Description

Validate and automate testing for WiFi mesh networking equipment, including residential gateways and mesh extenders, in lab and real-life environments.

Responsibilities

• Test WiFi connectivity and performance metrics, including throughput, latency, mesh roaming, MU-MIMO, and airtime fairness.
• Develop an automation framework for lab test setups and OSS integration.
• Write TR-069 related scripts and shell scripts to control WiFi devices and orchestrate test scenarios.
• Build new command line tools in Java, Python, or Go to collect periodic statistics.
• Execute root-cause analysis and debug hardware/software issues using network analyzers and Wireshark.

Required Skills

• Prior experience with WiFi performance testing.
• Proficiency in software automation using Python and Expect.
• Strong knowledge of RF concepts including splitters, attenuators, antennas, and RF shielded boxes.
• Hands-on experience with lab equipment: spectrum analyzers, network analyzers, and oscilloscopes.
• Deep understanding of TCP/IP and L2 networking/switches.
• Ability to write shell scripts for CPE validation and TR-069 router testing.
• Experience with debugging tools and methodical root-cause analysis.
• Competency in Java, Python, or Go for tool development.
• Proficiency with Wireshark for network debugging.

Preferred Skills

• Familiarity with Octoscope or Veriwave Wi-Fi test equipment.
• Knowledge of L3 networking and routers.

Key Skills

Education

• Prior experience with WiFi performance testing is required. Familiarity with Octoscope, Veriwave test equipment is a plus. • Good knowledge of RF concepts is required: splitters, attenuators, antennas, RF shielded boxes. • Familiarity with lab test equipment is required: Spectrum analyzers, network analyzers, oscilloscopes. • Good knowledge of TCP-IP, and L2 networking / switches, wireshark debugging tool is required. Familiarity with L3-networking / routers is a plus. • Ability to write shell scripts to validate CPE (i.e. TR-069 routers) on the network is required. • Ability to customize scripts and run experiments per vendor; ports, wifi radios, SSID packets, etc. is required. • Background in software automation using tools like Python and Expect or other is required. • Prior experience with debugging tools, and root-cause analysis is required. The candidate must have good problem solving skills. • The candidate will generate TPut/KPI/other performance metrics and statistics for the devices being tested, compile test reports, to help prepare presentations. Good documentation skills are required.
