What you will do:
- Understand system requirements and architecture in depth.
- Define, develop, and execute advanced test methodologies for validating end-to-end system level functionality and performance (lab & field) across the mobile protocol stack (PHY, MAC/RLC/PDCP, RRC, NAS, Data, TCP-IP/UDP).
- Execute manual and automated testing of wireless systems, including functional and performance testing.
- Ensure timely execution, test accuracy and repeatability.
- Document test results, test coverage and other KPIs and communicate to all stakeholders regularly.
- Deep-dive into test results and root-cause issues and communicate with the appropriate teams.
- Responsibilities will also include defining Key performance Indicators and conducting modem performance evaluation.
- Design lab setups for various types of tests, including conducted clean channel and fading channel test and field tests.
- Build racks and other test-rigs as necessary for executing the test plan.
- Automate the test execution including control and configuration of test equipment.
- Collaborate with multi-disciplinary teams – hardware, software, mechanical, systems, etc. – in different time-zones to ensure that system requirements will be met during operation.
What you bring to this role:
