Job summary

Scrap Labs in Boulder, CO is seeking a hands-on Mechanical Engineer, Machine Design to design, build, and validate mechanical systems for our metal 3D printer platform. You will own hardware from concept through working reality, spanning CAD, prototyping, assembly, test, and iteration.

Join a small, high-output team, collaborate across disciplines, optimize for speed, reliability, and manufacturability, and contribute to rapid iteration in a fast-paced prototyping environment.

Qualifications

• Bachelor's degree in Mechanical Engineering or related engineering discipline.
• Experience using a CAD design package, SolidWorks strongly preferred.
• Demonstrated hands on mechanical experience through project teams, internships, or professional experience.
• Ability to translate an idea into physical hardware through iterative prototyping and debugging.

Responsibilities

• Design, build, and activate mechanical subsystems for a metal powder bed fusion (SLM) 3D printer platform, including structures, mechanisms, motion assemblies, thermal hardware, enclosures, and powder handling interfaces.
• Develop the factory in a lab approach, rapid prototyping, test driven iteration, and design for assembly improvements to accelerate build speed and reliability.
• Collaborate across disciplines, electrical, firmware or software, optics or laser, and process development, to influence system architecture and interfaces.
• Execute structural sizing, mechanism design, hardware fabrication support, and development testing to deliver functional prototypes and production intent designs.
• Create detailed CAD models and engineering drawings in SolidWorks, manage large assemblies and configurations with clean revision control.
• Perform engineering hand calculations and basic analysis to size structures, fasteners, mechanisms, and interfaces.
• Support manufacturing planning and build execution, machining, sheet metal, welding, vendor sourcing, and assembly procedures.
• Own test fixtures and validation setups, document results, and drive design changes based on real world data.
• Improve reliability and serviceability through thoughtful design, tolerance strategy, and practical GD&T application.
