" Working with cross-functional partners to assess the multi-radio coexistence performance impact to the end user.
" Working with wireless software partners to design the software mitigation scheme, assess the trade-offs and implementation path.
" Bring-up device-under-test, setups and test procedures for multi-radio coexistence performance studies.
" Analyze wireless logs to understand field usage patterns and incorporate these learnings to perform controlled bench performance studies for multi-radio coexistence.
" Proposing HW/SW design and process changes for multi-radio coexistence issues considering design constraints and align with cross-functional partners on trade-offs and implementation path.
" Execution of validation & characterization test plans to meet multi-radio coexistence performance targets.
" Tracking validation status, analyze results and communicate insight from data.
" Collaborating with cross-functional partners for circuit-level, system-level simulations to understand risk areas and root cause issues.
Responsibilities
" Assess multi-radio coexistence user impact across Apple platforms by conducting performance characterization at the RF/wireless system level.
" Work with cross-functional partners to define product-level coexistence performance specifications and align on use-cases, test methodology & key performance metrics.
" Work with analytics team to gather usage statistics to understand prevalence of coexistence issues in the field.
" Collaborate cross-functionally with field team to design experiments & analyze field logs to demonstrate enduser performance impact.
" Design bench experiments, collect performance data & analyze wireless logs across various RF parameters to derive HW specification for various multi-radio coexistence use-cases.
" Define and execute validation and characterization test plans, track results, and communicate data-driven insights to cross-functional partners and leadership.
" Collaborate with cross-functional teams to bring up devices under test and develop test procedures, mockups, and experimental setups for coexistence validation.
" Monitor HW performance throughout the HW builds and scope software mitigation solutions to remedy multiradio coexistence issues observed in the HW.
" Collaborate with cross-functional software partners to determine appropriate software mitigation policies across various Apple platforms based on HW data collected in factory.
" Lead cross-functional efforts to define software mitigation strategies for future technology platforms.
