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, sensible people and inspiring, innovative technologies are the norm here. Join us to help deliver the next groundbreaking Apple product. Do you love working on challenges that no one has solved yet? Are you ready to join a team redefining hardware technology? 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 beam management in higher-frequency bands.

### Description

As a Cellular Systems Engineer, you will be responsible for scoping, development, pre- and post-silicon bring up, and end-to-end validation of physical-layer beam management features in 5G and 6G. This includes defining requirements and concepts, mapping them to HW/FW architecture, and validating the control flows and algorithms via simulations and emulations.

### 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/antenna engineers to optimize architectural partition, control/message flows, and timelines;
- Collaborate with firmware and software developers for power- & area-efficient realization; and
- Drive pre- and post-silicon verification, validation, and bring-up of silicon, to support commercialization.

### Minimum Qualifications

- 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 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

- In addition, candidates with strengths in one or more of the following areas will be given preference.
- M.S. in Electrical Engineering or Computer Science with 3+ years of working experience or Ph.D. in relevant field. Candidates with more experience will be considered for suitably senior positions.
- Experience in wireless beamforming research and development, including collaboration with HW/FW/SW towards product commercialization.
- Familiarity with RF, phased arrays, AGC, and inter-chip communication & control.
- Familiarity with cellular user equipment (UE) baseband modem architecture, including interfaces among subsystems.
- Knowledge of cellular communication standards, in particular 5G and 6G RAN1/RAN4, including PHY/MAC/RRC procedures.
- Experience in chip bring-up and conducted/over-the-air lab/field verifications.
