Job summary

CelLink Corporation is seeking a Tech Transfer Process Engineer to bridge pilot production to high-volume manufacturing across EV, energy storage, and data center applications. You will characterize and mature processes, validate equipment, and develop readiness plans to ensure rapid, reliable scale-up.

You will work hands-on on the production floor, leading process qualification, troubleshooting, and training to sustain robust manufacturing.

Qualifications

• Bachelor’s degree in a relevant field.
• 3+ years of hands-on professional experience.
• Proven experience transitioning processes from pilot production into high-volume production.
• Strong background in process design for manufacturability, yield improvement, and cost reduction.
• Experience with production launches, process transfers, and manufacturing scale-up activities.
• Prior manufacturing start-up experience.
• Familiarity with advanced materials and high-volume manufacturing methods (e.g., vacuum lamination, thermally-activated adhesives, roll-to-roll processing, material patterning, laser welding).
• Solid background in statistical methods and data visualization (e.g., JMP, Minitab).
• Ability to troubleshoot and operate custom manufacturing/metrology equipment.
• Strong communication and collaborative skills across functions.

Responsibilities

• Own the transfer of products from NPI into high-volume manufacturing, including travel to the high-volume site (Georgetown, TX).
• Scale and mature manufacturing processes from NPI builds to repeatable, high-volume production.
• Establish and validate process windows, operating parameters, and control strategies for production targets.
• Lead process qualification, capability studies, and validation activities.
• Partner with customer-facing teams and cross-functional engineering groups to drive launch readiness.
• Provide hands-on, on-site launch ownership and line support during ramp.
• Conduct structured experiments and root cause analysis to de-risk scale-up.
• Work hands-on with high-volume manufacturing equipment.
• Develop and maintain manufacturing documentation and train staff for smooth handoff to sustained production.

Job description

Tech Transfer Process Engineer

As a Process Engineer on our Tech Transfer team, you will play a critical role in bridging the gap between New Product Introduction (NPI) and High Volume Manufacturing (HVM). Your mission is to transform pilot manufacturing processes into robust, repeatable, and scalable production solutions that can be successfully launched and sustained in volume production.

You will be hands-on throughout the transfer process: characterizing and maturing processes, developing manufacturing readiness plans, validating equipment and process capability, troubleshooting production challenges, and establishing the documentation and training required for a successful launch. You’ll partner closely with NPI, Design, Operations, Quality, Equipment, and Controls teams to ensure products transition smoothly from launch into stable, capable manufacturing processes that consistently achieve yield, cycle time, and quality targets while minimizing risk during production ramp.

This is a highly cross-functional role for an engineer who enjoys solving complex manufacturing problems, working directly on the production floor, and turning innovative technologies into reliable, scalable manufacturing processes that enable the future of power and data transmission across EV, energy storage, data centers, and aerospace applications.

Essential Duties and Responsibilities

To perform this job successfully, the individual must be able to perform each essential duty satisfactorily.

• Own the transfer of products from NPI into high-volume manufacturing, including 25-50% travel to the high volume manufacturing site (Georgetown, TX)
• Scale and mature manufacturing processes from NPI builds to repeatable, high-volume production, with a focus on yield, throughput, cycle time, quality, and manufacturability
• Establish and validate process windows, operating parameters, and control strategies required to achieve production targets.
• Lead process qualification, capability studies, and structured validation activities to demonstrate that processes can consistently meet production requirements.
• Partner with customer-facing teams and cross-functional engineering groups to resolve technical gaps and drive launch readiness
• Provide hands-on, on-site launch ownership and line support during high-volume ramp, including troubleshooting, debugging, and rapid resolution of process issues.
• Conduct structured experiments and root cause analysis to de-risk manufacturing scale-up and accelerate product launches
• Work hands-on with high-volume manufacturing equipment
• Develop and maintain manufacturing documentation and train staff to ensure smooth handoff from Tech Transfer into sustained high-volume production
