Full Job Description
We're looking for a Wireless Control Systems Engineer to join our cellular systems engineering team as we define and build the next generation of cellular technology. This is a rare opportunity to shape the future of wireless communication at a company that ships at global scale as we transition towards 6G. In this role, you'll bring an end-to-end view of wireless systems - spanning 3GPP standards, algorithm design, hardware architecture, timing requirement, interfaces, message flows - to deliver leading-edge performance and power optimizations that directly improve the user experience across Apple products. If you thrive at the intersection of deep technical theory and hands-on bring-up - and you're excited about pushing beyond 5G into the 6G era - we want to hear from you. Description As a Wireless Control Systems Engineer, you will own the end-to-end lifecycle of cellular modem systems - from feature design through silicon bring-up and productization for 6G/5G and 4G 3GPP features and proprietary enhancements to improve user experience. Collaborate cross-functionally with SoC, PHY, PHY HW, PHY FW, and L1 SW teams to ensure end-to-end system requirements are met across the full stack. Minimum Qualifications BS in Electrical Engineering, Computer Engineering, or a 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 - particularly RAN1 3GPP. Deep expertise in communication system theory and signal processing: LDPC, Polar, and Turbo coding; signal estimation and detection; AGC; 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 Preferred Qualifications Experience in Layer-1 Control Design. Experience in low-power algorithm design for power-constrained mobile platforms. Experience in end-to-end timeline analysis for latency-critical PHY processing chains. Hands-on silicon bring-up experience, including use of lab equipment: protocol testers, spectrum analyzers, signal generators, power meters. Strong mathematical foundations: linear algebra, stochastic processes, detection & estimation theory. Familiarity with 3GPP standardization processes, RAN2, RAN4 topics and emerging 6G study items (e.g., AI/ML for air interface, sub-THz bands, joint communication and sensing, reconfigurable intelligent surfaces). Track record of published research or patents in wireless communications.

About Apple

Apple is a corporation that designs, manufactures, and markets mobile communication and media devices, personal computers, portable digital music players, and sells a variety of related software, services, peripherals, networking solutions, and third-party digital content and applications. Apple provides many products and services, including iPhone; iPad; iPod; Mac; Apple TV; a portfolio of consumer and professional software applications; the iOS and OS X operating systems; iCloud; and accessories, service, and support offerings. It sells its products worldwide through its retail stores, online stores, direct sales force and third-party cellular network carriers, wholesalers, retailers, and value-added resellers to the consumer and also sells third-party iPhone, iPad, Mac and iPod compatible products, including application software and accessories through its online and retail stores. Introduced in 1984, the Macintosh was the first widely sold personal computer with a graphical user interface (GUI). That feature and others such as an improved floppy drive design and a low-cost hard drive that made data retrieval faster helped Apple cultivate a reputation for innovation. Apple was named as the most admired company in the United States in 2008 and in the world from 2008 to 2012 by the Fortune magazine. The company was founded by Steven Paul Jobs, Steve Wozniak, and Ronald Gerald Wayne on April 1, 1976, and is headquartered in Cupertino, California.
