Apple

Come join Apple's growing wireless silicon development team. Our wireless SoC organization is responsible for all aspects of wireless silicon development, with a particular emphasis on highly energy-efficient design and new technologies that transform the user experience at the product level. All of this is driven by a world-class vertically integrated engineering team spanning RF/Analog architecture and design, Systems/PHY/MAC architecture and design, VLSI/RTL design and integration, Emulation, Design Verification, Test and Validation, and FW/SW engineering. In this role, you will help de-risk our silicon well ahead of tape-out by owning the pre-silicon emulation environment that enables the team to exercise and verify new designs early and with confidence. We are looking for a wireless PHY systems engineer for this role: your understanding of the full signal chain, from RF and PHY through MAC and firmware, will help ensure that each emulated design not only comes up but behaves as intended. Prior Palladium experience is not required, and we will help the right candidate ramp up on the platform. If you enjoy a fast-paced and challenging environment, collaborate with people across different functional areas, and thrive during crisis times, we encourage you to apply. 
Description 
This role is central to Apple's pre-silicon verification effort for wireless SoCs, centered on the Palladium emulation platform. You will be the first to bring up each newly released emulation build, and you will design and own the framework and infrastructure - register maps, initialization and boot sequences, clock and reset, and system-level configuration - that brings the emulated SoC into an operational state and enables the wider team to run their own design verification. Working at the intersection of digital design, firmware, and validation, you will own and evolve this infrastructure across successive silicon generations, while also contributing to pre-silicon emulation and lab bring-up of Bluetooth and UWB silicon.","responsibilities":"Act as the initial validation point for each released Palladium emulation build, performing early smoke and sanity testing to confirm the build is functional, correctly configured, and ready for broader team use. 
Build and own the framework and infrastructure that exercises the Palladium build - including register map definitions, initialization and boot sequences, clock and reset setup, and other system-level configuration - to bring the emulated SoC into an operational state. 
Abstract platform bring-up and configuration complexity into reusable infrastructure and tooling, enabling the rest of the team to concentrate on their own design verification rather than platform-level setup. 
Sustain, extend, and maintain this emulation infrastructure across multiple silicon generations, establishing it as a long-lived, reusable platform rather than a per-project effort. 
Support pre-silicon emulation efforts for silicon validation, including test development, debug, and performance characterization on emulation platforms. 
Bring up, test, characterize, and optimize Bluetooth and UWB silicon in the lab, ensuring robust performance across real-world operating conditions. 
Preferred Qualifications 
Master's degree with 10 years of relevant experience. 
Hands-on experience in wireless chip or modem development, with a strong systems-level understanding of cross-layer dependencies between RF, PHY, MAC, and firmware. 
Hands-on experience in Bluetooth and UWB systems design and validation. 
Digital design fundamentals and a solid understanding of SoC architecture and system-level hardware/software interaction. 
Hands-on RTL experience (Verilog/VHDL) and experience with register map and programming-model definition. 
Experience with fixed-point design, RTL vector generation, and/or High-Level Synthesis (HLS). 
Experience with pre-silicon emulation (e.g., Palladium) or FPGA prototyping, including build bring-up, debug, and performance characterization. 
Experience developing validation frameworks and infrastructure, including initialization sequences, clock and reset setup, and system-level configuration. 
Experience in lab FPGA/silicon bring-up, PHY/RF/MAC testing, and use of RF lab equipment. 
Proficiency with Python for test automation and data analysis, and experience with simulation automation, regression frameworks, or CI/CD pipelines. 
Experience collaborating with firmware and FPGA/emulation engineers to bring up, integrate, and debug hardware platforms, ensuring correct hardware/software interaction. 
Minimum Qualifications 
Bachelor's degree with 10 years of relevant experience. 
Solid foundation in Digital Signal Processing (DSP) and wireless communications, with working knowledge of PHY and MAC layer concepts. 
Hands-on software programming skills for system modeling, simulation, and test, with proficiency in MATLAB and C/C++. 
Familiarity with analog/RF impairments common in wireless systems (e.g., phase noise, IQ imbalance, nonlinearity). 
Experience with or knowledge of wireless standards such as Bluetooth, Ultra-Wideband (UWB), or other wireless protocols. 
Experience collecting, processing, and visualizing large-scale simulation and test datasets, including performance metrics such as measurement accuracy, latency, and throughput. 
Strong communication skills, both written and oral, with the ability to work effectively across cross-functional teams. 
Pay &amp; Benefits 
At Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $184,700 and $324,800, and your base pay will depend on your skills, qualifications, experience, and location. 
Apple employees also have the opportunity to become an Apple shareholder through participation in Apple's discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple's Employee Stock Purchase Plan. You'll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses - including tuition. Additionally, this role might be eligible for discretionary bonuses or commission payments as well as relocation. Learn more about Apple Benefits
