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).

For very strong candidates, we may consider a fully remote working arrangement from anywhere in Italy.**

**In this role, you will make an impact in the following ways:**

+ You will combine high-fidelity **3D CFD/kinetics with 1D system-level modelling to assess Aftertreatment system architectures** and support design optimization.
+ You will perform **Chemical Kinetics modelling** and conjugate heat transfer analysis to improve the performance and durability of **critical Aftertreatment components.**
+ You will 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.
+ You will develop and apply 3D CFD/kinetics models and simulation workflows for current and future compression ignition and spark ignition engine technologies.
+ You will investigate thermal-fluid product or technology issues, identify root causes, recommend corrective actions, and document results to support problem resolution.
+ You will contribute to platform engineering development programs by helping fulfil open-loop and closed-loop Aftertreatment simulation requirements.
+ You will strengthen analysis-led product development by improving modelling, simulation, testing, and data-analysis processes.
+ You will 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, Python, Tecplot, Ensight, Paraview, or equivalent software.
+ Effective collaboration, communication, problem-solving, documentation, and decision-making skills to work across teams and support project execution.

**Education/ Experience:**

+ Bachelor’s degree in Engineering or an appropriate STEM field is required.
+ Master’s degree or PhD in Mechanical Engineering or a related thermal-fluid discipline is preferred or may be required for select roles.
+ Minimum of 2 years of academic experience in Aftertreatment modelling is preferred.
+ Experience with diesel combustion system architecture analysis is strongly preferred.
+ Internship, co-op, extracurricular technical project, or early-career professional experience in a relevant engineering discipline is preferred.
+ Knowledge of Microsoft Office tools and familiarity with technical documentation, requirements engineering, and product development processes will support success in the role.

**Please note that the salary range provided is a good faith estimate on the applicable range.

The final salary offer will be determined after considering relevant factors, including a candidate’s qualifications and experience, where appropriate.**
