Thermal and Fluid Sciences Engineering Co-Op Positions

You will analyze our products through simulation and physical testing to develop system level optimized solutions for IC engine & electric power systems, fuel & air systems, filtration & aftertreatment systems, and battery & fuel cell electric systems.

To do this you will be applying knowledge of fluid mechanics, heat transfer, thermodynamics, filtration, and combustion to assigned tasks to help integrate products & systems which deliver customer and regulatory requirements.

Roles available in Thermal & Fluid Systems include:

• Combustion and Emissions Systems Engineer (Hybrid)
• Aftertreatment Integration Engineer (Hybrid)
• Engine and Aftertreatment Simulation Engineer (Hybrid)
• Computational Fluid Dynamics Analyst (Hybrid)

In these applied science positions, you will utilize the core competencies of thermal and fluid sciences, employing and developing advanced analytical tools (including three-dimensional modeling) to answer key questions about the performance and architecture of a system or component. The results of this analysis drive decisions which ultimately lead to state-of-the-art, highly effective, environmentally friendly, and competitive products.

You will make an impact by:

• Analytically investigating product, system and/or technology problems and recommending appropriate actions for problem resolution and/or optimization
• Using your understanding of fundamental Physics to understand causal mechanisms, recommend appropriate action and assisting with documented problem resolutions.
• Actively collaborating with key stakeholders and colleagues, using analysis results to impact and support the successful advancement of projects
• Participating in problem resolution for moderately/high complex components, products, systems, subsystems, or services with a high degree of technical complexity and ambiguity and with accountability to the project team.

Using tools related to thermal and fluid sciences such as:

• Fluent (ANSYS Simulation ~ Simulink)
• GT-Suite
• Boost
• Converge (CFD Software
• Emissions data system
• Hardware in the loop testing
• MATLAB (with In-House developed plugins)

This role will not include management of people but could involve the coordination of work amongst employees.

To be successful in this role you will need to:

• Apply the principles of fluid dynamics, thermodynamics, energy conversion systems and heat transfer to real-world problems,
• Actively engage in product problem solving and product failure mode avoidance,
• Leverage data analysis results drive further optimization of the design and performance.
• Demonstrate effective use of appropriate industry and Cummins specific tools and software
• Consider system requirements and demonstrate a system thinking approach to work
• Demonstrate strong decision-making skills and a strong customer focus
• Collaborate and communicate effectively (both verbal and written) with key stakeholders and colleagues

U.S. Early Careers Eligibility Requirements:

Co-op (Co-operative): Students must be enrolled full-time at an accredited U.S. college or university, actively pursuing a degree (Bachelor’s, Master’s, PhD, MBA, or JD), with a minimum GPA of 2.5. Candidates must also currently reside within the continental United States. Students are expected to work 40 hours per week for assignments 4, 6, or up to 12 months, often aligning with school semesters. Some schools may require students to be officially enrolled in a co-op program—check with your career services or co-op office.

Academic Enrollment: If your co-op assignment is approved by your academic institution as part of a formal co-op program, the school acknowledges your participation and grants permission for you to take time off from classes while remaining in good academic standing. Cummins does not require you to be enrolled in a minimum number of credit hours during your co-op. Whether you take a semester off from classes, enroll part-time, or take evening courses is up to you and your school. You are responsible for meeting your university’s academic policies and/or co-op program requirements. Please consult your academic advisor or co-op office to ensure you remain in compliance.

International Student Eligibility (U.S. based roles): F-1 visa students must have approved Curricular Practical Training (CPT) or Occupational Practical Training (OPT) before their Early Career assignment begin. CPT/OPT must relate to their degree and be authorized by their university. Students are responsible for securing this approval through their school’s international office.

Commitment: Students must be able to manage their academic responsibilities without compromising their job performance.
