Networking Transport and Protocols Engineer

Networking Transport and Protocols Engineer

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 a wide array of Apple consumer devices as well as for Apple silicon servers running in Apple Data Centers. This provides a unique opportunity to build 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 compromises between several competing factors such as performance (throughput and latency), energy efficiency, ease of use, and security. The focused space spans areas related to data path features and optimizations for improved throughput & latency, user mobility, 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.

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, the 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.

Minimum Qualifications

• BS or higher education in Computer Science or equivalent networking software development experience.
• Strong software design and development skills including C/C++/Swift programming language experience.

Preferred Qualifications

• Knowledge of the TCP/IP suite of protocols (including IPv6) and APIs.
• Experience with transport protocols performance analysis.
• Familiarity with congestion control, flow control, and loss recovery aspects of transport protocols.
• Familiarity with security protocols (like IPSec, TLS) and understanding of threat models.
• Knowledge of BSD/Linux Kernel networking stack design and architecture.
• Experience with Unix networking, including sockets API.
• Experience debugging networking issues using diagnostic tools like Wireshark and tcptrace.
• Experience with software debugging tools like gdb/lldb and dtrace.
• Experience with software performance profiling.
• Enthusiasm and interest in keeping up with trends/research in networking transports/protocols such as HTTP/3, QUIC, and L4S.
