Applies and supports the improvement of processes such as Pre Program Planning, (PPP), Product Preceding Technology, (PPT), Value Package Introduction (VPI), or Value Package Change, (VPC), Engineering Standard Work, (ESW), Functional Excellence Practice (FEP) and tools related to thermal and fluid sciences such as GT-Suite, Boost, Fluent, Converge, Concerto, CyberApps (virtual application model), Cummins Data Analysis Tool (CDAT), Mach, test data calculation, DARTS, test data storage, Calterm, Electronic Control Module (ECM) calibration tool, Emissions data system, Integrity, and ACCEPTS ECM in-loop test bench required to support the processes and enable high quality decision making. Obtains input and negotiates with immediate stakeholders, such as team members, technical managers, project leaders, other Thermal Sciences engineers, product and manufacturing engineers, and supplier partners and delivers information and recommendations to support project decisions, or to provide input related to further analysis, design optimization, feasibility studies, or architecture definition. Makes decisions in the areas of day to day project details, such as conducting analysis, testing, and communication with stakeholders that impact and support the successful progression of projects. Owns problem resolution for moderately complex components, products, systems, subsystems or services with technical complexity and ambiguity increasing as experience is gained in the role. Provides independent execution of established work processes and systems, while still developing technology or product knowledge; engages with the improvement of systems and processes. Involves minimal direct management of people, but could involve the coordination and direction of work amongst technicians and/or temporary student employees. Contributes effectively toward team goals, exhibits influence within a work group and continues to develop proficiency in the competency areas critical to success in the role. Competencies:
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.

Collaborates - Building partnerships and working collaboratively with others to meet shared objectives.

Communicates effectively - Developing and delivering multi-mode communications that convey a clear understanding of the unique needs of different audiences.

Decision quality - Making good and timely decisions that keep the organization moving forward.

Drives results - Consistently achieving results, even under tough circumstances.

Self-development - Actively seeking new ways to grow and be challenged using both formal and informal development channels.

Values differences - Recognizing the value that different perspectives and cultures bring to an organization.

Applies Principles of Statistical Methods - Analyzes technical data using descriptive statistics, probability distributions, graphical analysis, and statistical inference (population and sample, confidence intervals, and hypothesis testing); models relationships between response and independent variables using analysis of variance, regression, and design of experiments to make rigorous, data-based decisions.

Technical Documentation - Documents information based on knowledge gained as part of technical function activities; communicates to stakeholders with the goal of enabling improved technical productivity and effective knowledge transfer to others who were not originally part of the initial learning.

Product Development Execution, Monitoring and Control - Plans, schedules, coordinates and executes the activities involved in developing a product to a respectively aligned hierarchy of requirements and technical profiles; monitors and communicates across functional boundaries to meet project resource and quality expectations; ensures product capability meets or exceeds expectations and takes mitigating actions when project risks are higher than expected; understands the full product life cycle process and stakeholders.

Design and Application of Open/Closed Loop Controls - Specifies software features that interact with mechanical, hydraulic, chemical and electronic systems to deliver desired system states; specifies control system architectures which include appropriate measurements, correct actuation, and algorithms for Cummins' products; configures and/or understands open/closed loop feedback controls features and the system interactions between hardware and software in Cummins' products.
