Are you interested in work that challenges you, expands your thinking, and provides innovative solutions for future problems while driving your growth as a recognized technical leader in the cellular industry? Apple's RF Transmitter Systems Engineering team is looking for a hard-working, dedicated individual who is eager to break technical boundaries and change the way things are done. Our best-in-class team is shaping the mobile market with disruptive RF innovations while taking full responsibility for execution and commitments to schedule and quality.

Join our team of leading experts in the cellular RF industry and deliver differentiating transmit architectures and solutions for Apple's wireless products that build amazing value for our customers!

In this role, you will be part of an industry-leading RF Transmitter Systems Engineering team. You will work closely with architecture and systems engineering teams, RF design teams, and SW teams to assess, specify, and drive transmitter concepts with a focus on innovative performance and uncompromised quality as the baseline for differentiating products.

• Translate system-level and performance requirements into requirements for the TX line-up and TX features, including RF control/algorithm specifications for RFICs and system firmware.
• Understand and specify RF algorithms (e.g., power control, calibration) and define the RF control infrastructure, including compute resources, interfaces, memory, and timing constraints.
• Lead HW/SW partitioning of RF algorithms (control functionality), ensuring optimal trade-offs between flexibility, latency, and power, and provide specifications as input for HW and SW development.
• Perform simulations (e.g., MATLAB, Python, C++) for performance analysis.
• Identify and analyze critical requirements and provide deep-dive assessments of system performance impact, timelines, and risks.
• Drive the alignment of requirements, design targets, and design trade-offs with other teams such as HW design and SW engineering.

• BS and 3+ years of relevant industry experience required.
• Strong analytical skills and the ability to collaborate and communicate across multicultural, global teams.
• Understanding of Cellular Radio/3
  
  GPP Standards (LTE, 5G /2) with a focus on system use cases.
• Experience with HW and SW co-design and clear understanding of trade-offs between digital HW and firmware implementations.
• Background in digital signal processing.
• Proficiency and practical experience in Python and MATLAB.
• Understanding of how to translate top-level requirements into specifications for transceiver building blocks, including dimensioning digital control systems for RF applications (CPU, memory, buses, real-time constraints).

• PhD in Electrical Engineering or a related field, or 5+ years of proven experience in RF, including cellular transmit architectures.
• Familiarity with cellular modem architectures.
• Experience applying Artificial Intelligence (AI) or Machine Learning (ML) to improve multi-objective optimizations.
• Knowledge of RF circuit impairments and experience modeling their system-level impact.
• Expertise in transmitter system-level concepts and control procedures like power control, digital pre-distortion, and envelope tracking.
• Understanding of SoC integration constraints and multi-chip RF architectures.
