Thermal and Fluid Systems Engineer

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:

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.
