Budget: $15 – $25 AUD

Mechanical Engineer – Plastic Injection Molding Expert for Product Component Design & Mold Development
Description:
We’re looking for a highly skilled mechanical engineer with deep expertise in plastic injection molding to assist in the selection, specification, and integration of mechanical components for a consumer product. The role will involve evaluating snap-fit and latch mechanisms, optimizing plastic part design for manufacturing, and collaborating on mold-ready files.

Key Responsibilities:

Review and refine design concepts with a focus on manufacturability and mold cost

Assist in selecting suitable mechanical latch or push-to-open systems compatible with injection molding

Design or adjust internal components and mounting features (e.g., snap-fit tabs, detents, hinge points, spring cavities)

Provide DFM (Design for Manufacturing) recommendations

Develop or refine mold-ready 3D files and 2D technical drawings

Collaborate with us to prepare for tooling and supplier handover

Proven experience in plastic injection molded product development

Deep knowledge of materials like ABS, PP, PC, and POM

Familiarity with latch, snap-fit, or push-to-open component design

Ability to generate DFM-compliant files for multi-part assemblies

Experience working with mold makers or factories (especially China-based)

Proficiency in CAD software (SolidWorks, Fusion 360, or similar)

Excellent communication and willingness to iterate quickly


Deliverables:

Final 3D CAD files (STEP, IGES)

DFM-ready designs for injection molding

Technical drawings for each part with tolerances

Component specification for latch/closure system
