What is 5G protocol testing?

A 5G Protocol Testing job involves verifying and validating the functionality, performance, and compliance of 5G network protocols. It includes testing layers such as RRC, NAS, and PHY/MAC to ensure interoperability between network elements and devices. Engineers use test tools like Wireshark, UE simulators, and protocol analyzers to troubleshoot and optimize network performance. This role requires knowledge of 3GPP specifications, scripting, and automation to execute test cases and analyze log files.

What does a typical day look like for someone working in 5G protocol testing?

A typical day in 5G Protocol Testing involves preparing and executing test cases, analyzing logs and test results, identifying protocol-related issues, and collaborating closely with development and network teams. You may spend time using specialized tools to simulate network scenarios, document defects, and participate in meetings to discuss project status or troubleshooting efforts. Testers often work in a dynamic environment that may require adapting to the latest 3GPP standards or technology updates. This role offers the opportunity to build expertise in advanced telecommunications and is an excellent stepping stone for career growth into senior testing, integration, or network engineering roles.

What are the key skills and qualifications needed to thrive in 5G protocol testing, and why are they important?

To excel in 5G Protocol Testing, you need a solid background in wireless communication standards, protocol stack knowledge, and hands-on experience with telecom testing tools, often supported by a degree in engineering or a related field. Familiarity with tools such as Wireshark, UE simulators, protocol analyzers, and industry certifications like ISTQB or similar are commonly expected. Strong analytical thinking, problem-solving skills, and effective communication enable testers to work efficiently within cross-functional teams. These capabilities are vital for ensuring network reliability, troubleshooting complex protocol issues, and delivering high-quality 5G products.

We are partnering with mobile network operators globally to provide direct-to-cell service, extending coverage to billions of existing cellular devices. Starlink Mobile was designed to connect the unconnected, and this new product will greatly expand that mission by extending coverage to billions of existing cellular devices. Applications include connecting hikers in national parks, emergency responders, rural communities, remote sensors, and people in emergency situations. 

As a Sr. RAN Software Engineer on the Starlink Mobile program, you will lead the validation and optimization of the 4G/5G RAN software protocol stack. This role requires strong software engineering skills to build scalable test automation frameworks and work directly with other software developers to triage and resolve complex 4G/5G protocol stack software issues.  

RESPONSIBILITIES: 

  • Lead the design, development, and maintenance of CI/CD test automation frameworks for eNB/gNB feature validation, including functional, performance, interoperability, and regression testing 
  • Analyze UE and eNB/gNB logs to debug and root-cause RAN issues, and collaborate with developers to resolves issues and drive feature improvements 
  • Build software tools and data pipelines to analyze RAN performance and optimize eNB/gNB parameters to improve network KPIs 
  • Manage and prioritize network issues while collaborating closely with development teams to drive resolution 
  • Troubleshoot and maintain RAN lab infrastructure in collaboration with partner teams 

BASIC QUALIFICATIONS: 

  • Bachelor's degree in a STEM discipline
