Job description

More than 3 billion people in over 180 countries use WhatsApp to stay in touch with friends and family, anytime and anywhere. In India, it is also where a great deal of everyday life gets done — people message businesses, coordinate their families, and increasingly send money as easily as they send a message. 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 Android engineer at WhatsApp you will use your start-up mindset 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 direction for a team's technical area, lead major initiatives end to end, and be one of the people the pillar relies on to make the right engineering trade-offs under real ambiguity.
