Nice To Haves

Experience with ceramic matrix composites (CMCs)
Background in tool making for composite parts
Experience in R&D or early-stage manufacturing environments
Ability to operate independently in a fast-paced, low-structure setting

Responsibilities

Develop and refine layup processes for high-temperature composite materials, including prepreg-based CMC panels
Execute hands-on layup, molding, and fabrication activities to support rapid development and testing
Establish and maintain standards for consumables, layup techniques, and shop processes
Support tooling design and fabrication for composite part production
Partner with engineering to iterate on materials and process development
Document processes and ensure repeatability as production scales
