  • Perform tasks pertaining to CPE validation & automation
  • Write TR-069 related scripts
  • Software automation using tools like Python and Expect
  • Write new command line tools in Java, Python, or Go
  • Write shell scripts to validate CPE (i.e. TR-069 routers) on the network
  • Customize scripts per vendor including ports, wifi radios, SSID packets, etc.
  • Generate TPut, KPI, and other performance metrics for the devices being tested

Scope / Timeline / Sample task-list

  • 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 professional lab test equipment (e.g., Octoscope or Veriwave Wi-Fi equipment, spectrum analyzers, network analyzers).
  • The candidate will work with multiple vendor equipment: Validation, qualification, vendor comparison.
  • The candidate will develop an automation framework for lab test setups and OSS integration.
  • 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). 
  • The candidate will develop new command line tools to collect periodic statistics, ideally written in Java or Python or Go (preferably Java).
