Job Description
Who You’ll Work With
Arista Networks is looking for world-class Software Test Engineers (aka System Test engineers) to help us in building the highest quality networking products for the AGNI team. 
Arista Guardian for Network Identity (AGNI) is Arista’s network identity and access management solution. It provides secure authentication, authorization, and visibility for users, devices, and applications accessing the network. AGNI uses a cloud-native, microservices-based architecture and leverages ML/AI to simplify operations, support zero-trust security, and scale with modern enterprise networks. It integrates with existing identity sources and network infrastructure and is available as both a SaaS and on-premises solution.
If you love networking, working on complex & scaled out network topologies makes you excited and if you like to challenge yourself to find the hard-to-find bugs and if troubleshooting & debugging network and system problems gives you a thrill, this role is tailor made for you.
At Arista, you’ll bring your intelligence, creativity, and drive every day & work with our products exactly how they are going to be used by our end customers and while doing so, make sure that the products are going to work every time. You will engage with our products as end-users would, ensuring their consistent functionality and reliability. 
Your job is to find the hard bugs, the ones not easily exposed by the developers’ automated unit and product level tests. You will NOT spend your time running manual regressions of mind numbing, 1000 page test plans, because Arista’s developers automate all the basic functional and integration tests. 
Courtesy of our super collaborative work environment, you’ll spend your time embedded deeply with multiple engineering teams, working side by side with the developers, POC engineers, account teams, working together as one team and do all of it to help us to explore, find and fix software problems before they can reach the customers. We take quality seriously and we invite you to be a champion of software quality!!
What You’ll Do
Work with the developers in your team in creating their plans for automated tests to complement the exploratory testing that you perform. 
Participate in functional specification and software design reviews held by your team and provide customer centric input. 
Work in a highly productive environment along with the best of the engineers on the Linux platform that cuts a typical development cycle by order of magnitude with a laser focus towards quality. 
Use every means possible to find the bugs in the software and/or hardware being developed by your team. 
Write test plans to validate Arista features and products. 
Design test network topologies to validate functionality, performance, stability and scalability of features and products. 
Execute test plans to verify all aspects of the product. Identify defects and validate resolution. 
Work as an agile member of a combined development and test team, running in short cycles to develop functional software in quick iterations.
Qualifications
