Role Number: 200643872-3956 Summary Do you have a passion for invention and self-challenge? Do you thrive on pushing the limits of whatu2019s considered feasible. As part of a world class modem team, youu2019ll craft sophisticated groundbreaking embedded firmware that deliver more performance in our products than ever before. Youu2019ll work across fields to transform improved hardware elements into a single, integrated design. Join us, and youu2019ll help us innovate new cellular technologies that continually outperform the previous iterations By collaborating with other product development groups across Apple, youu2019ll push the industry boundaries of what wireless systems can do and improve the product experience for our customers across the world. Do you want to have an impact on every single Apple product?Our Global Navigation Satellite Systems (GNSS) team is part of Apple's wireless SOC team. We are a vertically integrated engineering team spanning RF, mixed signal analog design, systems engineering, Design Verification, RTL design, firmware and software engineering, Test, and Validation.As a GNSS Systems Validation Engineer, you will be a key member of Appleu2019s cellular team, driving cellular development for our next generation wireless products used by millions. Come to Apple and do your life's best work Description In this role, you will be part of the GNSS RF Systems team and play a key role in system level investigation, integration, and validation of GNSS SoC IP from early bring up through product launch in Apple devices. As a hands-on technical contributor, you will lead lab-based system level analysis, implement RF standalone calibrations, and drive validation and characterization of GNSS system-level and RF performance. You will collaborate closely with cross functional partners including RF design, algorithms, digital, firmware, software and platform teams to ensure robust integration and best in class GNSS performance across Apple platforms. Minimum Qualifications + BS and 3 + years of relevant industry experience. + Strong RF fundamentals with hands-on experience in wireless system design, integration, and lab validation. + Hands-on experience with RF measurements, including NF, IP3, phase noise, lock time, CN0, SNR, and sensitivity. + Proficiency with RF test equipment, such as network analyzers, spectrum analyzers, and vector signal generators. + Strong hands-on experience with test automation infrastructure and Python scripting. Preferred Qualifications + 5+ years of experience in wireless/RF system-level test development, SoC bring-up, debugging, and performance characterization. + Hands-on experience testing, debugging, and characterizing RF/Wireless SoC IP, including receivers, PLLs, amplifiers, ADCs, crystal oscillators, and PMUs. + Experience with RF system simulation environments, such as SystemVue, MATLAB, or Verilog. + Strong system-level intuition, including link budget analysis, receiver de-sense, and multi-radio coexistence. + Experience working on SoC system integration across hardware and software boundaries is a plus. + MS or PhD in Electrical or Computer Engineering is a plus. + Strong verbal and written communication skills. + Prior GNSS/GPS experience is a plus.
