Mechanical CAD Design Engineer Needed for Injection-Molded Silicone Consumer Product

We are developing an innovative Soap-Dispensing Silicone Body Scrubber for mass production. The product consists of multiple plastic and silicone components assembled into a waterproof handheld device with a passive soap dispensing mechanism. We already have: Product concept Photos Videos Reverse-engineered engineering specification document Functional requirements We are looking for an experienced Mechanical Product Design Engineer to convert the concept into a manufacturing-ready CAD design suitable for injection molding and mass production. This is NOT a rendering or visualization project. The final design must be ready for tooling and manufacturing. Project Requirements The engineer must: 1. Create Complete 3D CAD Design Design every component including: Main body housing Silicone brush head Silicone bristles Internal soap chamber Push plug Bottom removable cap Travel cap Shower holder All internal ribs Snap-fit mechanisms Drainage channels Waterproof sealing features 2. Design for Manufacturing (DFM) The product must be optimized for injection molding. The design should include: Uniform wall thickness Proper draft angles Ribs Bosses Snap fits Injection molding best practices Mold-friendly geometry Manufacturing tolerances Cost optimization 3. Silicone Engineering Design the silicone components suitable for LSR molding including: Silicone bristles Wiper seal Silicone-to-plastic interface Bonding recommendations 4. Waterproof Design Design sealing features to minimize water ingress while maintaining proper drainage and easy cleaning. 5. Assembly Design Design an assembly that: Requires minimal parts Uses snap-fit assembly Requires no screws Is easy to manufacture and assemble 6. Engineering Validation Review the complete design to ensure: Manufacturable Cost-efficient Durable Suitable for mass production Deliverables The final delivery must include: 3D CAD Files STEP (.STEP) Native SolidWorks files (.SLDPRT / .SLDASM) or Fusion 360 source files Technical Drawings For every part provide: Fully dimensioned drawings Tolerances Section views Material specifications Critical dimensions Draft angles Assembly Package Exploded assembly Bill of Materials (BOM) Assembly drawing Part numbering Manufacturing Package Design suitable for: Plastic Injection Molding LSR Silicone Molding Production Tooling Preferred Skills The freelancer should have experience with: Mechanical Engineering SolidWorks Plastic Product Design Injection Molding DFM (Design for Manufacturing) Consumer Product Design Snap-Fit Design Waterproof Product Design Silicone (LSR) Products Please include examples of similar manufactured products in your proposal.
