Apply 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? Do you like changing the game? 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.
Apple’s Wireless Systems and Compliance Engineering team is looking for a Wireless RF Hardware Engineer to do system engineering to ensure wireless regulatory compliance for new Apple products with advanced radio technologies.
- Apply wireless system design/characterization knowledge towards addressing emission regulatory requirements in consumer products.
- Translate various emission requirements into system requirements for new chipsets and platforms.
- Perform debugging of marginal/failure tests and will interact with multifunctional teams like RFHW/Antenna/Product Design/EE to drive design changes and address issues.
- Perform HW failure analysis at the RF/wireless system level to identify root-cause of marginal/failing behaviors making use of hands-on experimental modifications to hardware.
- Propose design and process changes for RSE issues considering design constraints and align with cross-functional partners like RFHW/Antenna/Product Design/EE on trade-offs and implementation path.
- Review designs and sign-off on releases of PCB layouts, flex layouts, system level groundings, shielding.
- Collaborate with cross-functional partners for circuit-level, system-level simulations to understand risk areas, root cause issues, and pre-fetch potential emission concerns.
- Architect and coordinate execution of software features, which are necessary for regulatory compliance.
- Pre-fetch potential emission concerns using simulation tools and schematic reviews.
- Collaborate with the engineering teams to define emission test plans for custom features. That would include defining requirements for custom testing solutions and working with test equipment vendors.
- Drive Apple's proprietary Wireless design, verification & adherence to Worldwide Regulatory/Compliance requirements.
- Collaborate with System/EE, PD, HW Design, Chipset team, Antenna, and Product design teams to ensure Apple's upcoming Technology/Product integration are aligning with Compliance requirements.
- Review and sign off on hardware designs, including CB layouts, flex layouts, system grounding, and shielding, ensuring regulatory compliance requirements are met.
- Characterization of Apple wireless products towards compliance of WW requirements.
- Debug/FA Wireless compliance related issues by performing hands-on hardware experiments, failure analysis, and root-cause investigations at the RF/wireless system level. Collaborate with HW Design, FEM Vendors, Chipset vendors, Antenna, and Product design to come up with HW fixes.
- Driving Chipset design requirements based on RF/Regulatory compliance requirements.
- Defining & implementing various SW/FW features including Regulatory Power tables.
- Performing Schematic/layout reviews and HW fixes via mockups.
- Review World-wide Wireless Regulatory/Compliance specs and develop test plans.
- Bachelor's Degree with 10+ years of relevant work experience.
- Industry experience in development/characterization of RF/Antenna system for wireless technologies. Experience on commercializing products for Cellular/ WLAN is required.
- Experience with regulatory/industry conformance specifications for consumer products.
- Experience in RF layout review, radiated sub-system review, and system grounding.
- Experience with one of the tools like MATLAB, HFSS, CST, ADS.
- Master's Degree with 10+ years of relevant work experience preferred.
- Detailed understanding of at least one Wireless technology including 5G FR1, FR2, GSM, UMTS, CDMA, LTE, 802.11a/b/g/n/ac/ax/be, Bluetooth, Thread, UWB, NFC.
- Understanding of regulatory features like DFS, Adaptivity, and Power Table.
- Experience with radiated test methodology, equipment, and 3m Chamber.
