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.

Si prega di notare che la fascia retributiva indicata rappresenta un riferimento applicabile a questa posizione. L’offerta salariale finale sarà determinata sulla base di fattori rilevanti, incluse le qualifiche e l’esperienza del candidato, ove applicabile.
