- 5.0Working in a fast-growing company with great software infrastructure and great engineersSoftware Engineer • Current EmployeeSanta Clara, California, United StatesFebruary 23, 2012Pros: Arista is growing really quickly, which means there are always new and interesting problems to solve. The engineering team is very good, and management is committed to solving problems the right way (no quick hacks to get a feature out, use automation for building and testing). There is very minimal management, and engineers are encouraged to lead and complete their own projects.Cons: Quick growth means Arista has lost most of its start-up feel, as much as management is fighting that. There is some tendency to see engineering as a sunk cost, and everything else as expensive.
