About the job

Requirements
  • A Bachelor's degree or higher in Materials Science, Chemical Engineering, Mechanical Engineering, or a related technical field.
  • 5-7+ years of hands-on experience in process engineering, material qualification, or manufacturing system development, preferably in R&D or high-mix/mid-volume environments.
  • Deep expertise in vacuum lamination, material stack alignment, and sheet-based manufacturing processes.
  • Experience qualifying new materials, especially polymers, for compatibility with advanced manufacturing processes.
  • A strong background in statistical methods, data visualization, systematic experiment design, and related software such as JMP and Minitab.
  • Ability to synthesize and interpret complex data sets to support material and process qualification.
  • Strong organizational skills and attention to detail.
  • Adaptability to changing requirements in a dynamic setting.
Responsibilities
  • Lead projects to qualify new materials for use in vacuum lamination, ensuring robust stack alignment and process compatibility.
  • Design, implement, and optimize testing pipelines that evaluate material behavior, stack integrity, and process performance under vacuum lamination conditions.
  • Collaborate with cross-functional teams to integrate new materials into existing and future manufacturing lines, focusing on seamless transition from R&D to production.
  • Develop and document best practices for material stack alignment and lamination parameters.
  • Analyze test data to assess material compatibility, identify process improvements, and support data-driven decision-making.
  • Work hands-on with high-volume manufacturing and R&D equipment, qualifying next-generation tools and processes for flexible circuit production.
  • Identify opportunities for automation and digitalization within material qualification and lamination processes.
  • Troubleshoot and resolve issues related to material handling, stack alignment, and vacuum lamination in a fast-paced environment.
Desired Qualifications
  • Experience in R&D or high-mix/mid-volume environments.

About the company

CelLink makes flex harnesses, flex circuits that replace traditional wiring in vehicles and industrial systems. They pack power, data, and sensing into a single thin circuit, with busing, fusing, and monitoring integrated, and use automated, tool-free manufacturing for quick design changes and high-volume production. Their approach reduces weight by over 70% and volume by over 90% compared with standard wiring and targets direct sales to OEMs and hyperscalers with scalable factories. Their goal is to speed electrification and the digitization of industrial infrastructure by providing compact, reliable power, data, and sensing networks for automotive, aerospace, data centers, and grid storage.

Simplify's Take

What believers are saying

  • DOE closed CelLink’s $362 million Georgetown loan in April 2024.
  • CelLink said July 2026 funding raised another $100 million at $989 million valuation.
  • March 2026 workforce data shows 175 employees and 34 active postings.

What critics are saying

  • Georgetown production timeline slipped from mid-2023 to 2025 openings, signaling execution strain.
  • A 175-person workforce cannot staff a 1,200-job factory without sustained hiring.
  • Failure to ramp Georgetown before DOE milestones jeopardizes financing and plant viability.

What makes CelLink Technologies unique

  • CelLink’s CCA+ folds bussing, sensing, and fusing into one flex circuit.
  • Its zero-tooling manufacturing enables design changes without new hardware.
  • October 2025 data-center flex circuits target megawatt racks and robotic assembly.
