  • IP routing protocols, such as RIP, OSPF, BGP, IS-IS, or PIM.
  • Layer 2 features such as 802.1d bridging, the 802.1d Spanning Tree Protocol, the 802.1ax Link Aggregation Control Protocol, the 802.1AB Link Layer Discovery Protocol, or RFC 1812 IP routing.
  • Ability to utilize, test, and debug packet forwarding engine and a hardware component’s vendor-provided software libraries in your solutions.
  • Infrastructure functions related to distributed systems such as messaging, signaling, databases, and command line interface techniques.
  • Hands-on experience in the design and development of ethernet bridging or routing-related software or distributed systems software is desirable.
  • Hands-on experience with enterprise or service provider class Ethernet switch/router system software development, or significant PhD level research in the area of network routing and packet forwarding.
  • Applied understanding of software engineering principles.
  • Strong problem-solving and software troubleshooting skills.
  • Ability to design a solution to a small-sized problem, and implement that solution without outside help. Able to work on a small team solving a medium-sized problem with limited oversight.
