Process Engineer Mixing & Coating – Battery Cell Development Center

Job Description

The Role

At General Motors were driving the future of mobility through cutting-edge battery cell innovation. As a Process Engineer for electrode Mixing & Coating youll play a critical role in developing and refining cell technologies that power our electric future. This is a hands-on on-site position at the Battery Cell Development Center where youll collaborate with top-tier engineers and researchers to push the boundaries of cell technology.

Were looking for a candidate who is passionate about advancing technologies in battery cells and eager to continuously learn and grow. You will engage directly in a development manufacturing setting collaborating closely with process operations maintenance quality and product engineering teams to develop and stabilize scalable manufacturing processes for battery cells.

What Youll Do

• Process Development Mixing & Slurry Preparation You will help develop the process parameters operating windows and work instructions for slurry mixing (cathode and/or anode). Optimize mixing sequences order of addition shear rates temperature and vacuum/deaeration conditions. Characterize slurry rheology and stability to establish acceptance criteria and checks. Partner with product engineers and suppliers to qualify new active materials binders solvents and conductive additives.
• Process Development Coating & Drying You will help develop process parameters for rolltoroll coating (e.g. slotdie comma bar) and drying for battery cell electrodes. Tune key settings (web speed gap pump settings tension oven zones air flows) to meet coating thickness uniformity and defect targets. Develop and maintain procedures for setup startup changeovers and shutdown to ensure safe stable operation. Interface with calendaring and downstream steps to ensure coating output supports density porosity and cell performance targets.
• ScaleUp Trials & Continuous Improvement - Plan and execute DOEs and structured experiments to expand process windows and improve yield scrap and throughput. Partner with quality to analyze process and quality data and identify root causes of defects (e.g. streaks agglomerates edge defects pinholes delamination) and implement robust corrective actions. Support equipment commissioning debug and SAT/FAT for new mixing and coating assets or upgrades. Capture lessons learned and standardized best practices for reuse across campaigns and future lines.
• Documentation You will help to develop and maintain standard work SOPs control plans and reaction plans for mixing and coating operations. Work with quality to define CTQs/CTPs sampling plans and acceptance criteria for slurry coated web and inprocess checkpoints. Maintain clear documentation of trials parameter changes risk assessments and process changes. Ensure compliance with GM safety standards EHS requirements and leanroom/solventhandling procedures.
• CrossFunctional Collaboration - Work closely with operations/technicians to train and coach process intent setup troubleshooting and best practices. Partner with maintenance and controls/automation team members to improve uptime diagnostics and errorproofing. Collaborate with cell design formation and test teams to link electrode process conditions to cell performance and durability. Communicate technical learnings and recommendations clearly to both technical and nontechnical stakeholders.

Your Skills & Abilities (Required Qualifications)

• Bachelors degree in chemical engineering Materials Science Mechanical Engineering or related engineering field.

• 3 years of experience in process engineering manufacturing engineering or similar role in:

  • Liion battery manufacturing or

  • Coating inks films or related webbased processes or

  • Other wetchemistry / mixingintensive manufacturing.

• Handson experience with mixing processes (slurry inks coatings or adhesives) and basic rheology concepts.

• Handson experience with coating or web handling processes (slotdie comma bar gravure or similar).

• Demonstrated ability to design and run DOEs analyze data and solve complex process problems with a structured approach.

• Strong communication skills and ability to work crossfunctionally with operations maintenance quality and suppliers.

• Willingness to work in an onsite pilot manufacturing environment with time spent on the production floor.

What Will Give You A Competitive Edge (Preferred Qualifications)

• Direct experience in Liion electrode manufacturing (slurry mixing coating drying calendaring).

• Experience with rolltoroll coating equipment and web handling (tension control edge guiding defect detection).

• Familiarity with battery materials (cathode/anode active materials binders solvents conductive additives) and their impact on processability and performance.

• Experience in a development or rampup environment (frequent changeovers trials and nonsteadystate operation).

• Working knowledge of SPC DOE and basic statistics applied to manufacturing processes.

• Experience using manufacturing data systems (historian MES quality databases) for troubleshooting and continuous improvement.

• Demonstrated commitment to safety including solvent handling powder handling and cleanroom or dryroom operations.

Additional Information

• This role is categorized as onsite. This means the successful candidate is expected to report to Battery Cell Development Center (BCDC) in Warren Michigan on a full-time basis

• This role may require occasional offshift or weekend support during critical trials debug or rampup phases.

• Domestic and/or international travel may be required to visit equipment or materials suppliers or partner sites as needed.
