and the entire internet. Our switches and routers are the backbone of large data centers that host Microsoft
Azure, Google Cloud, Facebook etc. High Frequency Traders rely on Arista to provide ultra-low latency network.
In India Arista powers the Flipkart’s Big Billion Day Sale event which has over billion transactions happening in
real time. Besides, we also provide the last mile connectivity for campus wide networking (both wired and
wireless) through our Cognitive Cloud Networking solutions. Arista disrupted the traditional infrastructure
technology by pioneering the move from hardware to Software Defined Networks, Cloud and now to greater
network visibility through telemetry and data analytics solutions. All this is possible because of the strong
product engineering innovation that is the core of Arista’s DNA. At Arista we take pride in our engineering
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
the most important thing. Getting it right is more important than feature velocity, ship dates and new
platforms".
With over 400+ engineers in Bangalore and Pune are a big part of Arista’s technology leadership. With new
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
should be talking to us - we are looking for aptitude and attitude ; you need not have worked in wireless or
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
• Driving the design and architecture
• Pushing, testing, documenting the feature
• Working alongside customers in the field if needed
You will get to work with the best in your field and learn how to write amazingly reliable software - At
Arista everyone is hands-on including our managers, directors, VP’s and of course our CTO!
Are you right for this role?
Do you like coding? Does your adrenaline go up when you have difficult problems to solve? For success at
Arista all you need is:
• Strong engineering and Computer Science fundamentals
• Extensive background in algorithms and strong software architecture skills
• Fluency in one or more of these programming languages: C, C++, Python, Go, Java, JavaScript
• Hands-on experience with design and implementation in a strong product-engineering environment
• Self-driven and self-motivated - At Arista we empower engineers to work on their own with very little
supervision and management.
Why Arista?
As a great software engineer we know that you have multiple options to choose from. So why Arista? It is
because:
• Learning - A hands-on job like Arista’s is the best learning experience you can hope to get especially
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.
• Large company with a start-up mind-set - We work like a start-up - less management, cost
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.
We are looking for Senior Backend Engineers to design and build the systems that power our core business of lending and loan processing. As a Senior Backend Engineer you will be expected to contribute significantly to your team. Your work is consistently of high quality. You solve complex problems, applying appropriate technologies, design patterns, and best practices. Your focus is on a major portion of existing or new team software. You work with your team to design and build software that is secure, correct, observable, and resilient. Your solutions are pragmatic.

- Debug and resolve production issues; take part in blameless postmortems
- Plan and execute smooth migrations to new technology as a way of managing technical debt

- Contribute to the improvement of your team’s code review standards, design discussions, team planning, and AARs.
You may shine in this role if you
- Have a track record of shipping software in a distributed systems environment
