Job Description

Cupertino, California, United States

Software and Services

The Networking team at Apple creates foundational technologies that enable Apple products to communicate reliably, efficiently, securely, and privately with each other and 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 next-generation networking technologies for a wide array of Apple consumer devices and Apple silicon servers running in Apple Data Centers. This provides a unique opportunity to build solutions that work across various platforms with different hardware capabilities.

The solutions need to be designed to work with different underlying link layer technologies (low-rate wireless PAN links, Wi-Fi, Cellular, High Speed Data center networking, etc.) under various network impairments. The position requires resolving appropriate compromises between competing factors such as performance (throughput and latency), energy efficiency, ease of use, and security.

The focused space spans from areas related to data path features and optimizations for improved throughput and 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.

Key Responsibilities

Requirements

  • 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
  • Strong system programming fundamentals
  • Knowledge of the TCP/IP suite of protocols (including IPv6) and APIs
  • Experience with transport protocols perf 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 diagnostics 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

Additional Requirements

  • Pay and Benefits
  • At Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $175,800 and $312,200, and your base pay will depend on your skills, qualifications, experience, and location.
  • Apple employees also have the opportunity to become an Apple shareholder through participation in Apple's discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple's Employee Stock Purchase Plan.
  • You'll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses — including tuition.
