Top 3 Daily Tasks:

Lead schematic design for efficient, high-performance, and low-power electronic subsystems used in wearable and immersive devices. Drive component selection, qualification, and BOM optimization balancing performance, reliability, and cost. Run simulations, signal integrity checks, and detailed power analysis to validate and optimize system behaviour.

Role and Responsibilities:

Design digital electronic circuits with high-speed interfaces and microprocessor-based architectures. Implement complex hardware architecture design and build scalable, modular electronic systems. Design scalable and modular electronic circuits with efficient assembly planning. Define performance parameters for Signal Integrity (SI), Power Integrity (PI), Thermal Analysis, and Load Analysis for SoC-based systems. Design boards as per EMI/EMC certification requirements and support compliance validation. Define and document power system architecture and specifications. Support vendor selection and drive component evaluation and qualification. Design and test circuits and firmware interfaces for static and dynamic power systems. Work hands-on with SoCs, ASICs, sensors, and mixed-signal systems. Perform board bring-up, debugging, validation, and lab testing activities. Collaborate closely with firmware, mechanical, and manufacturing teams for full system integration.

Minimum Work Experience Required: 5–8 years of hands-on experience in hardware design, preferably in consumer electronics, embedded systems, wearables, AR/VR devices, or high-performance embedded platforms.

Top 5 Skills You Should Possess:
