[OpenNash Jobs](https://jobs.opennash.com/) / [Meta Platforms](https://jobs.opennash.com/companies/meta-platforms/) / WhatsApp - Software Engineer - iOS

## 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 Brazil, 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 Brazil, with the existing WhatsApp payments engineering team moving across as the foundation. As an iOS 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.

## Responsibilities

Build and ship client features for WhatsApp on iOS, with a focus on performance, reliability and responsiveness. Own iOS client architecture for services surfaces — payments, commerce and the everyday money-centric flows people already come to WhatsApp for. Work across Swift and Objective-C with the iOS SDK, and partner with server and platform teams on API design. Set direction and goals for a team, lead major initiatives and drive them to completion across functions.

Architect efficient and scalable systems that drive complex applications, and make the engineering trade-offs a 0-to-1 effort demands. Identify and resolve performance and scalability issues, and drive large efforts to reduce technical debt. Establish ownership of significant components, features or systems with expert end-to-end understanding. Provide technical guidance and mentorship to peers, help onboard new team members and raise the engineering bar in the team.

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 Brazil.
