Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 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. The Community You Will Join: The Quality Engineering team helps Airbnb build high-quality software efficiently. We enable Airbnb engineers to build highly testable systems by building and using tools leveraging AI. We own and continuously improve product test cases, automation coverage, test automation tools, environments, frameworks. We navigate Airbnb's massive codebase identifying weak spots, and help design and implement testable fault-tolerant systems. The Difference You Will Make: * Be a leader in Airbnb, leveraging AI to redefine and accelerate Quality Engineering. * As a Senior Mobile Software Engineer, you will help us meet this challenge by building and evolving comprehensive automation coverage for features and releases across both native mobile stacks. You will work directly with the iOS and Android product engineering teams to develop and maintain our test tools, write and test product code, participate in design reviews to architect testable systems, and guide designs and code to enhance modularity and testability. * You are eager to understand complex systems top to bottom and thrive working across technologies and codebases. In addition, you excel at working through ambiguity, concept validation, and implementing best-in-class solutions. * As a global company, our mission is to develop and maintain the necessary quality engineering processes that scale to meet the needs of both our external customers and internal teams. We strive to ensure that our product and support workflows deliver a seamless experience for guests, Hosts, and support agents. A Typical Day: * Leverage AI and tooling to lead the implementation of a test automation strategy, covering the entire testing pyramid (unit, service, integration, and end-to-end testing) to verify feature functionality for customer use cases on iOS and Android. * Lead building, maintaining, and effective utilization of automated tests in Swift and Kotlin, collaborating closely with the mobile engineering teams to ensure robust test coverage for features and releases, and actively participating in the continuous improvement of testing processes. * Contribute to improving existing automation frameworks to support new functionalities and optimize quality and efficiency across both native codebases. * Collaborate with CI/CD team to integrate automated testing into CI/CD pipelines, ensuring thorough test coverage at every stage of development and reducing build and feedback latency for both platforms. * Own the health and signal quality of the mobile automation suite, reducing flakiness, improving execution time and debuggability, and defining the metrics that show whether quality is improving. * Demonstrate excellent troubleshooting abilities, isolate issues, and verify bug fixes. Debug issues found during testing and after release, including device and emulator specific failures. * Be a player of our high-performance team to ensure code quality, commitment to craft and operational excellence * Work closely with cross-functional teams, including product management, development, and other QE teams, in a fast-paced environment with short release cycles. Your Expertise: * 5+ years of industry experience in software engineering and testing * Strong hands-on experience in one native mobile stack (Kotlin/Android SDK or Swift/iOS SDK) and working knowledge of the other, with experience using modern build tools (Gradle, Xcode) * Strong knowledge of test automation methodologies, tools, and frameworks * Strong hands-on experience with mobile automation frameworks (e.g., Espresso, Compose Test, XCUITest) * Experience integrating automated tests into CI/CD pipelines (e.g., Buildkite, Spinnaker, Jenkins, Fastlane) and version control systems (Git) * Experience using quality signals such as coverage, flaky test rate, suite execution time, and escaped defects to prioritize work and demonstrate impact. * Excellent communication skills towards facilitating interactions with cross-functional teams * Expertise developing solutions to ambiguous problems, and integrations across multiple teams with significant impact * Curiosity about applying AI/LLMs to testing and developer productivity. * Comfortable collaborating in English. * Bachelor's degree in computer science/engineering or equivalent Our Commitment To Inclusion & Belonging: Airbnb is committed to working with the broadest talent pool possible. We believe diverse ideas foster innovation and engagement, and allow us to attract creatively-led people, and to develop the best products, services and solutions. All qualified individuals are encouraged to apply. We strive to also provide a disability inclusive application and interview process. If you are a candidate with a disability and require reasonable accommodation in order to submit an application, please contact us at: [email protected]. Please include your full name, the role you’re applying for and the accommodation necessary to assist you with the recruiting process.  We ask that you only reach out to us if you are a candidate whose disability prevents you from being able to complete our online application.   Reasonable Accommodations: We are committed to providing reasonable accommodations throughout the recruitment process for applicants with disabilities. If you need assistance, or an accommodation, please let your recruiter know once you are contacted about a role. A Note on Recruiting Scams: Scammers sometimes pose as Airbnb recruiters to get money or personal information from candidates. A few things that will always be true for Airbnb’s hiring process: our open roles are posted on Airbnb’s Career’s Page at careers.airbnb.com, and our recruiters correspond only from @airbnb.com or @ext.airbnb.com email addresses. Our recruiters will never ask for your Social Security number, bank account details, passport, or payment app information while you are interviewing.  We’ll also never ask you to pay a fee, send money, deposit or cash a check, or purchase work-related equipment (such as a company laptop) during the interview process. We encourage candidates to remain vigilant of these recruiting scams and not share sensitive information if you do not believe an individual is actually affiliated with Airbnb.
