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? As a member of our dynamic group, you will have the unique and rewarding opportunity to shape upcoming products that will delight and inspire millions of Apple’s customers every day. Our RF Systems Engineering team is looking for a passionate, self-motivated individual to work on overall system performance of multi-radio coexistence for various wireless technologies (e.g., Cellular, Wi-Fi, BT, GPS, NFC).
You will be responsible for assessing multi-radio coexistence performance across Apple's wireless ecosystem. This role involves hands-on hardware engineering, cross-functional collaboration, and data-driven validation to ensure seamless coexistence across a diverse range of radio technologies. You will work closely with RF Test Engineers, chipset teams, and cross-functional partners to identify, debug, and resolve coexistence challenges — from early design stages through final
- Performing HW failure analysis at the RF/wireless system level to identify low-margin or failing behaviors, leveraging hands-on experimental hardware modifications.
- Proposing design and process changes to address multi-radio coexistence issues, considering design constraints and aligning with cross-functional partners on trade-offs and implementation paths.
- Reviewing designs and signing off on releases of PCB layouts, flex layouts, system-level grounding, shielding, and related components.
- Executing validation and characterization test plans to meet multi-radio coexistence performance targets.
- Tracking validation status, analyzing results, and communicating actionable insights from data.
- Evaluating multi-functional change requests, updating characterization plans as needed, and surfacing any emerging issues.
- Collaborating with RF Test Engineers on device bring-up, test setups, and test procedures for multi-radio coexistence validation.
- Performing experiments using hardware mock-ups, system prototypes, and experimental setups.
- Partnering with cross-functional teams on circuit-level and system-level simulations to identify risk areas and drive root cause analysis.
- Designing performance-based test setups and benchmarks to evaluate multi-radio coexistence across a range of coexistence scenarios.
- Bachelor’s degree in electrical engineering with 10+ years relevant work experience.
- Experience with at least one radio technology: Cellular, GPS, Bluetooth, Wi-Fi, Thread, NFC, or UWB.
- Knowledge of RF component characteristics and proficiency with lab equipment including spectrum analyzers, network analyzers, signal generators, and oscilloscopes.
- Knowledge of wireless architectures including front-end design, antenna sharing, and link budget line-up.
- Ability to travel domestically and internationally up to 20%.
- Strong written and verbal communication skills.
- Solid understanding of fundamental antenna theory.
- Master’s degree in electrical engineering with 10+ years of relevant work experience.
- Proven understanding of RF hardware and best practices for system-level grounding, shielding, isolation, and electromagnetic interference mitigation.
- Experience in performing hands-on disassembly and system-level debug at the module, reference board, or system level.
- Experience in debugging and optimizing conducted or radiated radio systems.
- Experience in antenna design and EM simulation.
