Medical Device Design Engineer

Job Purpose

Design and develop mechanical systems including enclosures and complex mechanisms for a point of-care diagnostic device that processes diverse biological samples. Ensure robust, ergonomic, and manufacturable integration of hardware with optical, fluidic, and electronic subsystems.

Key Responsibilities :

• Design device housing and mechanisms that accommodates all subsystems while protecting sensitive components from impact, moisture, and contaminants.
• Develop mechanical interfaces such as cartridge slots, hinges, latches, and other user-operated parts.
• Design and Develop Test kits that work in tandem with the devices.
• Ensure structural integrity under drop, vibration, and transport stresses.
• Design effective thermal pathways or vents to manage heat from LEDs, motors, and electronic components.
• Demonstrate deep knowledge of both conventional and non-conventional manufacturing processes.
• Apply Design for Manufacturability and Assembly (DFMA) principles to optimize parts for plastic molding, sheet metal fabrication, and 3D printing based on production volume.
• Conceptualize the manufacturing processes and tools required, including robotics, AI based inspection systems, jigs, fixtures, etc.
• Integrate self-aligning features and fastening strategies that reduce assembly time and errors.
• Rapidly prototype concepts using 3D printing, CNC, Casting and similar technologies.
• Perform cycle testing for mechanisms and device and execute ingress protection and environmental testing as required.
• Maintain detailed and parametric CAD models, technical drawings, and part libraries.
• Generate Bills of Materials (BOMs), exploded views, and tolerance stack-ups to support production readiness.
• Work on developing vendors to support volume production of the designed parts. Have elaborate project planning to ensure deliverables are achieved on time.
