WSoC PHY​/MAC Validation and Integration Engineer

WSoC PHY/MAC Validation and Integration Engineer

San Francisco Bay Area, California, United States Hardware

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 set up 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 results; identify, root‑cause, and debug issues.

• 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 with 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.

• Base pay range $184,700 – $324,800 (dependent on skills, qualifications, experience, and location).
• Apple employee stock program participation and stock purchase plan options.
• Comprehensive medical and dental coverage, retirement benefits, discounted products and free services.
• Reimbursement for certain educational expenses — including tuition.
• Possibility of discretionary bonuses or commission payments and relocation assistance.
