• Post-Processing & Finishing: Perform and oversee post-processing operations (cleaning, sanding, deburring, bonding, surface finishing, and assembly) to ensure finished parts meet strict engineering and design specifications.
• Continuous Improvement: Experiment with build setups and materials to improve process consistency and identify operational inefficiencies within the lab.
• Collaboration: Maintain full communication with the immediate team and greater national department.
• Lab Maintenance & Logistics: Adhere to 5S and safety protocols, manage raw material inventory, and support incoming/outgoing part shipping logistics.

Qualifications

• Experience: 2-4 years of hands-on experience in a technical additive manufacturing, prototype lab, or R&D environment.
• Technical Aptitude: Demonstrated near-full understanding of machine operations, slicing/build preparation software, and material properties across key 3D printing technologies.
• Autonomy & Judgment: Proven ability to handle moderately complex assignments, exercise sound technical judgment, and work semi-independently with minimal supervision.
• Education: High school diploma or GED required; Technical certification or Associate degree in a related technical discipline is preferred.
• Software & Tools: Hands-on proficiency with Stratasys and FormLabs machines.
• Soft Skills: Open to constructive feedback, strong peer-to-peer and departmental communication skills, and a strong work ethic.
• Physical Requirements: Ability to stand for extended periods and lift up to 50 lbs.
