Wireless Systems and Algorithm Design Engineer
Sunnyvale, California, United States Would you like to join Apple’s growing wireless silicon development team? Our wireless SOC organization is responsible for all aspects of wireless silicon development, addressing challenges from complex usages to demanding performances and reliabilities to enable emerging wireless applications and products. Our goal is to devise novel architectures and protocols, integrated systems, and algorithms employing advanced technologies to introduce innovative products that enhance our lives. In this technical role, you will be at the center of our silicon design and bring-up group, responsible for the wireless system design of our innovative wireless SoC products. You will play a significant role in developing the next generations of wireless communication systems for enhanced performance and reliability, creating novel algorithms, protocols, and architectures. You will participate in cross-functional task forces, including RF/analog, HW, SW, platform designers, and architects. This role encompasses wide responsibilities in implementation, verification, validation, and bringing up our SoC products to production quality for our customers! Description In this role, you will demonstrate strong analytical skills, innovative thinking, and fundamental knowledge to design creative algorithms, innovative architectures, and protocols to resolve challenges and develop best-in-class solutions in terms of performance, power, and area. You will collaborate closely with HW digital designers, RF/analog designers, and SW teams to define and specify the wireless systems. Core Responsibilities: Design and simulate innovative wireless communication systems to enable emerging applications and wireless system products. Implement system models and investigate innovative algorithms for performance enhancements, design and validate them to allow performance sign-off and enable RTL development. Implement system models for the wireless communication system, addressing RF/circuit impairments. Design methods/algorithms to alleviate those impairments using calibration, pre-equalization, canceller, and/or pre-distortion techniques. Define control procedures of the physical layer hardware modules to achieve robust and optimal performance of the Modem in congested radio environments with co-existing wireless communication systems. Work with digital designers to realize these methods with power and area-efficient digital implementations. Work with firmware designers to realize these methods with high-efficiency software implementation, possibly with hardware acceleration. Bring up, test, characterize, and optimize real silicon in the lab. Minimum Qualifications: BS and 5+ years of relevant experience required. Extensive experience in designing and developing physical layer core algorithms, such as MIMO signal estimation and detection, channel estimation, equalization, coding theory, beamforming, timing recovery, frequency synchronization, automatic gain control, etc. Track record in applying innovative signal processing, communication theory, and information theory techniques to resolve challenging problems in physical layer design for modern wireless communication systems. Deep understanding of communication theory, information theory, and signal processing related algorithms design. Strong analytical capability to develop best-in-class solutions in terms of performance, power, and area. Proficiency in C/C++ and Matlab for algorithm development, modeling, and simulation of the physical layer. Knowledge of existing protocols: 5G/LTE/WCDMA/GSM, 802.11a/b/g/n/ac/ax/be, 802.11ad/ay, or Bluetooth/BLE. Preferred Qualifications: MS and PhD preferred. Deep understanding of components/modules comprising wireless communication systems, including possible impairments and corresponding calibration and impairment reduction methods/algorithms. Algorithm development experience with hardware and firmware-friendly designs. Experience in modem architecture, microprocessor architecture, and hardware/software control. Experience in low-power algorithm design for power-critical applications. Experience with multi-radio coexistence management. Experience and knowledge of High-Level Synthesis (HLS), silicon prototyping, emulation systems, and virtual platforms. Experience in bringing up real silicon in the lab and efficiently using lab equipment (such as spectrum analyzers, signal generators, power meters, etc.). Additional Requirements: At Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $143,100 and $264,200, and your base pay will depend on your skills, qualifications, experience, and location. Apple employees also have the opportunity to become shareholders through participation in Apple’s discretionary employee stock programs. Employees are eligible for discretionary restricted stock unit awards and can purchase Apple stock at a discount through the Employee Stock Purchase Plan. You’ll also receive benefits including comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and reimbursement for certain educational expenses related to advancing your career at Apple. Apple is an equal opportunity employer committed to inclusion and diversity. We take affirmative action to ensure equal opportunity for all applicants without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, Veteran status, or other legally protected characteristics.
