Airbnb was born in 2007 when two Hosts welcomed three guests to their San Francisco home, and has since grown to over 4 million Hosts who have welcomed more than 1 billion guest arrivals in almost every country across the globe. Every day, Hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way.

Airbnb is a mission-driven company dedicated to helping create a world where anyone can belong anywhere. It takes a unified team committed to our core values to achieve this goal. Airbnb's various functions embody the company's innovative spirit and our fast-moving team is committed to leading as a 21st century company.

The Community You Will Join

Trust Platform Engineering

Everyone at Airbnb thinks about trust, but our team obsesses over it daily. The Trust team is responsible for protecting our community and platform from fraud while also ensuring our hosts, guests, homes, and experiences meet our high standards. Trust Platform is responsible for foundational systems that power the detection and mitigation of fraud at scale across Airbnb, such as the rules engine, friction framework, and vendor API gateway, and supports one of the highest throughput systems across the company. The team works closely with the Trust defense teams to tackle the changing landscape of fraud attacks, and build platform features to enable Trust product teams to quickly build frictions, rules, and enforcement tools for agents.

The Difference You Will Make

As a Senior iOS Software Engineer on the Trust Platform team, your expertise will be pivotal in developing and evolving the friction framework used for mitigating fraud across the Airbnb iOS application. You will work closely with a team of cross-platform engineers with collective expertise in web, native, and backend development to define and shape the future of the friction framework with initiatives such as Airlock SDUI. The friction framework is used by Airbnb engineering teams to build frictions, and is pivotal in protecting our community and platform from fraud while also ensuring our millions of hosts, guests, homes, and experiences meet our high standards.

  • Partner with Airbnb product teams to understand their pain points, pilot proposed solutions, and drive adoption of paved path tooling and frameworks.
  • Participate in all phases of software development including architecture/design, implementation and testing.
  • Support teammates in enabling code quality, operational excellence, and shared learning.

Your Expertise

  • 5+ years industry experience in native iOS development, with a focus on creating and maintaining iOS libraries and SDKs for consumption by other iOS engineers.
  • Experience in the Trust/Fraud domain is a strong plus.
  • Bachelor’s and/or Master’s degree, preferably in CS, or equivalent experience.
  • Extensive experience working with Swift, iOS Applications, GraphQL and REST APIs.
  • Excellent engineering and coding skills. Solid understanding of client networking, performance, caching, client storage solutions, accessibility, and asynchronous programming.
