Strong problem-solving skills, attention to detail, and effective collaboration are standout soft skills for this technical role. These skills and qualities are crucial for innovating, diagnosing issues, and advancing battery technologies in a rapidly evolving field.

What does a Battery Cell Materials Engineer do?

A Battery Cell Materials Engineer specializes in developing and optimizing the materials used in battery cells, such as electrodes, electrolytes, and separators. Their work involves researching new materials, improving existing ones, and ensuring the safety, efficiency, and longevity of batteries. They often collaborate with scientists, manufacturers, and product designers to create batteries for applications like electric vehicles, consumer electronics, and renewable energy storage. Their expertise helps advance battery technology to meet industry demands for higher performance and sustainability.

What are some common challenges faced by Battery Cell Materials Engineers when developing new battery chemistries?

Battery Cell Materials Engineers often encounter challenges such as ensuring material compatibility, optimizing energy density, and maintaining safety standards. Developing new chemistries requires rigorous testing to balance performance, lifespan, and cost while addressing issues like degradation or instability under various conditions. Collaboration with cross-functional teams—including chemists, manufacturing specialists, and quality control engineers—is essential to troubleshoot problems and scale up successful prototypes for mass production.

What is the difference between Battery Cell Materials Engineer vs Battery Pack Design Engineer?

AspectBattery Cell Materials EngineerBattery Pack Design Engineer
Primary FocusDeveloping and optimizing materials for battery cellsDesigning and assembling battery packs for performance and safety
Required SkillsMaterials science, electrochemistry, laboratory testingMechanical design, electrical systems, thermal management
Work EnvironmentResearch labs, material testing facilitiesEngineering offices, vehicle assembly lines
Industry UsageBattery manufacturing, R&DElectric vehicle manufacturing, energy storage systems

The Battery Cell Materials Engineer focuses on developing the materials that make up individual battery cells, while the Battery Pack Design Engineer concentrates on designing the overall battery packs used in devices or vehicles. Both roles are essential in the battery industry but differ in their specific responsibilities and skill sets.

Position Summary:
We are seeking a highly skilled Battery Pack Engineer to support the design, assembly, testing, and production optimization of advanced battery packs. The ideal candidate will have hands-on experience in battery pack assembly, be familiar with Arbin battery cyclers for performance testing, and have expertise in Amada and Hesse welding machines for precision welding of battery interconnections and busbars. This role involves working closely with production teams, quality engineers, and R&D to ensure high reliability and performance of battery systems.

Key Responsibilities:

  • Design & Development:
    • Support the development and optimization of battery pack designs, layouts, and electrical schematics.
    • Define process parameters for welding, joining, and bonding operations for battery modules.
    • Collaborate with R&D on cell selection, pack configuration, and system integration.
  • Production Support:
    • Oversee battery pack assembly processes, ensuring adherence to quality standards and production schedules.
    • Operate and maintain Amada and Hesse welding machines for busbar and tab welding, ensuring proper weld quality and consistency.
    • Define and maintain SOPs, process documentation, and assembly work instructions.
  • Testing & Validation:
    • Perform battery cell and pack testing using Arbin cyclers, including charge/discharge cycling, capacity verification, and performance characterization.
    • Support failure analysis, root cause investigations, and corrective actions for battery performance issues.
    • Assist in battery safety, environmental, and reliability testing as per industry standards.
  • Quality & Safety:
    • Ensure compliance with ISO, IATF, and other relevant quality management standards.
    • Implement quality control measures for welding joints, electrical connections, and thermal management components.
    • Enforce ESD and high-voltage safety protocols during production and testing activities.
  • Continuous Improvement:
    • Identify opportunities for process automation, efficiency improvement, and cost reduction.
    • Provide feedback to equipment and process engineering teams for ongoing optimization.

Qualifications & Skills:

  • Education: Bachelor's degree in Mechanical Engineering, Electrical Engineering, Materials Science, or a related field.
  • Experience:
    • 2+ years of hands-on experience in battery pack design, assembly, or testing.
    • Direct experience with Arbin battery test equipment and Amada welding systems (laser or resistance welding).
    • Strong understanding of lithium-ion battery technology, cell balancing, and BMS integration.
  • Technical Skills:
    • Proficiency in interpreting electrical schematics, CAD drawings, and mechanical assembly diagrams.
    • Knowledge of welding parameters (current, pressure, pulse) and weld inspection criteria.
    • Familiarity with data acquisition, test data analysis, and failure mode analysis (FMEA).
  • Soft Skills:
    • Strong problem-solving and troubleshooting skills.
    • Ability to work collaboratively in a cross-functional production environment.
    • Excellent documentation, communication, and reporting skills.
