• Blueprints & Geometric Dimensioning: Solid understanding of technical drawing standards, blueprint reading, and a basic familiarity with Geometric Dimensioning and Tolerancing (GD&T).

• Core Competencies: Strong spatial reasoning, mathematical aptitude, and problem-solving skills with a high degree of attention to detail.

• Soft Skills: Eagerness to learn, strong communication skills, and a collaborative mindset suited for a fast-paced manufacturing environment. Preferred (But Not Required) Qualifications

• Prior internship, co-op, or hands-on experience in a machine shop or manufacturing environment. • Basic understanding of plastic materials, metallurgy, or manufacturing processes.

• Exposure to mold simulation software (e.g., Moldflow)
