The position requires strong expertise in product design, prototyping, and manufacturing processes within a regulated MedTech environment.

Key Responsibilities

• Design device enclosures and mechanisms to protect sensitive components from environmental factors.
• Develop mechanical interfaces such as cartridge slots, hinges, latches, and user-operated parts.
• Design test kits that integrate with device functionality.
• Ensure structural integrity under drop, vibration, and transport conditions.
• Design thermal management systems for electronic and optical components.
• Apply DFMA principles for plastic molding, sheet metal, and 3D printing.
• Conceptualize manufacturing processes, tools, fixtures, and automation systems.
• Integrate self-aligning features to reduce assembly time and errors.
• Prototype designs using 3D printing, CNC, and casting techniques.
• Perform testing including cycle testing, ingress protection, and environmental validation.
• Create CAD models, technical drawings, BOMs, and tolerance stack-ups.
• Collaborate with vendors for production readiness and scaling.
• Plan and manage projects to meet timelines and deliverables.

Education & Certification

• B.E. or M.E. in Mechanical Engineering or Product Design Engineering.

Required Skills

• 6+ years of experience in product design, preferably in medical devices.
• Hands-on experience in prototyping, GD&T, and industrial design collaboration.
• Strong knowledge of material selection and tolerance control.
• Proficiency in CAD tools such as SolidWorks or Creo.
• Familiarity with IP rating design, drop testing, and vibration standards.
• Knowledge of FEA for stress and thermal validation (preferred).
• Exposure to ISO 13485 documentation and design traceability (advantage).
