Prototyping Specialist

About the role

We are looking for a hands‑on, results‑oriented Prototyping Specialist to join our engineering team in Waltham. You will manufacture prototype components, improve fabrication processes, and support product innovation through a variety of manufacturing technologies.

Key responsibilities

• Manufacture prototype parts for new product development and engineering validation.
• Program, set up, and operate 3‑axis CNC milling equipment to produce precision components.
• Perform post‑processing, inspection, and quality verification of machined parts.
• Fabricate non‑CNC components using manual mills, lathes, metal‑cutting, forming, woodworking, welding, brazing, and fiberglass lay‑up.
• Produce prototypes with FDM and SLA 3D‑printing technologies, including finishing.
• Assemble fabricated parts into functional prototype assemblies.
• Collaborate with engineers to modify designs and develop manufacturable solutions.
• Recommend improvements to methods, materials, and designs for better manufacturability and efficiency.
• Estimate timelines, prioritize work, and communicate status to stakeholders.
• Maintain a safe, organized shop, perform preventive maintenance, and calibrate CNC equipment.
• Monitor inventory of materials, tooling, and supplies, coordinating replenishment as needed.
• Identify and implement continuous‑improvement initiatives.

Required profile

• Hands‑on mindset with a passion for solving technical challenges.
• Experience working with a wide range of manufacturing technologies.
• Ability to collaborate closely with engineering teams and adapt designs for production.
• Commitment to safety, quality, and continuous improvement.

Required skills

• 3‑axis CNC milling operation and programming.
• Manual machining (mills, lathes) and metal‑cutting/forming.
• Woodworking tools, welding, brazing, and fiberglass lay‑up.
• FDM and SLA 3D‑printing, post‑processing, and finishing.
• Inspection, quality verification, and preventive maintenance of shop equipment.
• Inventory management of materials, tooling, and supplies.
• Advanced CNC programming strategies and emerging additive manufacturing techniques (preferred for highly qualified candidates).

What we offer

• Opportunity to work in a global technology leader focused on innovation.
• Access to diverse manufacturing equipment and cutting‑edge prototyping tools.
• Collaborative environment that values continuous learning and professional growth.
