Role Number:200574809
The Networking team creates foundational technologies that enable Apple products to reliably, efficiently, securely, and privately communicate to each other and the rest of the world. The team achieves this through invention and implementation of new technologies, collaboration inside and outside of Apple, and standardization across the industry. You would participate in the architecture and development of the next generation networking technologies for wide array of Apple consumer devices as well as for Apple silicon servers running in Apple Data Centers. This provides unique opportunity of building solutions that work across a variety of platforms with different hardware capabilities. The solutions need to be designed such that they work with different underlying link layer technologies (low-rate wireless PAN links, Wi-Fi, Cellular, High Speed Data center networking etc.) under a variety of network impairments. The position will require the candidate to resolve appropriate compromise between several competing factors such as performance (throughput and latency), energy efficiency, ease of use and security. The focused space spans from areas related data path features and optimizations for improved throughput & latency, user mobility to user privacy and security. The role is extremely cross functional and you will work with App developers, API frameworks teams, server side teams, network device driver teams, privacy and security teams etc.

Description

The ideal candidate will enjoy working in a fast-paced environment, handle multiple assignments in parallel, and be self-driven to be effective in an environment with little overhead. The candidate also needs to show initiative, ability to take ownership of a problem area, and demonstrate an ability to understand the role of the group's technology in the larger context of the product and network environment. The position has cross-functional aspects, and you will need to show excellent interpersonal and communication skills.
