Pros
SpareFoot is a terrible place to work and nobody in their right mind should ever consider working there. Well this is what I got reading the last negative review from a "former employee" of SpareFoot. I think this is all BS and from a frustrated employee. I was at SpareFoot as the company went from 6 developers to 35 so I have seen lots of changes over the years. Like any other startup in early stage SpareFoot acquired a fair amount of technology debt and have been paying off a very big chuck of it over the last year or so. SpareFoot took the right approach of migrating from a monolithic app to a micro-service infrastructure. That involved a fair amount of changes and it was a very stable environment but the changes were communicated regularly and the website never went down for more that 15 minutes, that's not what I call chaos. SpareFoot will treat its developers like adults, so they will trust that you will do whatever you are required to be successful. They will expect you to have an undestranding of the overall architecture superior to what you would be required as most other software shops in town. As a developer this gives you more tools to grow in your career and realistically, SpareFoot is just ahead of the curve and most web business will be following many of the same practices over the next years. You just have to go to technical conferences (that SpareFoot will pay for) to see that. Nothing is perfect but you will find that the developers, for the most part, are genuinely nice people and that they will help you beyond the scope of their own work. If you have an opinion you will get management actually listen to you. SpareFoot truly lives by its core values and I am pretty impressed how they managed to onboard so many people without losing too much of it.Nobody is required to work weekends and you can have a real work-life balance.
Cons
Some of the developers are not carrying their own weight. The desks are really small and expect close proximity with your peers, it may prevent some people to perform well. Sometimes I wished we would have been more mature, like at the Startup games.
