Perform system bring-up, initial debugging, and optimization of radio designs. Assist in troubleshooting and resolving complex RF issues, including desensitization, spurious emissions, and basic EMI, using RF test equipment (Spectrum analyzer, VNA , Load Pull and callbox). Characterize key RF components (e.g., RFICs, FEMs) to ensure performance meets specifications. Develop and define new test procedures or Product Functional Specification (PFS) items to characterize the RF system performance. Test Automation & Tool Development: Develop, implement, and maintain automation scripts and tools using Python to streamline RF testing and data analysis. Contribute to the development and maintenance of test automation frameworks and support continuous integration/delivery (CI/CD) pipelines. Contribute to improving test efficiency, reducing test time, and optimizing test processes. Regulatory Compliance Support: Lead and support in-house radio pre-compliance testing efforts and manage 3rd party radio certification processes for global markets (FCC, ETSI, SRRC, MIC, etc.). Design and build test automation suites to streamline radio compliance testing conducted at 3rd party labs. Maintain an in-depth understanding of evolving radio compliance standards in various regions and global markets, proactively identifying and contributing to strategies for regulatory adherence. RF Simulation & Analysis Support: Support RF simulation efforts using tools like ADS or QUCS to analyze RF system performance. Conduct electromagnetic (EM) simulation of PCB layout-related issues using full-wave simulation solvers such as CST or HFSS. Contribute to evaluating system-level performance metrics, including basic coexistence scenarios. Support link budget analysis and basic interference studies. Manufacturing & JDM Partner Support: Provide technical support and automation for radio production activities at Contract Manufacturing (CM) and Joint Development Manufacturing (JDM) partners. Assist in on-site and remote debugging of radio-related issues during line bring-up and mass production. Contribute to the analysis of factory production line data to identify trends and assist in troubleshooting. Support the definition and optimization of manufacturing processes for radio products. Lab & Test Environment Management: Configure and troubleshoot network infrastructure within lab and test environments. Manage and maintain test setups and lab spaces, including test benches and OTA chambers. Prepare and maintain tools and equipment for compliance testing and travel. Cross-Functional Collaboration: Collaborate effectively with Hardware, Software, Manufacturing, Compliance, and other engineering teams to debug and optimize overall system performance in highly integrated environments.

EDUCATION AND EXPERIENCE REQUIREMENTS:

Master's degree (or foreign equivalent) in Electrical Engineering, Computer Engineering, Radio Frequency Engineering, or related field plus 2 years of experience in the offered position or related position.

SPECIAL REQUIREMENTS:

Must possess expertise/knowledge sufficient to adequately perform the duties of the job being offered. Expertise/knowledge may be gained through employment experience or education. Such expertise/knowledge cannot be "quantified" by "time". Required expertise/knowledge includes:

• Experience in Radio Frequency testing, integration, or product development, for Wi-Fi and Bluetooth-enabled devices in the consumer electronics industry.
• Experience with architecting, developing, and deploying robust Radio Frequency automation test frameworks in Python using libraries (Pandas and NumPy), including designing scalable, maintainable, and reusable code modules to interface with various Radio Frequency test equipment and Devices Under Test (DUTs) as well as analyzing large datasets from radio performance tests and applying statistical methods for anomaly and outlier detection.
• Data visualization skills (Matplotlib, Seaborn and Plotly) for communicating radio performance test results to stakeholders.
• Experience with Git/GitHub for version control, including using branching strategies, pull requests, code reviews, and resolving merge conflicts in collaborative development environments.
• Experience with GitHub Actions for automating Continuous Integration/Continuous Delivery pipelines supporting automated build, deployment, and validation workflows in branch and pull request stages to enable stable, reliable, and continuously updatable test solutions.
• Experience with 3rd party Radio Frequency test automation frameworks (IQFact, QDART and CMWrun) to capture comprehensive transmit and receive performance metrics, including EVM, ACLR, sensitivity, throughput, and coexistence.
• Experience with automated execution of continuous integration and delivery pipelines triggered by GitHub events, including build, deployment, and validation checks in branch and pull request workflows.
• Understanding of Radio Frequency fundamentals, including common wireless protocols (Wi-Fi and Bluetooth) for creating and validating test setups, debugging performance issues, troubleshooting connectivity issues and understanding the relationship between performance metrics and improving reliability of wireless communication systems.
• Experience with Radio Frequency test and measurement equipment, including spectrum analyzers, network analyzers, signal generators, and callboxes (CMW500) for wireless system bring-up, validation, and debugging.
• Experience with Linux environments, including navigating file structures, Secure Shell/remote device control, network tools (ping and netstat), utilizing built-in utilities (grep, vi and find), deploying Docker containers and debugging kernel logs and building kernel modules.
• Experience with global Wi-Fi and BT/BLE regulatory standards (FCC, CE, ETSI, MIC and SRRC) applied in Radio Frequency validation and performance analysis, including evaluating Tx/Rx performance, analyzing Radio Frequency metrics, and identifying compliance risks.
• Experience with applying Radio Frequency/Electromagnetic simulation tools (ADS, CST and QUCS) in Radio Frequency design validation and debugging, including modeling Radio Frequency circuits and structures, analyzing performance, identifying layout-related issues, and correlating simulation results with measurements to support root cause analysis and design optimization.
• Experience in Supporting manufacturing and debugging efforts at Contract Manufacturing (CM)/Joint Design Manufacturing (JDM) facilities, including ensuring robust and repeatable Radio Frequency test setups, deploying automated test platforms, analyzing test data, and troubleshooting Radio Frequency/system issues during builds to enable early detection of design and performance issues, improve production efficiency and yield, and ensure stable mass production.
