Durban: Design for Manufacturing (DFM) Reviewer – Engineering/Manufacturing – Remote

About the Role

We are seeking a skilled Design for Manufacturing (DFM) Reviewer to join our client’s team and play a key role in ensuring designs meet manufacturability and quality standards. As part of their continued growth, they are building a labelled dataset of mechanical CAD parts annotated with DFM attributes for Computer Numerical Control (CNC) machining and injection moulding.

Key Responsibilities

• Review 3D CAD geometry (parasolid files) and apply structured DFM labels across a large library of mechanical parts
• Identify and label features such as deep pockets, thin walls, undercuts, poor tool access, non-standard radii, tight tolerances implied by geometry, and setup count drivers for CNC machining
• Identify and label draft angle violations, sink risk zones, undercuts requiring side actions or lifters, wall thickness non-uniformity, weld line risk areas, and gate location constraints for injection moulding
• Apply severity ratings and flags (e.g., “minor rework,” “requires special tooling,” “mold-breaking feature”) consistently across parts
• Work within a structured labelling taxonomy — providing feedback to refine and expand label categories where the schema falls short
• Validate labels for consistency and flag ambiguous cases for review

Requirements

Hands-on experience in CNC machining, injection moulding, or DFM review in a manufacturing or engineering services context

Strong ability to read and interpret 3D CAD geometry — you don’t need to model, but you need to look at a geometry file (STEP) and immediately identify manufacturability issues

Experience performing or reviewing DFM analyses in a production context (not just academic)

Systematic, detail-oriented approach — labelling work requires consistency above all else

Qualifications

• CNC-Specific Knowledge: Deep familiarity with milling, turning, and multi-axis machining constraints Understanding of tool access, fixturing, setup count, and feature geometry relative to standard tooling Ability to identify features that require 4- or 5-axis capability vs. standard 3-axis Knowledge of standard radii, thread types, and tolerance conventions that affect cost
• Injection Molding-Specific Knowledge: Deep familiarity with draft angle requirements, parting line placement, and ejection constraints Understanding of wall thickness guidelines, rib-to-wall ratios, and sink/warp risk Ability to identify undercuts and classify the tooling action required (side action, lifter, collapsible core) Familiarity with gate types, runner systems, and their geometric implications on part design
