MDB Engineer

Key Responsibilities:

 Develop and maintain accurate refrigerant component/system models, ensuring

alignment with product requirements.

 Participate in the full lifecycle of refrigerant component calculation development in C#

or Python, including specification, design, implementation, unit testing, accuracy

assurance, integration with .NET APIs, and maintenance.

 Design, develop, and validate complex thermal models for refrigerant components, such

as heat exchangers, chillers, compressors, condensers, evaporators, and expansion

valves.

 Apply Model-Based Design (MBD) methodologies to develop, implement, and verify

real-time control systems for refrigeration systems and refrigerated display cabinets.

 Interpret simulation results to extract insights and inform design decisions.

 Collaborate with Product Owners and technical teams to troubleshoot and resolve

issues.

 Conduct model testing, calibration, and validation using experimental data.

 Work with global engineering design centers on challenging modeling problems,

promoting the use of simulation techniques to support design decisions.

 Demonstrate the ability to learn new modeling tools/inhouse tools quickly and apply

them effectively to solve complex engineering problems.
