Job Description

Mechanical Design Engineer - Product Development (Plastic Parts)

Location

Ahmedabad, India (On-site)

Employment Type

Full-time

Role Overview

We are looking for a hands-on Mechanical Design Engineer who can take industrial design sketches, concepts, and rough CAD and convert them into production-ready mechanical designs suitable for injection molding and precision machining.

This is not a styling or visualization role. This role sits at the intersection of industrial design intent and real-world manufacturing constraints. You will be responsible for making designs that can actually be manufactured, assembled, tested, and scaled.

You will work closely with industrial designers, prototyping vendors, and internal R&D teams to deliver robust, cost-effective mechanical designs.

Key Responsibilities

Core Design Responsibilities

Convert industrial designer sketches, surfaces, and concepts into fully constrained, parametric CAD models Develop manufacturable part designs with correct wall thickness, ribs, bosses, draft angles, fillets, shut-offs, and undercut strategies Own Design for Manufacturing (DFM) for injection molding and machining Prepare production-grade CAD (not presentation CAD)
Manufacturing & DFM

Design plastic parts for injection molding, including:

Draft analysis Parting line strategy Moldability considerations Shrinkage and tolerance stack-ups Design machined components considering: Tool access Standard cutters Cost-effective machining strategies Work on assembly design, fasteners, snap-fits, inserts, and tolerances
Documentation & Handover

Create 2D manufacturing drawings with GD&T where required Prepare BOMs, exploded views, and assembly drawings Support vendors during prototyping and early manufacturing runs Incorporate feedback from machinists, molders, and fabricators
Prototyping & Iteration

Support rapid prototyping (3D printing, CNC, soft tooling) Iterate designs based on functional testing and real-world feedback Participate in design reviews and failure analysis
Required Skills & Experience

Mandatory

Bachelor's degree in

Mechanical Engineering

Strong proficiency in

SolidWorks

Solid understanding of

injection molding design principles

Practical knowledge of

machining processes

(CNC, turning, milling) Ability to convert

aesthetic concepts into manufacturable designs

Experience designing

plastic housings, enclosures, and mechanical parts

Preferred

Experience working with

industrial designers

Exposure to

medical devices, consumer products, or electro-mechanical assemblies

Understanding of

tolerance stack-ups and fits

Experience with

prototyping and vendor coordination

Familiarity with

DFMEA / basic product validation workflows

What This Role Is NOT

Not a pure CAD drafting role Not a surface-modeling or visualization role Not a styling or rendering position
If you cannot justify why a part can be molded or machined the way you designed it, this role is not a fit.

What We Offer

Hands-on exposure to real product development and R&D Work on end-to-end product development, not isolated CAD tasks Opportunity to grow into Lead Mechanical Engineer / Product Architect Direct involvement in manufacturable, real-world products
How to Apply

Please apply with:

Updated resume Portfolio or sample work (manufactured products preferred) Brief note explaining your experience with injection molding design
