Modem System Test Engineer - 6G/5G Data and Networking

We are seeking a motivated engineer to join the Modem System Test (MST) team in San Diego. In this role, you will contribute to building and validating end-to-end data features, protocols, and system performance across mobile, automotive, IoT, broadband platforms supporting 6G/5G modem, WiFi 7/8, ethernet and related data technologies.

You will work across layers of the protocol stack and collaborate closely with cross-functional Software, Systems and Hardware teams to ensure high-quality product readiness for global deployment.

The ideal candidate is curious about emerging technologies, eager to learn, and comfortable working in a collaborative technical environment. Strong communication and interpersonal skills are essential, along with a proactive, hands-on approach to testing and lab-based work.

You will be responsible for validating end-to-end functionality and system level performance for modem networking and data protocol features. Core responsibilities include:

* Develop and execute system-level test strategies, methodologies, and test plans for data features and use cases.

* Define key data performance indicators and evaluate system performance, including CPU/NPU performance towards close-end Edge-AI models, and optimize based on data from conducted, radiated, and live 6G/5G network testing.

* Analyze 3GPP specifications, carrier requirements and customer specifications, translating them into robust validation scenarios and test coverage.

* Perform log analysis, debugging, and root cause investigation of failures across lab and field environments.

* Support feature integration, certification, and commercialization of global products.

Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.

* Strong understanding of wireline, Ethernet, and wireless data protocols, including RLP, PPP, TCP/UDP, IPv4/IPv6, DHCP, DNS, NAT, 464XLAT, VLAN, and 802.11ac/ax/ad.

* Knowledge of IP telephony and multimedia protocols such as SIP/SDP, RTP, IMS, and related network security concepts including IPSec, EAP, TLS, and WPA2.

* Familiarity with software engineering fundamentals, including data structures, embedded operating systems, object-oriented programming, and core algorithms.

* Exposure to air-interface performance analysis, TCP/IP analysis, packet tracing tools, protocol debugging, and system optimization.

* Programming or scripting experience in one or more languages such as C, C++, Java, Python, or shell scripting on UNIX/Linux/Windows platforms.

* Knowledge of AI/ML concepts and their application to digital communications is a plus.
