Thermal and Fluid Systems Engineer

Thermal and Fluid Systems Engineer

Cummins

Milan, Turin or Remote, Italy

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

• You will use thermal and fluid sciences 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 combustion models and simulation workflows for current and future compression ignition and spark ignition engine technologies;
• You will combine high-fidelity 3D CFD with 1D system-level modelling to assess combustion system architectures and support design optimization;
• You will perform in-cylinder combustion and conjugate heat transfer analysis to improve the performance and durability of critical engine power-cylinder components;
• 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-cycle and closed-cycle combustion 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, combustion, fluid dynamics, heat transfer, engine performance, and energy conversion systems;
• Practical experience using modelling and simulation tools such as CONVERGE, Chemkin, GT-Suite, Fluent, Boost, 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 in-cylinder 3D combustion CFD analysis 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.
