Do you have a passion for invention and self-challenge? Do you thrive on pushing the limits of what's considered feasible?

As part of our modem development team, you'll architect sophisticated leading-edge wireless modems that deliver more performance in our products than ever before. You'll work across disciplines to transform improved hardware elements into a single, integrated design. Join us, and you'll help us innovate new wireless systems technologies that continually outperform the previous iterations. By collaborating with other product development groups across Apple, you'll push the industry boundaries of what wireless systems can do and improve the product experience for our customers across the world.

As a Modem Architect on this team, you will be responsible for architecting state of the art wireless communication systems focusing on modem power and clock architecture. This position requires someone familiar with HW architecture definition including HW-SW partitioning and optimization of the design of performance, power and area. We are looking for someone that thrives in a dynamic multi-functional organization, is not afraid to debate ideas openly, and is flexible enough to pivot on constantly evolving requirements.

Key Qualifications

  • In-depth knowledge on power, clock and reset architecture targeting power efficient modems for high data rate wireless communication systems

  • Exposure to mapping product requirements onto detailed system requirements providing basis for system architecture definition of power architecture to meet e2e power critical metric.

  • Experience in architecting SoC power and clock management sub-systems - designing DVFS, selection of PLL's and LDO's, crafting sequencers, regulators, clock generation, clock gating/reduction techniques, etc.

  • Driven multi-functional topics covering across teams with wide-ranging strengths to arrive at efficient hardware/software partitioning

  • Exposure to hardware and software architecture in SoC architecture topics - boot sequences, microprocessor, connectivity, memory and peripherals

  • Bring up real silicon in lab, able to efficiently use lab equipment (such as spectrum analyzer, signal generator, power meter, etc.).


In this technical role, you will be steering modem system power and clock architecture as part of a modem development group responsible for state-of-the-art wireless products. Architecture definition for implementation of power and clock infrastructure targeting very high data rate applications - analysis of requirements, HW-SW split, analysis of power/performance/area tradeoffs, performance simulations. Work closely with the system teams in developing the system power architecture from the product requirements. Close collaboration with digital designers to realize the architecture with power and area efficient digital implementations.

Education & Experience

MS/Ph.D degree with 5+ years experience in modem architect development.

VIEW JOBS 5/8/2020 12:00:00 AM 2020-08-06T00:00 Would you like to join Apple's growing mmW and cellular wireless design team? Our team is responsible for mmWave and cellular RF Systems Engineering with a particular emphasis on all control and interface aspects of RF Transceiver designs that transform the user experience at the product level. As a Clock Concept Architect, you will be at the center of the wireless systems engineering. Come join us and enable the heartbeat of the analog and digital functionality of RF mmW/Cellular transceivers! Key Qualifications * We value your 7+ years of relevant experience in digital/analog/mixed signal chip design, including direct expertise in clock concepts and their underlying architectures. * In-depth knowledge of chip external and internal clock structures, including generation and distribution of clock networks throughout the complete system. * Expertise with clock modelling techniques to assess critical aspects at an early project stage. Your expertise will help to balance techniques like clock gating and frequency voltage scaling to get optimal trade off in flexibility and power consumption. * Creative in defining new and adapting existing clock management concepts for Hardware and Firmware that will enable the deployment of developed concepts. * Basic knowledge of cellular radio standards (GSM, UMTS, LTE, 5GNR) to derive the relevant use cases and the proper set of requirements for the clock. * Strong analytical and interpersonal skills with an ability to thrive in a multi-functional environment. * Strong technical writing skills. Description * Work closely with RF Systems Engineers and RF design teams to assess, scope, and ultimately drive the clock net of the related chip sets to meet the challenges of next generation wireless products. • Work with implementation specialists to allow for best integration of design for testability features as well as supporting high quality coverage of verification requirements. • Coordinate stakeholders inside a wider RF community to best combine knowledge for optimal clock structures, codesigning with reset and power concept. • Seek a scalable solution that allows for fast adaptions on ever changing product environment. • Occasional travel including international may be required. Education & Experience BS or MSEE required; Ph.D. preferred. Additional Requirements * Apple is an equal opportunity employer that is committed to inclusion and diversity. We also take affirmative action to offer employment and advancement opportunities to all applicants, including minorities, women, protected veterans, and individuals with disabilities. Apple will not discriminate or retaliate against applicants who inquire about, disclose, or discuss their compensation or that of other applicants. * We will ensure that individuals with disabilities are provided reasonable accommodation to participate in the job application or interview process, to perform essential job functions, and to receive other benefits and privileges of employment.
