Imagine what you could do here. At Apple, new ideas have a way of becoming extraordinary products, services, and customer experiences very quickly. Bring passion and dedication to your job and there’s no telling what you could accomplish. Dynamic, smart people and inspiring, innovative technologies are the norm here. Join us to help deliver the next groundbreaking Apple product. The Wireless Communication group at Apple is a high energy, results-oriented team. We are looking for highly motivated and committed engineers to join our exciting team of innovators. In this role, you will be a key member of the cellular system engineering team working on physical-layer development, with a focus on millimeter-wave beam management.

DESCRIPTION

In this technical role, you will be responsible for scoping and development of millimeter-wave beam management physical-layer features in 5G-NR as part of cellular system engineering team working on state-of-the-art wireless products. Core responsibilities: • Define features and requirements, as proprietary initiative or based on 3GPP standards; • Explore and propose concepts & algorithms, identifying performance trade-offs; • Develop and simulate models to ensure robust functionality & performance; • Work with architects, upper-layer designers, and RF engineers to optimize architectural partition, control/message flows, and timelines; • Collaborate with firmware and software developers for power- & area-efficient realization; and • Drive end-to-end verification and resolve issues for commercialization.

• Solid foundations in signal processing and communication theory, such as OFDMA, multi-antenna techniques, signal/parameter estimation and detection.
• Strong analytical and problem-solving skills.
• Experience with physical-layer architecture and porting concepts to HW/FW-ready designs.
• Experience with Matlab, C/C++ and/or Python for concept development, modeling, and link-level simulation.
• Strong teamwork spirit, respectful of diverse viewpoints, open to adapting ideas based on technical debates, sharing credit, focused on getting the best out of collective thoughts for achieving common goals.

• Flexibility and agility to adapt to fast-paced collaborative environment.Strong sense of accountability for collective success, sensitivity to the needs of projects/team and ability to proactively identify white spaces & steer stakeholders toward closure.

PREFERRED QUALIFICATIONS

• Experience in wireless beamforming research and development, including collaboration with HW/FW/SW towards product commercialization.
• Knowledge of cellular communication standards, in particular 5G-NR RAN1/RAN4, including PHY/MAC/RRC procedures.
• Familiarity with cellular user equipment (UE) baseband modem architecture, including interfaces among subsystems.
• Familiarity with RF, phased arrays, AGC, and inter-chip communication & control.
• Experience in chip bring-up and conducted/over-the-air lab/field verifications.
• M.S. in Electrical Engineering or Computer Science with applicable years of working experience or Ph.D. in relevant field. Candidates with more experience will be considered for suitably senior positions.
