Engineering Intern – Materials & Process Modeling (Summer 2026)

CelLink Corporation • San Carlos, CA

12h • $25 - $35 • Onsite

About The Position

CelLink is seeking a highly motivated Engineering Intern to support a focused, high-impact summer project within our Engineering team. This role will center on developing a predictive model of laminated material deformation through our manufacturing processes.
This is a hands-on opportunity to work on a well-defined, technically meaningful problem with direct application to production. The intern will collaborate with engineering and operations teams to translate real-world process data into a usable predictive tool that supports new product development and process optimization.

Requirements

• Currently pursuing a BS or MS in Mechanical Engineering, Materials Science, or a related field.
• Coursework in Mechanics of Materials (required).
• Strong analytical and problem-solving skills.
• Ability to translate real-world physical behavior into mathematical models.
• Experience with data analysis tools (e.g., Excel, MATLAB, Python, or similar).
• Strong attention to detail and data accuracy
• Ability to work independently on a defined project while collaborating cross-functionally
• Clear communication skills, including the ability to explain technical concepts
• Curiosity and willingness to test, iterate, and refine assumptions
• Comfort working in a fast-paced, manufacturing environment

Nice To Haves

• Exposure to thermal processes, material deformation, or predictive modeling is a plus.
• Experience with simulation tools (e.g., FEA or similar) is a bonus.

Responsibilities

• Develop a predictive, equation-based (analytical) model to estimate deformation (e.g., shrinkage) of laminated materials during manufacturing processes.
• Utilize existing in-line measurement data and lookup tables from current products as a baseline.
• Expand from product-specific data to a generalized model capable of predicting behavior for new product designs prior to production.
• Validate model outputs against observed manufacturing data and refine for accuracy.
• (Optional/Bonus) Develop a computer-based simulation model to complement the analytical approach.
• Analyze material behavior data collected from manufacturing processes.
• Translate physical behavior into mathematical relationships and predictive equations.
• Build and document a generalized predictive model.
• Partner with engineering teams to validate assumptions and results.
• Present findings, methodology, and recommendations at the conclusion of the internship.
• Document work in a format that can be maintained and expanded by the team.

Benefits

• At CelLink, we believe that each employee should have the opportunity to become a CelLink shareholder through participation in CelLink's discretionary employee stock option plan.
• You'll also receive comprehensive medical and dental coverage and other great benefits.
