Job description

Lyten is leading an industrial revolution through Lyten 3D Graphene™, a breakthrough supermaterial unlocking a new generation of products — from lithium–sulfur batteries and energy storage systems to concrete admixtures, lightweight composites, and next‑generation sensors that are revolutionizing industries. Together, these innovations are making a massive global improvement and driving real‑world impact across energy, mobility, construction, and defense. At Lyten, we believe the most meaningful careers begin with purpose — and with people who want to make a difference. We’re not just developing advanced supermaterials — we’re about to change the world as we know it, reshaping how energy is stored, how products are built, and how progress is made. We’re entering an exciting growth phase, scaling production across the U.S. and Europe and expanding our team of engineers, scientists, and innovators.

Lyten is seeking a Manufacturing Engineer with a strong desire to contribute and grow in a demanding environment. This position is responsible for designing, implementing, controlling, and optimizing industrial processes and equipment, specifically related to pouch cell assembly. The Engineer will develop and execute experimental programs and operations plans to meet production targets.

Job Responsibilities:

• Process Ownership & Maturation: Develop, document, and stabilize assembly processes specifically for pouch cell manufacturing, taking ownership of a shifting and evolving pilot line environment.
• Sustaining & Optimization: Actively monitor equipment performance, analyze process workflows, and introduce continuous improvements to increase yield and throughput on the existing line.
• Data-Driven Troubleshooting: Create, plan, and execute Design of Experiments (DOEs) to understand the assembly processing window. Utilize production data to systematically troubleshoot and resolve complex process and equipment issues.
• Adaptability to the Unknown: Comfortable operating in “grey areas” where documentation or processes might be incomplete; proactively drive clarity and establish control where it doesn’t yet exist.
• Cross-Functional Alignment: Collaborate with R&D, sourcing, and production teams to align day‑to‑day pilot line operations with development schedules and cell integration targets. Help develop junior engineers in engineering methods.
• Documentation: Develop and iterate detailed Standard Operating Procedures (SOPs), control plans, and specification requirements as the pouch cell assembly process matures.
• Vendor Support (As Needed): Interface with equipment suppliers as required to resolve deep technical issues.
• Reporting & Justification: Provide regular updates to engineering leadership regarding equipment states. Use data and experimental results to justify and recommend modifications or upgrades.
• Safety & Compliance: Conduct equipment risk assessments (e.g., FMEAs) and strictly adhere to safety regulations and internal company policies.

Required Qualifications:

• BS in Mechanical Engineering or equivalent.
• Typically, 5+ years of hands‑on engineering experience in a manufacturing, pilot, or scale‑up environment.
• Minimum of 2 years working with battery cell stacking, notching, and/or assembly equipment.
• Proficient in CAD design, GD&T and tolerance stack up analysis.
• Demonstrable track record of solving complex process engineering issues.
• A strong desire to learn, high adaptability to a fast‑paced “pilot line” environment, and a comfortable attitude toward working with evolving, less‑mature systems.
• Solid understanding of engineering fundamentals, statistical concepts, and proficiency with data tools (Excel, MATLAB, JMP, Minitab, etc.).
• Strong verbal and written communication skills; ability to clearly document processes and present findings to the team.
• Expected to travel <10%.
