6G Cellular Modem Systems Engineer

Role Number: 200688806-3543

Summary

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.

We're looking for a Cellular Modem 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, feature definition and planning, design, hardware and software architecture and partitioning — to deliver leading-edge performance and power optimizations and features 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 Cellular Systems Engineer, you will own the end-to-end lifecycle of cellular modem systems — from feature set and capability definition that improve cellular user experience of our products to concept work, algorithm design through silicon bring-up and productization. In this role you are expected to Collaborate cross-functionally with eco-system teams, 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.

• Strong knowledge of cellular communication standards and associated feature sets: 6G (emerging), 5G NR, 4G LTE — particularly RAN1 3GPP.

• 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-1/2 control design of cellular systems.

• Experience in low-power algorithm design for power-constrained mobile platforms.

• Experience in end-to-end timeline analysis for latency-critical PHY processing chains.

• 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, joint communication and sensing, reconfigurable intelligent surfaces).

• Track record of published research or patents in wireless communications is a plus.
