RF Hardware Engineer - Multi-Radio Coexistence

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.
