RF Hardware Engineer - Multi-Radio Coexistence

You will be responsible for assessing platform-level multi-radio coexistence performance, including:

- Performing HW failure analysis at the RF/wireless system level to understand low margin or failing behaviors making use of hands-on experimental modifications to hardware.
- Proposing design and process changes for multi-radio coexistence issues considering design constraints and align with cross-functional partners on trade-offs and implementation path.
- Reviewing designs and sign-off on releases of PCB layouts, flex layouts, system level groundings, shielding.
- Execution of validation & characterization test plans to meet multi-radio coexistence performance targets.
- Tracking validation status, analyze results and communicate insight from data.
- Evaluating multi-functional change requests and update characterization plans as needed, highlight any issues.
- Working with RF Test Engineers to bring-up device-under-test, setups and test procedures for multi-radio coexistence validation.
- Performing simple experiments using hardware mock-ups, system prototypes and experimental setups.
- Collaborating with cross-functional partners for circuit-level, system-level simulations to understand risk areas and root cause issues.

Assess and debug multi-radio coexistence issues across Apple platforms by performing hands-on hardware experiments, failure analysis, and root-cause investigations at the RF/wireless system level.
Review and sign off on hardware designs, including PCB layouts, flex layouts, system grounding, and shielding, ensuring multi-radio coexistence standards are met before release.
Define and execute validation and characterization test plans, track results, and communicate data-driven insights to cross-functional partners and leadership.
Provide system-level coexistence requirements to chipset teams, validate early EVBs, fine-tune chipset blocking performance and optimize coexistence system mitigation technique.
Collaborate with RF Test Engineers and cross-functional teams to bring up devices under test and develop test procedures, mock-ups, and experimental setups for coexistence validation.
Evaluate system hardware change requests and update characterization plans accordingly, proactively identifying and escalating any coexistence risks or trade-offs.
