Battery Process Engineer information

What does a Battery Process Engineer do?

A Battery Process Engineer is responsible for designing, optimizing, and overseeing the manufacturing processes involved in producing batteries, such as lithium-ion cells. They work to improve efficiency, quality, and safety in battery production by developing and refining procedures, selecting appropriate materials, and troubleshooting issues. Additionally, they collaborate with teams across research, development, and manufacturing to scale up new battery technologies from prototype to mass production. Their role is critical for ensuring that batteries meet performance and reliability standards required for various applications, including electric vehicles and consumer electronics.

What is the difference between Battery Process Engineer vs Battery Manufacturing Technician?

AspectBattery Process EngineerBattery Manufacturing Technician
CredentialsBachelor's degree in engineering or related field; often requires experience in process designHigh school diploma or technical certification; on-the-job training
Work EnvironmentDesigning, optimizing, and overseeing manufacturing processes in labs or production facilitiesOperating machinery and performing manual tasks on the production line
Industry UsageInvolved in process development, quality control, and process improvementFocuses on assembly, equipment operation, and quality checks

The Battery Process Engineer focuses on designing and improving manufacturing processes, requiring technical expertise and engineering credentials. In contrast, the Battery Manufacturing Technician handles day-to-day production tasks, operating equipment and ensuring product quality. Both roles are essential in battery manufacturing but differ in responsibilities, skills, and work scope.

What are some common challenges faced by Battery Process Engineers during scale-up from laboratory to production?

Battery Process Engineers often encounter challenges when translating lab-scale processes to full-scale manufacturing, such as maintaining quality and consistency in large batches, optimizing equipment for high throughput, and ensuring safety protocols with reactive materials. These professionals must troubleshoot unexpected variations, coordinate closely with multidisciplinary teams (like R&D, quality assurance, and maintenance), and refine processes to meet both performance and cost goals. Effective communication and problem-solving skills are essential for overcoming these hurdles and ensuring smooth production ramp-up.

What are the key skills and qualifications needed to thrive as a Battery Process Engineer, and why are they important?

To thrive as a Battery Process Engineer, you need a solid background in chemical or materials engineering, experience with battery manufacturing processes, and often a relevant engineering degree. Familiarity with process simulation software (such as AutoCAD or MATLAB), Six Sigma methodologies, and data analysis tools is typically required. Strong problem-solving abilities, attention to detail, and effective communication skills help distinguish top performers in this field. These competencies are essential to ensure efficient battery production, maintain high quality standards, and drive innovation in the rapidly evolving energy storage industry.

Job description

Coreshell's metallurgical Silicon anode technology delivers high capacity, fast-charging, and superior safety. Our low-cost Silicon-dominant batteries have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Coreshell's Si anode material is lower than the cost of graphite and utilizes the largest abundant critical mineral supply in the US and Europe. We strive to transform the global energy and transportation market by enabling cost effective and secure domestic battery supply.
Core Responsibilities: We are seeking a Junior Process Engineer to join our battery process technology team. This role supports the development, optimization, and stabilization of electrode, cell assembly, and formation processes. The ideal candidate is highly motivated, detail-oriented, and eager to grow into a process expert in next-generation battery technologies .
Responsibilities include:
  • Process monitoring: Monitor daily production KPIs (yield, scrap, downtime) and identify abnormalities.
  • Data analysis: Analyze process and quality data to support root cause investigations.
  • DOE execution: Assist in planning and running Design of Experiments to optimize process parameters.
  • Equipment support: Work with equipment engineers to troubleshoot process issues.
  • SOP documentation: Create and update standard operating procedures and work instructions.
  • Quality collaboration: Support quality teams in defect analysis and corrective actions.
  • Sample preparation: Prepare samples for lab testing (adhesion, resistance, thickness, etc.).
  • Cross functional communication: Collaborate with R&D, Quality, and Production teams to implement improvements.

Preferred Technical Areas:
  • Electrode process: mixing, coating, calendering, slitting
  • Cell assembly: stacking/Z-folding, welding, electrolyte filling, formation
  • Quality systems: SPC, MSA, FMEA
  • Data tools: Python, JMP, Minitab, Tableau (plus)

Qualifications:
  • Bachelor's degree in Chemistry, Chemical Engineering, Materials Science, Mechanical Engineering, Industrial Engineering, or related field
  • 0-2 years of experience in battery cell manufacturing (process development, process technology or manufacturing environment preferred)
  • Strong analytical and problem-solving skills
  • Ability to work in fast-paced production environments
  • Basic understanding of statistical analysis
  • Good communication and teamwork skills

Preferred Qualifications:
  • Internship or project experience in battery manufacturing
  • Experience with DOE, SPC, or Six Sigma tools
  • Familiarity with lithium-ion cell structure and production flow
  • Hands-on experience with lab measurement tools (viscometer, caliper, UTM, etc.)

Location & Benefits: San Leandro, CA. Full-time. $72,000-85,000. Salary and equity options dependent on experience. Dental, vision, healthcare and 401(k) benefits are included. Applications will be screened as received.
