As a WSoC integration and validation engineer, you will be responsible for the integration and optimization of physical layer (PHY) components in wireless communication systems. Your role will involve chip-level bring-up and Digital Signal Processing (DSP) implementation, collaborating with cross-functional teams to ensure seamless performance, compliance, and reliability of wireless connectivity solutions.
- Design, integrate and validate PHY layer components for wireless communication protocols (e.g., Bluetooth, Zigbee, UWB, etc.).- Implement and optimize DSP algorithms for signal modulation, demodulation, filtering, and error correction to enhance wireless performance.- Conduct FPGA and chip-level bring-up, including power-on testing, debug, and validation of PHY interfaces, PHY/RF/MAC functionalities and performance.- Troubleshoot and resolve integration issues at the chip level, identifying root causes and implementing solutions.- Design, execute and automate directed PHY/MAC testing scripts, which control and setup RF test equipment and RF chips.- Validate and characterize algorithms on real silicon alongside RTL, PHY, RF, MAC, and board designers.- Bring-up and take to production state-of-the-art physical layer wireless communication system algorithms for different wireless connectivity applications.- Develop and implement test plans; collect and analyze test result; identify, root-cause, and debug issues.
- BS with 3+ years relevant experience required.
- Proven experience in wireless communications, with a strong focus on PHY layer design and integration.
- Solid understanding of DSP concepts and experience with implementing DSP algorithms in real-time systems.
- Experience with chip-level bring-up, including familiarity with tools and techniques for hardware debugging.
- Experience with PHY/RF/MAC Verification.
- Experience of RF parametric testing such as EVM, ACPR, Rx sensitivity, blocker testing, etc.
- Experience with lab equipment such as network analyzer, spectrum analyzer, oscilloscopes, DMM’s etc.
- Python programming is highly desirable.
- Knowledge of wireless protocols such as Bluetooth, WLAN, UWB or others
- Verification skills in problem solving, constrained random testing, and debugging.
