Network systems software is all about managing hardware components on switches and routers. As a software engineer in the Network Systems group, you will collaborate with hardware engineers to design and build novel features that help Arista hardware run effectively and efficiently. You will write software that controls  everything from temperature sensors, fan controllers, power controllers, storage devices to FPGAs, NICs and PCIE switches. You will design abstractions that allow this software to be easily packaged and integrated into hardware drivers that manage all our hardware. You will also get to work closely with our hardware engineers throughout the lifecycle of our products - ranging from influencing hardware designs for ease of software control, to bringing up brand new hardware and taking it through the development cycle to market.

  • Develop and maintain features using C, C++ and Python, review and contribute to functional and design specifications. Build automated tests and test infrastructure to test the features.
  • Work with hardware and manufacturing teams to bring new hardware to market.
  • Collaborate with hardware engineers to design optimal software control interfaces for managing hardware components.
  • Work with Customer Support Engineers and customers to analyze, mitigate and fix problems in customer networks.
  • Work with the System Test Engineers to analyze problems found in their tests and provide fixes for those problems.
  • Mentor new and junior engineers to bring them up to speed in Arista's software development environment.
Qualifications
  • BS Computer Science/Electrical Engineering/Computer Engineering + 3 years experience, or MS Computer Science/Electrical Engineering/Computer Engineering + 2 year experience, or Ph.D. in Computer Science/Electrical Engineering/Computer Engineering +1 year experience, or equivalent work experience
  • Knowledge of C or C++ and Python.
  • Knowledge of UNIX or Linux
  • Experience working with low level hardware components
  • Understanding of IP networking and/or distributed systems is a plus
  • Applied understanding of software engineering principles
  • Strong problem solving and software troubleshooting skills
  • Ability to design a solution and implement features independently. 
  • Ability to work in small teams.
