WhatsApp - Software Engineer (Technical Leadership) - iOS

We are building a new team to take WhatsApp further in that direction. The newly established WhatsApp Services team is focused on making WhatsApp more useful for more of what people already use it for, and on building what comes next.

The WhatsApp Services team is treated as a zero-to-one effort so we can move fast, take risks and build as we go - staffed and prioritized, like every other WhatsApp team, from day one. Payments on WhatsApp aren't a bet on paper: live and growing in India, with the existing WhatsApp payments engineering team moving across as the foundation.

As an iOS engineer at WhatsApp you will use your ability to operate with autonomy in ambiguous, fast-moving environments and your full range of engineering skills to produce elegantly simple products. You'll be expected to push the boundaries of what's possible in a mobile app, while sharing our commitment to quality and attention to detail. You will set technical direction across multiple teams, own the architecture for a major area of the product, and shape what WhatsApp Services becomes in India.
