Thermal and Fluid Systems Technical Specialist

We are looking for a talented Thermal and Fluid Systems Technical Specialist to join our team specializing in Engineering for our Corporate organization in Columbus, IN .

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

• Drive informed, high-quality project decisions by negotiating with cross-functional stakeholders and translating complex technical data into actionable guidance.
• Own and execute higher-impact project decisions through hands-on analysis, testing, and stakeholder communication that accelerate project progression.
• Apply and continuously improve core engineering and product development processes (PPP, PPT, VPI/VPC, ESW, FEP) to strengthen quality and execution rigor.
• Leverage advanced thermal, fluid, and data analysis tools to support feasibility studies, design optimization, and architecture definition.
• Lead smaller business-impact projects or take full ownership of complex systems or components, navigating ambiguity with accountability and confidence.
• Independently execute established and emerging work processes while expanding technical depth and product knowledge in evolving technologies.
• Coordinate and direct work across technicians, co-ops, and early-career engineers, accelerating capability through knowledge transfer and coaching.
• Serve as a recognized technical specialist within the team, influencing technical direction and contributing to continuous functional excellence.

• Applies Principles of Fluid Dynamics and Heat Transfer - Interprets and predicts the performance of fluid and thermal systems by leveraging a quantitative and intuitive comprehension of the flow of liquids and gases, the transfer of thermal energy between elements of a system, and the application of modeling and experimental tools, to answer key questions about the system or component.
• Applies Principles of Thermodynamics and Energy Conversion Systems - Interprets and predicts the performance of energy conversion systems such as IC engines, gas turbines, fuel cells, and batteries, by leveraging a quantitative and intuitive comprehension of thermodynamics, fluid mechanics, modeling tools, controls, and experimental tools to answer key questions about the system or component.
• Product Failure Mode Avoidance - Mitigates potential product failure modes, by identifying interfaces, functions, functional requirements, interactions, control factors, noise factors, and prioritized potential failure modes and potential failure causes for the system of interest to effectively and efficiently improve the reliability of Cummins' products.
• Product Function Modeling, Simulation and Analysis - Impacts product design decisions through the utilization and/or interpretation of computational tools and methods that predict the capability of a product's function relative to its system, sub-system and/or component level requirements.
• Product Problem Solving - Solves product problems using a process that protects the customer; determines the assignable cause; implements robust, data-based solutions; and identifies the systemic root causes and recommended actions to prevent problem reoccurrence.
• System Requirements Engineering - Uses appropriate methods and tools to translate stakeholder needs into verifiable requirements to which designs are developed; establishes acceptance criteria for the system of interest through analysis, allocation and negotiation; tracks the status of requirements throughout the system lifecycle; assesses the impact of changes to system requirements on project scope, schedule, and resources; creates and maintains information linkages to related artifacts.
• Systems Thinking - Defines the system of interest by drawing the boundaries, identifying its context within its environment, its interfaces, and that it has a lifecycle to aid in planning the problem statement, scope and deliverables ; analyzes linkages and interactions between elements that comprise the system of interest by using appropriate methods, models and integration of outcomes to understand the system, predict its behavior and devise modifications to it in order to produce the desired effects.

• College, university, or equivalent Bachelor's degree in Engineering or appropriate STEM field is required.
• Post-graduate (Master's) degree relevant to this discipline area may be required for select roles.
• This position may require licensing for compliance with export controls or sanctions regulations.

• Prior Senior or Lead Engineer equivalent work experience in a relevant discipline area is required with a demonstrated track record of technical problem solving and quality decision making.
• Knowledge of MS Office tools is preferred.

• Knowledge of Internal Combustion Engines is required.
• Familiarity with OBD ETM diagnostics is preferred.
• Enable data-driven decision-making by delivering actionable insights and guidance to test engineers.
• Analyze repeat point data across all OBD test cells and provide actionable feedback to test engineers.
• Analyze FTP and RMCSET cycle data collected during the OBD diagnostic tests to confirm cycles ran as expected.
• Ability to assess the impact of various induced failure conditions on engine performance and verify that test cycles are executed as expected.
• Utilize OBD plotting tools to assess and ensure data quality.
• Collaborate with test engineers to review data and verify that all required checks are completed prior to stakeholder communication.
• Validate data collected for each test plan to ensure accuracy and completeness.
• Lead training initiatives to upskill engineers in data analysis and review.
