Automation Engineer (Validation Engineer)- Wifi

Role : Automation Engineer (Validation Engineer)

Responsibilities :

• The candidate will work with professional lab test equipment (e.g., Candela, Octoscope and/or Veriwave WiFi equipment, spectrum analyzers, network analyzers).
• Write detailed test plans, test cases, methodically document the test steps and results
• The candidate will primarily work on testing and debugging WiFi mesh networking equipment, including router (Residential Gateway) and mesh extenders in a lab setting as well as in real-life environments.
• The candidate will validate WiFi connectivity: Test peak and average throughput, maximum connectivity, airtime fairness, latency, rate-vs-range, mesh roaming, MU-MIMO performance, spatial consistency, collect RSSI and SINR from routers and WiFi clients to measure coverage.
• The candidate will work with multiple vendor equipment: Validation, qualification, vendor comparison.
• The candidate will write TR-069 related shell scripts to control WiFi devices, orchestrate test scenarios, and collect KPIs. Scripts need to be modified to handle differences between vendors (e.g. number ethernet ports, wifi radios and supported number of SSIDs).

Job Description:

Prior experience with WiFi performance testing is required. Familiarity with Octoscope, Candela or Veriwave test equipment is a MUST.

• 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 tools is required. Familiarity with L3-networking / routers is a plus.
• Good knowledge of device management protocols like TR-069.
• 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 a plus.
• 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.
