Job description

Wireless Systems Integration Engineer, RF/PHY

At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? Do you like changing the game? We have an opportunity for a forward-thinking and unusually hardworking Wireless System Engineer. As a member of our multi-faceted Wireless Connectivity team, you will have the rare and extraordinary opportunity to craft upcoming products that will delight and encourage millions of Apple’s customers every single day.

Description

In this role, you will play a key part in the integration, bring‑up, and tuning of physical layer/RF systems for next-generation wireless SoCs - from pre‑silicon stage to product launch in Apple devices. You get to collaborate across disciplines—including PHY algorithms, RF design, digital, MAC, and firmware teams - to ensure seamless integration and best‑in‑class wireless performance.

Responsibilities

• Drive Bring‑up, integration, and performance optimization of Wi‑Fi PHY and Radio Systems for both pre‑silicon and post‑silicon stages.
• Develop and integrate PHY features and calibration algorithms such as TPC, AGC, TSSI, RSSI, and interference mitigation.
• Debug and root‑cause system performance issues across RF domains (impairments, calibration, gain control) and digital PHY processing (OFDM, synchronization, channel estimation, MIMO).
• Collaborate closely with PHY system Algorithm Engineers as well as Radio, RFIC, MAC and digital circuit designers to ensure end‑to‑end feature integration.
• Supporting the transition from lab bring‑up to robust firmware integration and product readiness.
• Characterize RF/PHY performance, and drive resolutions to ensure robust, high‑quality product delivery.

Minimum Qualifications

• BS and a minimum of 3 years relevant industry experience
• Hands on experience in wireless system design, integration, or bring‑up.
• Strong fundamentals in signal processing, communication theory, OFDM systems, radio architectures, and analog/RF impairments, with understanding of their impact on key system performance metrics.

Preferred Qualifications

• Experience, knowledge and skills on wireless system design, integration, bring up and debug of wireless PHY and RF systems on SoC platforms.
• Strong understanding of OFDM and MIMO‑based wireless systems across both baseband and RF domains, with a solid foundation in related communication theory and signal processing.
• Strong understanding of wireless transceiver architectures, RF front‑ends and related system‑level tradeoffs.
• Knowledge of analog/RF impairments (e.g., DCOC, IQ imbalance, IP2, LOFT, DPD) and their calibration flows.
• Proficiency in performance metrics such as EVM, sensitivity and impairment mitigation strategies.
• Experience working across multi‑radio coexistence environments.
• Proficiency using and understanding of the theory of operation of lab equipment such as spectrum analyzer, signal generator, power meter.
• Experience with at least one of the following - Matlab, Python, Shell scripting and/or C/C++.
• Experience with automation infrastructure development including traceability, repeatability and related tools (GIT, CI, database, reporting tools).
• Knowledge of existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be, LTE/WCDMA/GSM, or 802.11ad/ay.
• Advanced degrees - MS or PhD in Electrical Engineer, Computer Engineering or other technical disciplines
