Job summary

Apple Inc. in Sunnyvale seeks a Wireless Control Systems Engineer to own end-to-end lifecycle of cellular modem systems, from feature design through silicon bring-up for 6G/5G and 4G 3GPP features with AI/ML‑enhanced control strategies.

Collaborate with SoC, PHY, and L1 SW teams to meet full-stack requirements, optimize performance and power, and drive real-world deployment benefits across Apple products.

Qualifications

• BS in Electrical Engineering, Computer Engineering, or related field, with 10+ years of relevant industry experience in Layer 1 control design.
• Strong knowledge of cellular communication standards: 6G (emerging), 5G NR, 4G LTE — RAN1 3GPP.
• Deep expertise in communication system theory and signal processing: LDPC, Polar, and Turbo coding; signal estimation and detection; RF impairment estimation and correction; channel estimation; OFDM; MIMO detection; waveform generation and up‑sampling.
• Proficiency in MATLAB, C/C++, and/or Python for algorithm development, fixed/floating‑point modeling, and link‑level simulation.
• Experience leveraging Generative AI and LLM‑based tools to accelerate engineering workflows — e.g., algorithm prototyping, code generation, simulation analysis, or technical documentation

Responsibilities

• Define & architect system-level features and requirements for next-generation cellular modems, with a focus on 6G evolution and advanced PHY/L1 capabilities.
• Own the E2E system view — connect 3GPP standard requirements, algorithm design trade‑offs, HW/FW architecture constraints, and product-level targets into cohesive, leading‑edge control solutions.
• Design Control algorithms (Traditional or AI/ML based) for the physical layer, across layers and L1/RF control to optimize performance/power.
• Construct interfaces and Message flows for wireless features across layers.
• Model & simulate algorithms in floating-point and fixed‑point using MATLAB, C/C++, and/or Python, and validate, through link‑level simulation or correlating with data collected from field and real deployments.
• Optimize for user experience by driving performance and power efficiency improvements across the wireless stack — translating system-level insights into tangible gains in throughput, latency, battery life, and connectivity reliability based on real world deployments. Use the available information from deployments and statistics from field to fine tune the performance.
