This is an exciting opportunity in Columbus, IN for a Senior technical specialist – Battery modeling & controls. Cummins USA is where you can work on industry leading engineering projects such as New Product Development, Value Package Introduction and Systems Product Validation.

Your impact will happen in these and other ways:

  • This applied science position applies chemical principles that create and develop product functionalities which are integrated and sold into Cummins’ products. The position involves the research, design, analysis, testing and failure analysis of chemical based products, including catalyst, substrates, sensors, batteries and fuel cells.

  • Provides independent leadership of smaller business impact projects or ownership of complex components, products, systems or services with greater elements of ambiguity over the senior or lead engineer level and with full accountability to the project team.

  • Delivers independent execution of established and emerging work processes and systems, while still developing technology or product knowledge.

  • Leads the development and improvement of work processes and systems across a functional discipline area within a business unit.

  • Coordinates and directs work amongst technicians and temporary student employees, assists in the transfer of knowledge to lesser experienced engineers through either indirect (scope of influence) or direct management of a small, local group of engineers.

  • Provides support and guidance to influence technical direction within a project team and continues to develop proficiency in the competency areas critical to success in the role (see “competencies” below).

  • Operates as a recognized specialist in a discipline or product area within the immediate team.


Chemical or Electrochemical Performance Testing - Designs tests measuring chemical transformation of species, selectivity, electric yield, response to chemical and physical environments in order to determine performance, durability, or state of health of chemically or electrochemically active components; examines and interprets test data using analysis methods to draw conclusions that influence hardware and controls design decisions and to provide information for computational tools development.

Characterization of Chemical Systems - Designs and conducts tests of physicochemical properties, for example morphology, acid-base and redox properties, diffusion characteristics, impedance behaviors, solubility, and chemical poisoning, in order to aid in diagnostics and prediction of performance and health of chemically active components.

Accelerated Aging Testing and Analysis - Designs and constructs laboratory equipment to simulate various aging exposures relevant to practical applications of active chemical components, including thermal cycling, chemical poisoning, and physical masking.

Simulation of Chemical Systems - Determines chemical or electrochemical performance of chemically active components and systems via numerical modeling; estimates conversion, selectivity, electrical yield, resistance, and state of health via numerical computations to evaluate and guide hardware and controls design decisions.

System Capability Engineering - Identifies system capability and risks through analysis or experimental testing of the system, sub-system, or super system in the context of its environment; negotiates and verifies requirements against capability to guide project scope and system development accordingly; assesses legacy system versus proposed new system solution capabilities and makes decisions as to how best to achieve system capability with consideration of stakeholder trade-offs.

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.

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

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

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

Builds networks - Effectively building formal and informal relationship networks inside and outside the organization.

Resourcefulness - Securing and deploying resources effectively and efficiently.

Manages complexity - Making sense of complex, high quantity, and sometimes contradictory information to effectively solve problems.

Education, Licenses, Certifications

Bachelor's degree in Engineering or other relevant technical disciplines is required. Post-graduate (Master's) degree relevant to this discipline area may be required for select roles.


  • 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

  • In this position, the candidate will support the development of a variety of battery control strategies and methods that ensure optimal and safe battery operation. This includes control-oriented battery modeling, state estimation, calibration and validation at all levels (cell to pack).

  • The ideal candidate for this role will design algorithms to estimate and optimize battery performance, and to prolong battery life by actively addressing cell degradation. Additionally, the person in this role will interface with various engineering groups to define key Battery Management System (BMS) requirements & guidelines for system level validation.

Key Responsibilities

  • Develop control-oriented battery models (electrical and/or electrochemical, thermal)

  • Design battery state of charge/health/power, temperature, and fault estimation algorithms

  • Design experiments at the cell/module/pack levels to characterize and validate developed control oriented models & algorithms

  • Work with software engineering and firmware engineering teams to define requirements for battery management system software

  • Collaborate with the electrochemistry team to understand battery behavior and design necessary test plans for battery management system development

  • Interface with thermal modeling group to understand thermal system behavior and limitations for battery management system development

  • Support to establish hardware in the loop (HIL) capabilities for BMS development and testing

Basic Qualifications:

M.S. in engineering with a minimum 3 years of experience or Ph.D. in engineering with a good publication record in battery modeling and controls

  • Deep understanding of battery modeling, estimation, and control methods

  • Experience with control-oriented battery models (e.g. equivalent circuit models, reduced order electrochemical models, and thermal models) for estimation and control

  • Model-based estimation and control algorithms (e.g., Kalman filters, Particle filter) development, implementation, calibration, code optimization, and experimental validation experience

  • Expertise in MATLAB/Simulink

  • Experience in functional safety and AUTOSAR is a plus

  • Good understanding of battery behavior from beginning of life through end of life

  • Good understanding of mechanical, electrical, electrochemical, and thermal systems

  • Excellent communication skills and team-working spirits

  • Self-starter and able to multi-task in fast paced environment

Compensation and Benefits

Base salary rate commensurate with experience.
