Mechanical Design Engineer

Qualtech Telesys; Bengaluru; On-site; INR 600,000 - 900,000; Full time

Job summary

Qualtech Telesys in Bengaluru seeks a hands-on mechanical designer to craft electronic enclosure solutions for smart home and related products, balancing aesthetics, manufacturability, thermal performance, and electrical safety.

You will design plastic and sheet-metal enclosures, consider PCB mounting, cable routing, ventilation, and serviceability while coordinating with PCB, electronics, firmware, and industrial-design teams. Knowledge of IP ratings and flame-retardant materials is required.

Qualifications

• Hands-on experience in electronic enclosure design for consumer electronics, IoT products, electrical panels, smart switches, controllers, gateways, adapters, or similar products.
• Strong knowledge of enclosure features such as screw bosses, snap fits, ribs, living hinges, heat staking, ultrasonic welding, gasket grooves, cable routing, PCB supports, connector cut-outs, and ventilation.
• Knowledge of PCB-to-enclosure integration, tolerance stack-up between PCB, touch glass, display, connectors, and external housing components.
• familiarity with materials used for electronic enclosures, including ABS, PC, PC-ABS, FR-grade plastics, nylon, aluminum, sheet metal, silicone, and rubber.
• Understanding of thermal management, electrical safety, IP rating concepts, EMI/EMC-related mechanical provisions, and serviceability requirements.

Responsibilities

• Lead the mechanical design and development of electronic enclosures for smart home panels, control modules, adapters, gateways, and related products.
• Design plastic and sheet-metal enclosures considering PCB mounting, connector access, cable routing, ventilation, heat dissipation, assembly sequence, screw bosses, snap fits, ribs, clips, and service access.
• Ensure enclosure designs meet electrical safety requirements, including creepage and clearance considerations, insulation barriers, earthing provisions, flame-retardant material selection, and protection against accidental contact with live parts.
• Coordinate with PCB, electronics, firmware, and industrial-design teams to ensure correct placement of displays, touch glass, LEDs, buttons, connectors, antennas, sensors, relays, and power components.
• Design for IP protection requirements where applicable, including gasket selection, sealing features, cable entry protection, and dust/moisture resistance.
• Evaluate thermal performance of enclosures for high-load modules, power supplies, relays, and other heat-generating electronic components.
• Review enclosure prototypes for fitment, aesthetics, structural strength, touch-panel alignment, PCB clearances, connector accessibility, and ease of assembly.
