At Apple, new ideas have a way of becoming extraordinary products, services, and customer experiences — fast. 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.

Description

We're looking for a Wireless 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, and silicon validation — 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.

Minimum Qualifications

BS and a minimum of 20 years relevant industry experience
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

MS or PhD in Electrical Engineering, Communications, or Signal Processing, with 20+ years of relevant industry experience is preferred.
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 is a plus.
