Computer Aided Design Designer

Function: Engineering / Design

Experience: 4+ Years

Qualification: B.E. / B.Tech / Diploma

Software: SolidWorks (Expert)

Location: IIT Madras Research Park (onsite, no WFH)

Salary: As per industrial standards

We are looking for a technically rigorous and detail-oriented CAD Designer with hands-on experience in regulated, high-stakes industries specifically medical devices (Class C / Class D), aerospace, or automotive. The ideal candidate brings a strong manufacturing mindset to every design decision, understanding that great engineering lives at the intersection of precise geometry and producible parts.

This role demands mastery of SolidWorks, fluency in surface modelling, and a thorough command of GD&T, ASTM drawing standards, and the documentation rigour that Class C/D regulatory environments demand.

Develop, maintain, and revise 3D CAD models and 2D engineering drawings using SolidWorks, ensuring compliance with ASTM drawing standards and internal design controls.

Execute surface modelling for complex geometries including organic and freeform surfaces typical in Class C / Class D medical device components.

Apply GD&T (per ASME Y14.5) accurately on all drawings; interpret and review supplier drawings for GD&T compliance.

Collaborate closely with manufacturing, quality, and R&D teams to ensure designs are producible, cost-effective, and aligned with DFM/DFA principles.

Generate and manage engineering BOMs, drawing revisions, and ECOs within a PLM/PDM environment.

Support design verification and validation (V&V) activities, DHF documentation, and design reviews in compliance with ISO 13485 or AS9100 quality systems.

Perform tolerance stack-up analyses (worst-case and RSS) to validate assembly fit, form, and function.

Liaise with tooling, machining, and fabrication vendors to troubleshoot manufacturability issues and drive design improvements.

Create and maintain PPAP / FAI documentation where applicable, particularly for precision-machined or injection-moulded components.

Conduct FEA-informed design iterations in coordination with simulation teams or directly using SolidWorks Simulation.

Education

B.E. / B.Tech in Mechanical Engineering, Production Engineering, or a related discipline. Diploma holders with demonstrated industry experience in regulated sectors may also apply.

Experience

Minimum 4 years of hands-on CAD design experience in at least one of the following: Medical Devices (Class C / Class D preferred), Aerospace & Defence, Automotive / EV Systems.

Demonstrable experience designing components that went through full product lifecycle from concept through to production release and sustaining engineering.

Prior exposure to design under a formal Quality Management System (ISO 13485, ISO 9001, AS9100, or equivalent).

Technical Skills

SolidWorks Expert level: Part, Assembly, Drawing, Surface, Weldments, and Sheet Metal workspaces.

Surface Modelling proficiency in Class A / freeform surfaces, curvature continuity, and complex loft/sweep geometries.

GD&T deep working knowledge per ASME Y14.5; ability to independently define and review datum schemes, feature controls, and tolerancing strategies.

ASTM Drawing Standards familiarity with relevant ASTM standards governing technical drawings and material callouts.

DFM / DFA ability to critique designs for machinability, mouldability, assembly ease, and cost efficiency.

Tolerance Stack-Up Analysis proficiency in 1D/2D worst-case and RSS methods.

PDM / PLM Systems experience with SolidWorks PDM, Windchill, Vault, or similar.

Manufacturing Processes solid understanding of CNC machining, injection moulding, casting, sheet metal fabrication, and surface finishing processes as they relate to design decisions.

CSWA / CSWP (Certified SolidWorks Associate / Professional) certification.

Experience with Class C or Class D implantable or life-sustaining medical device design (e.g., cardiovascular, orthopaedic, surgical instruments).

Working knowledge of FEA using SolidWorks Simulation, ANSYS, or equivalent.

Familiarity with IEC 60601, ISO 14971 (risk management), or MIL-SPEC standards.

Exposure to DFMEA / PFMEA processes.

Experience working with contract manufacturers (CMs) or CMOs in a regulated environment.

Knowledge of biocompatible materials (ISO 10993) or aerospace-grade alloys and their machinability.
