The Cellular 4G/5G System Performance Engineer joins a modem team within a silicon design group responsible for productizing state-of-the-art cellular SoCs. This role focuses on the embedded 5G/4G/multimode cellular system and firmware effort. You will collaborate with system engineers and firmware developers to understand design details, design performance verification lab use cases, and develop test scripts over lab network emulators to identify user equipment performance issues. Key responsibilities include troubleshooting performance-related issues and guiding test executors during validation. Required expertise includes 4G/5G physical layer, protocol stacks, and procedures. You must possess core computer science fundamentals and proficiency in Python, C/C++, or Java. Experience with Keysight, Anritsu, and R&S test equipment and their automation interfaces is essential for solving complex wireless system performance problems.

What you'll do

  • Design performance verification lab use cases and test cases to identify potential UE performance issues.
  • Develop test scripts over lab network emulators to implement performance test cases or reproduce issues.
  • Troubleshoot performance-related issues in coordination with system engineers, firmware developers, and integration teams.
  • Guide test executors in performing validation of new and existing cellular features.
  • Analyze and debug cellular device performance issues to work with firmware and systems design teams on resolutions.
  • Verify that overall UE performance meets expectations through rigorous testing and analysis.

What we're looking for

  • Minimum requirement of a bachelor's degree.
  • Knowledge of 4G/5G physical layer, protocol stack, and procedures.
  • Knowledge of 4G/5G development, system engineering, and device performance verification.
  • Knowledge of investigating and troubleshooting cellular device performance issues.
  • Understanding of software engineering principles and core computer science fundamentals.
  • Ability to script or program in languages such as Python, C/C++.
  • Experience and knowledge of multiple 4G/5G signaling and physical layer test equipment (Keysight/Anritsu/R&S) along with their automation interfaces.
  • Master's or PhD degree in wireless communication or electrical engineering (preferred).
