WiFi MAC Systems Engineer
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 Wireless Silicon Design group, you will have the unique & rewarding opportunity to develop upcoming and future generations of products to support emerging applications that will delight and encourage millions of Apple’s customers every single day!
In this technical role, you will be at the center of our silicon design group responsible for the wireless systems design of our innovative wireless SoC products. You will have the chance to create algorithms and architectures of wireless communication systems, as well as collaborate with extraordinary HW, SW designers and architects to implement, verify, validate and bring up SoC products to production quality, providing them to millions of Apple customers!
In this role, core responsibilities include, but are not limited to the following:
• Designing and simulating wireless communication systems for very high data rate applications focusing on MAC layer system design and optimizations.
• Analyzing and improving the efficiency of wireless MAC layer protocols, focusing on throughput, latency and overall network performance.
• Implementing MAC system models and investigating algorithms for performance enhancements, design and validate them to allow performance sign-off and enable system developments. Defining the control procedures of the MAC layer hardware modules to achieve robust and optimal performance throughput and latency.
• Collaborating with PHY system team and cross-functional teams to integrate MAC layer algorithms into system architecture
• Collaborating with firmware designers to realize these methods with high efficiency software implementation and possibly with using hardware acceleration.
• Bringing up, testing, characterizing and optimizing real silicon in the lab.
• Documenting design processes and performance outcomes, providing detailed reports and insights for continuous improvements.
