Key job responsibilities

The primary responsibility of this role is to design and deliver wireless solutions including schematic/layout on WiFi/BT/WAN/GPS/ZB/Lora related products and co-work with other cross function team to detect/Debug any wireless issues to ensure the performance and product is suitable for mass production in high volume. The candidate will get involved in innovative process improvement, technology initiatives and experiment his own ideas that improve cost, quality and customer experience.

• Work within a project team and take responsibility for wireless technology implementation such as WAN, WiFi, BT etc, and wireless system performance optimization.

• Wireless system performance and RF specification definition based on device architect, business model and other predefined functions.

• Design, Simulate, implement, validate and optimize RF circuitry (including schematic and PCB layout) and system performance.

• Meet with vendors and technology suppliers to key components selection and qualification.

• Characterize RF test coverage, system de-sense, and EMI issues to meet requirements

• Perform simulations for RF design and de-sense mitigation

• Take the product through development, compliance testing, operator testing, ramp up and sustaining

• Support radiated manufacturing test and defects in the factory

• Optimize and improve any defect process from design/validation/manufacturing

We are open to hiring candidates to work out of one of the following locations:

Shenzhen, 44, CHN

Basic Qualifications

• Electrical Engineering degree, with hands on experience in designing and debugging RF circuits and wireless system, failure analysis and functional verification.
