature transfer & temperature resistance of materials).
• Thermodynamics (ideal gas laws; real gas specifics; main thermodynamics parameters and characteristics, its interdependencies; thermodynamics laws; phase transitions).
• Mechanics (kinematics and dynamics of rigid body, rotational dynamics equations; mechanical energy parameters and equations, mechanical energy transitions, inertia characteristics; simple mechanisms).
• Automation and regulation (main principals and parameters; governors (controllers) – main types and work principals; controlled system parameters and dynamic).

Why you and us? We at Wärtsilä believe in empowerment, ownership and taking responsibility of our work. We support each others growth, and co-creation is the true basis of our innovation. We have courage to see opportunities and take initiative. We are authentic and honest, and we strongly believe in that by being your own true self you can accomplish so much more.
