Qualifications:

• Bachelor’s degree in Materials Science, Chemical Engineering, Mechanical Engineering or related field (Master’s preferred)
• Proven 5+ years of experience in Li-ion or next-generation battery cell development, with proven contributions in electrode and cell design.
• Strong knowledge of electrochemistry, cell engineering principles, and component interactions.
• Hands-on experience with lab-scale electrode preparation, slurry formulation, coating, and coin/pouch/prismatic cell builds.
• Prior experience with CAD tools and cell design modeling software.
• Excellent problem-solving, data analysis, and communication skills.
• Ability to thrive in a fast-paced startup or innovation-driven environment.

Preferred Skills:

• Experience with lithium metal, solid-state, or high-voltage cathode systems.
• Background in scaling up laboratory innovations to pilot production environments.
• Knowledge of safety standards and regulatory requirements for energy storage devices.
• Experience collaborating with contract manufacturers or equipment vendors.

Benefits:

• Fully covered health and dental insurance
• Generous vacation time
