About the job

Requirements
  • A bachelor's degree or higher in Materials Science, Physics, Chemical Engineering, Chemistry, or a related field.
  • Five to seven or more years of hands-on professional experience.
  • Proven experience scaling processes from prototype to production.
  • A strong background in process design for manufacturability, yield improvement, and cost reduction.
  • Experience with prototype builds, first article validation, and technical collaboration.
  • Prior manufacturing start-up experience.
  • Familiarity with advanced materials and high-volume manufacturing methods, including vacuum lamination, thermally activated adhesives, roll-to-roll processing, material patterning, and laser welding.
  • A solid 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 understand physical phenomena and support data-driven decisions.
  • Ability to safely and confidently operate and troubleshoot custom manufacturing and metrology equipment.
  • Strong organization skills and a detail-oriented mindset.
  • Ability to adapt to changing requirements in a fast-paced start-up setting.
  • Ability to lift and/or move up to 50 pounds without assistance.
  • Ability to wear required personal protective equipment and adhere to prescribed safety procedures.
Responsibilities
  • Scale innovative processes from prototype to high-volume manufacturing to drive yield, throughput, and manufacturability.
  • Design, implement, and validate manufacturing processes that ensure product scalability, quality, and reliability.
  • Build and qualify first articles while establishing process readiness for customer and internal validation.
  • Partner with customer-facing teams and cross-functional engineering groups to prove product viability and readiness for commercialization.
  • Identify product development needs and align process roadmaps with customer requirements and future technologies.
  • Conduct structured experiments and root cause analysis to de-risk manufacturing scale-up and accelerate product launches.
  • Work hands-on with high-volume manufacturing and research and development equipment.
  • Develop process documentation and train staff to ensure a smooth handoff from new product introduction into sustained high-volume production.

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.
