Job Description
As a Wireless Validation Engineer you will develop document execute & debug unit and system-level validation tests for network-connected devices and analyze wireless performance for various different use-cases. This includes mission-critical 4G-LTE 5G-NR Wi-Fi and GNSS wireless interfaces integrated with vehicle and cloud-based networks. You will collaborate with FW engineers to ensure performance meets quality of service targets and other key metrics including throughput latency jitter. You will be hands-on to develop test-cases and execute test frameworks for prototypes and commercial system releases as well conduct tests in the field ensuring network compliance with international regulations. We seek an expert enthusiastic innovative and self-starting individual to join our team.
In this role you will:
- Develop and execute tests conduct hands-on functional performance testing on wireless and fixed networks in-house and via external labs. Analyze 4G-LTE 5G-NR Wi-Fi GNSS Ethernet and IP behavior internally and with partners. Identify root causes of failures whether found internally or externally.
- Develop Test Infrastructure - Select procure commission and configure test cases on network emulators and related test equipment supplied by vendors such as Keysight or Rohde & Schwarz. Develop custom test assets setups and scripts to enable efficient testing including scripts using Python and TTCN. Construct and maintain lab infrastructure from fixed network test harnesses to RF cabling.
- Being hands-on explore opportunities for improvement relying on diagnostics analytics lab/test equipment experimentations as well as code/architecture reviews.
