I have worked at Walmartlabs for last couple of years. My experience is mixed as i have changed multiple teams over time. There are some really awesome high visibility teams whereas some are really bad. I would be able to help you more if you know the team. Compensation is pretty much inline with other competitors in bay area. I can give more details if I know the level.
what is walmart ecommerce? are they going to compete Amazon?
Walmart has a big e-commerce team in their Sunnyvale and San Bruno offices that do the development work for all of Walmart and Sam's club websites and smartphone apps. I believe they are collectively called Walmart Labs. p.s. Anyone here use Walmart's new iOS app? It's actually quite good and we'll done.
