At Wayfair, we know that software engineering is a team sport. Broadly speaking, we organize our engineers into small working teams of anywhere between three to eight people. When you have issues getting application code running on your development machine, or questions about features that your team supports, having that small, tight-knit working group to turn to is invaluable. We also organize these teams of engineers with additional cross-functional members such as product managers, design, QA, and analytics.
