prowess. We hire the best engineers and give them the most complex infrastructure problems to solve. We
push for quality and not quantity. As our CTO/EVP(Engineering) Ken Duda puts it "It’s in our culture, quality is

products in the offering, we are planning to strengthen the India team. If you are looking for an authentic
software engineering job where you can make a fundamental impact at the core infrastructure level, you

networking domains to work at Arista.
What will you get to do as a Software Engineer at Arista?
At Arista software engineers are the real deal - they do a lot more than simply writing code. You will work on
the whole development process, including:
• Suggesting and deciding what features to build

when you work with peers who are equally good or better.
• Flexibility - Our engineers enjoy the utmost flexibility as we believe in judging by the output and not
by the hours worked. Our performance review process is designed to reflect this - we believe that
our best engineers know how to work and do not need to be told what to do.
• Truly global work - What we do in India is exactly the same as what we do in San Jose, Nashua,
Vancouver, Dublin, and other worldwide locations. You don’t have to move out of India to do
cutting edge software - at Arista you can do it right here.

conscious, innovating and disrupting our own products and we can go on. A mind-set that is hard to
get in $15b+ market cap public company.
