Wireless Design Hardware Engineer - Multi-Radio Coexistence

# Wireless Design Hardware Engineer - Multi-Radio Coexistence


Job Number: 113721932

Santa Clara Valley, California, United States

Posted: 27-Apr-2018

Weekly Hours: 40.00


**Job Summary**

o The successful candidate will take responsibility for the overall system performance of multi-radio coexistence across a wide variety of products, for various wireless technologies including Cellular, WiFi, BT, GPS and NFC.

o The candidate will work closely with internal and external engineering groups (such as Mechanical Engineering / Product Design, RF Hardware Design, Antenna, System EE, Wireless Software, ATE/factory automation engineers, contract manufacturers, and part / equipment vendors) to debug multi-radio co-existence issues and implement improvements in the design.



**Key Qualifications**

* Solid understanding of RF hardware and system design. Some HW system design experience is preferred.

* Understanding of EM and antenna theory inside portable wireless devices is a plus, including proper grounding, isolation, and desense mitigation techniques

* Solid understanding of RF component characteristics and behavior. Hands-on experience is a plus.

* Experience with performing sensitivity / RvR tests in both conducted and radiated environments

* Able to perform hands-on disassembly and make experimental modifications to intricate hardware

* Strong problem solving and analytical skills, including organization skills.

* Experience with RF lab equipment including spectrum analyzer, power meter, network analyzer, vector signal generator/analyzer, oscilloscope, cellular box, and/or WiFi/GPS emulator.

* Basic technical reporting, presentation and communication skills.

* Some level of experience with current and upcoming RF Standards is favorable.

* Knowledge of Wireless Co-Existence HW design and SW mitigation schemes is a plus, for example WCI.

* Ability to travel frequently to international sites, factory travel is expected to be 20%

* Energy and drive to thrive in start-up environment. Highly motivated, a self-starter, and a team player.


**Description**

The candidate would be tasked with:

- Defining multi-radio co-existence performance requirements and test methodology.

- Ensuring that the product is designed to meet those requirements, both on a conducted and radiated level. This includes giving design guidelines, reviewing, and signing-off on all PCB and flex layouts, and system-level grounding / shielding / etc, related to multi-radio coexistence.

- Designing and implementing test systems both in a lab and manufacturing environment, to validate the design performance.

- Supporting manufacturing test and debug / failure analysis efforts on-site, through international travel. Interpreting large amounts of statistical data across a wide range of test cases, across multiple wireless technologies.

- Debugging and resolving product design and test issues that arise. This includes hands-on mockup and proposal of design changes to resolve any issues found.

- Innovating to develop implementable design solutions that optimize product performance. This includes coming up with HW, FW, SW solutions and system algorithms to mitigate against any coexistence issues.

- Managing the process to ensure our products meet all multi-radio co-existence performance specifications.


The candidate would also be tasked with understanding all applicable wireless technologies (such as IEEE 802.11, Bluetooth, GPS/GLONASS, NFC, GSM, UMTS, CDMA and LTE) and industry standard (such as 3GPP, WiFi Alliance, IEEE, and Bluetooth SIG) in relation to our products.


**Education**

This position requires a BS in Electrical Engineering with 3 years or above of relevant work experience or an MS in Electrical Engineering with 1 year or above of relevant work experience.


**Additional Requirements**
