Original job description

Founded with the vision to electrify everything, Group14 is the leading commercial manufacturer of advanced silicon battery materials. Our breakthrough technology, SCC55®, is a drop-in ready replacement for graphite that seamlessly integrates into existing lithium-ion manufacturing to unlock transformational energy density and faster charging. By delivering high-performance materials at commercial scale, we are strengthening global battery supply chain security and enabling the next generation of rechargeable batteries for global automotive OEMs, cell manufacturers, AI-enabled consumer electronics, grid-scale energy storage, and other innovative industrial segments.

Over the past year, Group14 reached major milestones that underscore our momentum. We closed a $665 million Series D round bringing our total equity raised to well over $1 billion. We have a truly global footprint, with locations in Asia, the US and Europe, supporting resilient, localized supply chains and scaling production to meet surging worldwide demand. Headquartered in Washington state, Group14 is backed by world-class investors and customers, including Porsche, ATL, Microsoft, and SK Inc. As we continue to grow, we are building a team united by passion for shaping the future of energy.

The Cell Engineer will play a pivotal role in supporting the commercialization of SCC55Ⓡ, Group14’s best-in-class silicon anode material. You will be responsible for designing, developing, and assembling silicon battery pouch cells for high-energy and high-power applications on our laboratory-scale production line. These cells will directly showcase the revolutionary capabilities of SCC55Ⓡ and drive customer adoption. Additionally, this role will spearhead the technology transfer of SCC55Ⓡ into commercial cell designs and prototype engineering solutions for the continuous improvement of our battery cell line.

WHAT YOU’LL BE DOING:

Develop and establish cell design details required for high-energy and high-power applications.
Design and execute protocols to optimize various processes in cell development, production, and testing - from concept through implementation.
Testing the electrochemical performance profile and physical characteristics of silicon batteries.
Conduct root-cause investigations, prepare detailed status reports on problems or issues, and make actionable recommendations as required.

WHAT WE'RE LOOKING FOR:

B.S. in Chemical Engineering, Electrochemical Engineering, Material Science, or a related field.
3+ years of experience working at a lithium-ion battery manufacturer or within a battery-focused research lab.
Proven experience maintaining and operating pouch cell assembly equipment at the laboratory or pilot scale.
Expertise using advanced cell testing systems and methods to characterize battery performance.
Knowledge of lithium-ion battery safety practices and the physical ability to wear a respirator.
Strong written and verbal communication skills in English.
A self-motivated mindset with the ability to thrive as an independent contributor.

OTHER QUALITIES WE'D LOVE YOU TO HAVE:

1+ years of dedicated experience making multilayer pouch cells.
In-depth knowledge of how mixing, coating, and calendaring directly impact cell performance.
Strong background in cell design, formulation, and end-to-end cell development.
Deep understanding of cell degradation mechanisms and failure mode analysis.
Experience operating a pouch cell manufacturing line.
Hands-on proficiency with precision metrology tools, including calipers, micrometers, and laser distance sensors.
Experience designing and building custom fixtures and test leads.
Proficiency in AutoCAD or 3D modeling software.

Base Pay Range

$95,000 - $120,000 USD
