At ABB , we help industries run leaner and cleaner—and every person here makes that happen. You’ll be empowered to lead, supported to grow, and proud of the impact we create together. Join us and help run what runs the world. This position reports to: Team Leader - Optimax __ Job Responsibilities Developing and configuring mathematical models of industrial energy and process systems for ABB OPTIMAX optimization applications. Translating real plant behavior, operating limits, efficiencies, equipment dependencies, and operational requirements into Modelica-based engineering models. Working with systems such as boilers, gas and steam turbines, cogeneration units, steam networks, electrical grids, renewable generation, battery storage, and other industrial utilities. Analyzing process documentation, equipment data, operating curves, historical data, and customer requirements to define appropriate model parameters and constraints. Validating model behavior against real plant operation and identifying differences between expected and actual performance. Supporting the definition of optimization inputs, operating limits, costs, and process constraints. Troubleshooting model behavior and optimization results together with project engineers and technical specialists. Collaborating with customers, process experts, project managers, and international ABB teams. Participating in testing, commissioning, and tuning of optimization applications for industrial and energy customers. Contributing to the development and continuous improvement of standard OPTIMAX models and modelling practices. Who We Are Looking For You have a university degree in process engineering, energy engineering, mechanical engineering, chemical engineering, electrical power engineering, control engineering, or a related technical field. You have a good understanding of industrial or energy processes and basic engineering principles such as mass and energy balances, equipment efficiency, operating limits, and equipment dependencies. Experience with boilers, turbines, cogeneration, steam systems, power generation, industrial utilities, renewable generation, or energy storage is a strong advantage. You are comfortable working with equations, characteristic curves, engineering calculations, and technical documentation. Experience with Modelica, Dymola, OpenModelica, MATLAB/Simulink, Aspen, EBSILON, or another engineering modelling environment is an advantage. Knowledge of mathematical optimization, objective functions, decision variables, and constraints is an advantage, but not a requirement. You have strong analytical skills and enjoy understanding how complex technical systems behave. You have fluent English, including the ability to work with technical documentation and communicate in an international project environment. You are proactive, structured, communicative, and able to work independently as well as collaboratively. You enjoy working directly with engineers and customers to transform real operating requirements into reliable technical models. You want to develop your expertise in industrial energy optimization, Modelica, and advanced digital solutions.
