Primary Job Title:
Wireless (WLAN) Test Engineer

Role & Responsibilities

  • Design, author and execute comprehensive WLAN test plans (functional, performance, stress and regression) for 802.11ac/ax/ay/be devices across client and AP use-cases.
  • Perform RF and protocol measurements—throughput, latency, packet error rate (PER), RSSI, MCS, roaming and co-existence tests—using Spirent/Ixia/Keysight and OTA chambers.
  • Automate repeatable test flows and validation suites using Python, shell scripting and test frameworks to accelerate CI pipelines and reduce manual effort.
  • Capture and analyze packet traces (Wireshark/tcpdump), log files and kernel/firmware debug output to identify root causes and propose corrective actions.
  • Collaborate closely with firmware, RF and system engineers to reproduce issues, verify fixes, and validate performance across firmware revisions and hardware variants.
  • Maintain lab infrastructure, author clear test reports, track defects in issue trackers, and contribute to product release readiness and certification activities.

Skills & Qualifications
Must-Have

  • Bachelor's degree in Electronics, Telecommunications, Computer Science or equivalent plus 3+ years of hands-on WLAN testing or wireless system validation experience.
  • Practical experience with protocol stacks and RF/performance testing (throughput, PER, roaming, MIMO behavior).
  • Strong scripting skills (Python preferred) to build automation and parse test output; comfort with Linux-based DUT access and debugging.
  • Working knowledge of test equipment (Spirent/Ixia/Keysight/Anritsu), packet capture tools and OTA/chamber testing.
  • Excellent problem-solving, test-case design and written communication skills for concise bug reports and test documentation.

Preferred

  • Experience with Wi‑Fi Alliance certification processes, regulatory testing, and RF lab calibration.
  • Familiarity with CI/CD integration for test suites (Jenkins/GitLab), pytest or similar frameworks, and source control workflows (Git).
  • Exposure to modern Wi‑Fi features (OFDMA, MU‑MIMO, HE, EHT), 6GHz band testing and MLO concepts.

Benefits & Culture Highlights

  • Access to a fully equipped wireless R&D lab with industry-standard test gear and OTA facilities.
  • Opportunities for technical growth, certification support and cross-functional collaboration with firmware and RF teams.
  • Fast-paced, engineering-driven culture focused on ownership, measurable impact and product quality.

Interested candidates should be available to work on-site in India and comfortable operating in hands-on lab environments. Apply if you enjoy combining RF insight, protocol knowledge and automation to deliver high-quality wireless products.
