Mechanical 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.

Required Background

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

4 + years experience in product design, preferably in medical devices.

Hands-on with prototyping, GD&T, and industrial design collaboration.

Skilled in material selection and tolerance control.

CAD : SolidWorks, Creo.

Familiar with IP rating design, drop testing, and vibration specifications.

FEA for stress / thermal validation (optional).

Exposure to ISO 13485 documentation for design traceability would be an added advantage
