About The Position

Join the Connectivity, Cellular, and Satellite team to help develop the next generation of Multi-Radio Coexistence (Coex). The role focuses on architecting and optimizing intelligent real-time scheduling algorithms that enable concurrent wireless technologies—including Wi-Fi, Bluetooth, Satellite, Thread, Cellular, and next-generation protocols—to operate seamlessly in shared spectrum.

As a Multi-Radio Coex Software QA Engineer, you will help shape wireless software and systems from concept to release. You will partner with development and systems teams across Bluetooth, Wi-Fi, Cellular, Thread, and Satellite to address coexistence challenges, prioritize concurrent traffic, and reduce mutual RF interference. The work extends beyond traditional testing: you will drive architectural improvements, identify test-coverage gaps, and design validation workflows, including developing and maintaining AI-based automation frameworks for complex, real-world multi-radio scenarios.

Requirements

• Master’s or Ph.D. degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent practical experience.
• 2 to 5 years of experience in Wireless Systems Engineering or Software QA.
• In-depth understanding of Multi-Radio Coexistence scheduling, real-time priority arbitration, and concurrent wireless behavior across technologies such as Bluetooth, Wi-Fi, Cellular, Thread, and Satellite.
• Hands-on experience testing and qualifying mobile devices and cellular/connectivity technologies under concurrent traffic and high-interference conditions.
• Deep understanding of Software QA methodologies, test-plan creation, bug triage, and root-cause analysis.
• Proficiency in functional testing and willingness to engage in both manual exploration and automation.
• Proven track record designing, building, and maintaining robust test automation frameworks.
• Strong proficiency in modern scripting or compiled languages such as Python or Swift.
• Ability to investigate complex multi-radio failures, prioritize by customer impact, and propose clear technical resolutions.
• Excellent communication skills and ability to explain technical concepts to hardware, software, firmware, and performance teams.
• Ability to work under tight schedules and deliver reliable, high-quality results on time.

Nice To Haves

• Experience leading technical initiatives and mentoring team members in a fast-paced environment.
• Deep debugging and root-cause analysis skills in complex wireless communications environments, including use of protocol analyzers, over-the-air sniffer captures, and system trace logs.
• Hands-on experience developing, integrating, or deploying Generative AI and machine-learning tools to improve test automation and data analysis.
• Ability to design, build, and maintain internal testing tools and diagnostic utilities that improve team-wide testing efficiency.
• Comfort managing concurrent projects across engineering domains such as Bluetooth, Wi-Fi, Cellular, and Satellite while maintaining attention to detail.
• Strong interpersonal, communication, and technical documentation skills, including the ability to influence cross-functional roadmaps.
• Self-driven problem-solving skills and ability to work independently and with multidisciplinary teams.

Responsibilities

• Partner with development and systems teams across Bluetooth, Wi-Fi, Cellular, Thread, and Satellite to address coexistence challenges.
• Help prioritize concurrent wireless traffic and eliminate mutual RF interference.
• Drive architectural enhancements to wireless software and systems.
• Identify gaps in test coverage and design next-generation validation workflows.
• Develop and maintain AI-based test automation frameworks for complex, real-world multi-radio scenarios.
• Create test plans, conduct functional testing, triage bugs, and perform root-cause analysis.
• Investigate complex multi-radio failures, prioritize them by customer impact, and propose technical resolutions.
• Deliver reliable, high-quality results on schedule.
