3D CAD Designer at Sproxil

Job Description

• We are seeking a highly skilled 3D CAD Designer with extensive experience in designing mechanical casings and assemblies for electronic devices.
• The ideal candidate will be proficient in SolidWorks or Fusion 360 or TinkerCad, capable of creating precise, functional, and manufacture designs optimized for 3D printing, injection molding, or other fabrication methods.
• The contractor will work closely with our product and engineering teams to transform concepts and electronic schematics into production-ready enclosures that meet technical, aesthetic, and usability requirements.

Key Responsibilities

• Design, model, and optimize 3D mechanical casings for electronic devices, including housings, snap-fits, and mounting features.
• Develop assemblies ensuring proper fit for PCBs, batteries, connectors, and other components.
• Prepare 3D-print-ready files (STL/OBJ/3MF) and support structures for prototyping.
• Collaborate with engineers to ensure clearance, tolerance, and accessibility for components.
• Conduct design reviews and iterate quickly based on feedback.
• Ensure designs adhere to manufacturing constraints, including 3D printing,injection or molding.
• Maintain organized libraries of CAD files, version history, and documentation.

Requirements
Qualifications:

• 5+ years of professional experience in mechanical CAD design for consumer electronics, IoT devices, or similar products.
• Expert proficiency in SolidWorks and/or Fusion 360 (parametric design, assemblies, sheet metal, surface modeling).
• Proven experience designing electronic device casings, including enclosures for PCBs, connectors, and batteries.
• Strong understanding of 3D printing processes, tolerances, and materials (PLA, ABS, resin, PETG, etc.).
• Experience with design for manufacturing (DFM) principles.
• Familiarity with file export for 3D printing (STL/OBJ/3MF), mesh repair, and slicer workflow.
• Excellent attention to detail, problem-solving skills, and ability to work independently.
• Strong communication skills to collaborate with cross-functional teams.

Benefits

• Competitive contract rate, commensurate with experience and scope of work.
