You’ll work in an exceptionally clean, climate-controlled environment alongside experienced toolmakers and engineers while building precision molds from start to finish. The company promotes from within, offers strong long-term career growth, and provides a collaborative team environment where craftsmanship and technical expertise are truly valued.
