We are looking for a talented Thermal and Fluid Systems Engineer to join our team specializing in engineering in Milano, Lombardia, Italy . This position follows a hybrid work model (60% on-site / 40% remote). In this role, you will make an impact in the following ways: Combine high-fidelity 3 D CFD/kinetics with 1 D system-level modelling to assess aftertreatment system architectures and support design optimization. Perform chemical kinetics modelling and conjugate heat transfer analysis to improve the performance and durability of critical aftertreatment components. Use thermal, fluid sciences and chemical kinetics to evaluate system and component performance, helping guide technical decisions that support advanced, efficient, and environmentally responsible products. Develop and apply 3 D CFD/kinetics models and simulation workflows for current and future compression ignition and spark ignition engine technologies. Investigate thermal-fluid product or technology issues, identify root causes, recommend corrective actions, and document results to support problem resolution.



Contribute to platform engineering development programs by helping fulfil open-loop and closed-loop aftertreatment simulation requirements. Strengthen analysis-led product development by improving modelling, simulation, testing, and data-analysis processes. Collaborate with engineers, technical leaders, project teams, suppliers, and other stakeholders to deliver clear recommendations that support high-quality project decisions. To be successful in this role you will need the following: Strong technical fundamentals in thermodynamics, chemical kinetics, fluid dynamics, heat transfer, aftertreatment performance, and energy conversion systems. Practical experience using modelling and simulation tools such as CONVERGE, Chemkin, GT‐Suite, Fluent, Boost, GT‐XChem, Exothermia suite or similar thermal‐fluid analysis platforms. Strong data analysis and visualization skills using tools such as MATLAB, Pyt
