Job description

Process Engineer – New Product Introduction (NPI) As a Process Engineer on our New Product Introduction (NPI) team, you’ll be at the forefront of transforming advanced manufacturing concepts into real-world products and solutions. Your role will be to design and scale processes that bridge the gap between prototype and production, ensuring high-volume manufacturability, validating first articles, and enabling the successful launch of products across EV, energy storage, and aerospace industries. This is more than engineering; it’s turning bold ideas into manufacturable realities that accelerate the future of power and data transmission. These openings are for Level 4-5 engineers Essential Duties and Responsibilities Scale innovative processes from prototype to high-volume manufacturing, driving 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 out product viability and readiness for commercialization Identify product development needs and act as a conduit for aligning 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 R&D equipment Develop process documentation and train staff to ensure smooth handoff from NPI into sustained high-volume production Minimum Qualifications (Knowledge, Skills, and Abilities) Experience/Education Bachelor's degree or higher in Materials Science, Physics, Chemical Engineering, Chemistry, or related field. 5-7+ years of hands-on professional experience Knowledge/Skills/Abilities Proven experience scaling processes from prototype to production. 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 (e.g., vacuum lamination, thermally-activated adhesives, roll-to-roll processing, material patterning, laser welding) Solid background in statistical methods, data visualization, systematic experiment design, and related software (e.g. JMP, Minitab, etc.) 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. Independent problem solver with a desire to learn new skills and new technology. Strong organization skills and a detail-oriented mindset. Able to adapt to changing requirements in a fast-paced start-up setting. Strong communicator and collaborator, energized by working across functions to bring products to market. At CelLink, you won’t just be scaling processes - you’ll be building the bridge between innovation and mass production.
