About this role
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 a full-stack product 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 in 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.

Identify and solve the hardest technical problems across the pillar, including finding where new technology can address previously intractable problems.
Set technical direction across multiple teams and own the architecture for a major area of the product.
Lead initiatives of org-wide scope, resolving ambiguity in both product definition and technical approach.
Drive engineering standards, quality and craft across the pillar, and make teams and systems work better to increase their impact.
Mentor senior engineers, influence cross-functional partners in product, design and data science, and act as a credible co-owner of product outcomes.
Collaborate with cross-functional teams in product management, design, data science and operations to build innovative application experiences.
Partner with payments, legal, compliance and local operations partners to ship services that meet the reliability and regulatory bar expected in India.
