About the role

Senior software engineer focused on networking and systems software for SONiC Network Operating System within Apple's IS&T Infrastructure Services. Role spans design, development, debugging, and collaboration across software and hardware stacks to build reliable networking platforms at large scale.

Responsibilities

  • Design, develop, and maintain networking software and features for SONiC-based network platforms.
  • Develop and enhance SONiC components, services, platform interfaces, and networking applications.
  • Debug complex networking problems across the full software and hardware stack: Application/Protocol → SONiC → SAI → ASIC SDK → Network ASIC → Packet Forwarding.
  • Analyze packet-forwarding behavior to determine whether issues originate in the control plane, SONiC infrastructure, SAI, ASIC programming, hardware, or network configuration.
  • Work closely with network ASIC vendors to understand SDK/SAI interactions when investigating forwarding or hardware-programming issues.
  • Develop software that programs and manages switching hardware through SAI.
  • Troubleshoot complex Layer 2 and Layer 3 networking issues, protocols, and technologies.
  • Build tools and automation that improve debugging, observability, testing, and operational reliability of the network platform.
  • Participate in design reviews, code reviews, testing, qualification, and production troubleshooting.
  • Collaborate with network architects, hardware engineers, ASIC vendors, validation teams, and operations teams to deliver highly reliable networking platforms.

Qualifications

  • Strong software development experience in C/C++, Python, Go, or similar systems programming languages.
  • Strong understanding of computer networking fundamentals.
  • Experience developing or working with network operating systems, switching software, routing platforms, or network infrastructure software.
  • Working knowledge of SONiC architecture and its major components.
  • Working knowledge of SAI and how SONiC uses it to program switching ASICs.
  • Working knowledge of network switching ASIC architecture.
  • Strong Linux systems knowledge, including Linux networking.
  • Excellent debugging and troubleshooting skills, with the ability to systematically isolate problems across multiple software and hardware layers.
  • Ability to analyze logs, packet captures, database state, protocol state, and ASIC programming state to identify root causes of complex networking issues.
  • Strong software engineering fundamentals, including data structures, concurrency, APIs, testing, source control, and software design.
