TL;DR · System Test Engineer, 5G/6G Wireless Interoperability

As a System Test Engineer, 5G/6G Wireless Interoperability - Wireless Technologies and Ecosystems, you will join the Wireless Technologies team to ensure seamless connectivity across global networks. You will design and execute system-level interoperability test plans for 5G NR Sub-6 and FR2/mmWave standards, as well as emerging 6G technologies. Your daily work involves analyzing 3GPP protocol stacks, identifying failure modes, and performing root cause analysis on complex wireless issues. You will build automated test frameworks and AI/ML-assisted diagnostic tools to accelerate coverage. Key skills include proficiency in Python, shell scripting, and experience with network emulators and protocol analyzers. You will collaborate with silicon, software, and RF teams to validate device features against 3GPP specifications and reproduce field-reported issues in controlled lab environments.

What you'll do

  • Design and execute system-level interoperability test plans for 5G NR and emerging 6G technologies.
  • Analyze 3GPP protocol stacks and physical layer behavior to perform root cause analysis on wireless issues.
  • Build and maintain automated test frameworks and AI/ML-assisted diagnostic tools to increase test coverage.
  • Partner with carrier and chipset partners to define test scenarios and reproduce field-reported issues.
  • Validate new device features against evolving 3GPP specifications with hardware, software, and RF teams.
  • Triage, document, and track technical defects to drive issues to resolution with engineering teams.
  • Develop internal test infrastructure, signal analysis pipelines, and reporting dashboards.
  • Monitor 3GPP Release roadmaps to proactively identify and address testing gaps as standards evolve.

What we're looking for

  • Master's degree in Electrical Engineering, Computer Engineering, Telecommunications, or a related field.
  • 3+ years of hands-on experience in wireless system testing, interoperability testing, or protocol validation.
  • Deep knowledge of 3GPP standards including 5G NR physical layer (FR1 and FR2/mmWave), RRC, NAS, and related protocols.
  • Proficiency in scripting and automation using Python, shell, or similar for test development and result analysis.
  • Experience with AI/ML tools for test data analysis, anomaly detection, or tool development.
  • Familiarity with lab test equipment such as network emulators, protocol analyzers, and signal analyzers.
  • Experience with 6G research concepts, IMT-2030 frameworks, or pre-standard wireless technologies (preferred).
  • Knowledge of 5G core network architecture, network slicing, and SA/NSA deployment modes (preferred).
