Job Description

Ruckus Wireless invented the first-of-its-kind smart-WiFi technology that delivers the best wireless performance in the industry (http://www.ruckuswireless.com/technology/). We are obsessed with WLAN performance. We are creating an engineering position "Wireless System Performance Czar" with the mission to ensure new Ruckus products always keep the industry lead.

The performance engineer will work closely with CTO and selected senior development engineers during the critical stages of new product/feature development, interactively working to gather performance data and design new test methodologies to provide direct feedback into the design process therefore ensuring rapid convergence and design optimization.

The successful candidate will be responsible for deploying and maintaining wireless test networks required for the performance characterization of new designs (RF hardware and SW algorithm), developing data collection test tools, and performing data collection and data analysis activities in support of select advanced feature development projects.

Strong familiarity with switched and routed network topologies and protocols along with hands on experience with either the development or testing of 802.11 networks is required. Data analysis activities require solid analytic skills and familiarity with statistics. Familiarity with topics related to the RF physical layer such as rate adaptation, modulation methods, RF propagation and pathloss calculations, and antenna pattern characteristics is a significant plus.

Requirements

• B.S. CS or EE engineering degree. MS or Ph.D significantly desired.
• More than 3 years networking industry experience (SW development or SQA)
• Strong experience with 802.11 wireless systems

Required Skills:

• Python, C, Embedded Linux, Excel

Desired Skills

• Experience with Network Test Tools (e.g. Chariot, iperf)
