About the role

Position focused on integration, validation, and optimization of PHY layer components for wireless communication systems, including chip-level bring-up, DSP implementation, and cross-functional collaboration to ensure performance, compliance, and reliability of wireless solutions.

Responsibilities

  • 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.

Qualifications

  • BS and a minimum of 10 years relevant industry experience.
  • 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.
  • Experience with lab equipment such as network analyzer, spectrum analyzer, oscilloscopes, DMM’s.
  • Python programming is highly desirable.
  • Knowledge of wireless protocols such as Bluetooth, WLAN, UWB.
  • Verification skills in problem solving, constrained random testing, and debugging.
