About the role

Protecting every step of the Airbnb user journey—from first sign-up and login, to booking, messaging, managing accounts, and beyond.
Detect, prevent, and respond to fraud and abuse using data-driven heuristics, advanced machine learning, and human operations.
Design and build robust backend systems for detecting, investigating, and responding to suspicious behaviors.
Optimize existing services for scalability and reliability.
Own and deliver projects end-to-end, from architecting backend systems to improving reliability of integrations with trust and safety systems.
Collaborate with product managers, data scientists, engineers, fraud intelligence, and operations teams to design solutions that impact user trust and business success.
Investigate unusual user behaviors or new security threats and develop tools or dashboards for faster fraud detection and response.
Write, review, and ship clean, testable code; participate in meetings, code reviews, and design discussions.
Work on enhancements that make it easier for internal operators to review flagged activities or for users to resolve account issues with low friction.
Learn new technologies and best practices in security and user experience to improve safety and usability of Airbnb.

5-10 years of experience building and maintaining web applications, with a focus on both frontend and backend development.
Proficiency in at least one modern programming language (such as JavaScript/TypeScript, Python, Java, or Ruby) and familiarity with web frameworks (e.g., React, Node.js, Express, Django, or Rails).
Solid understanding of core web technologies: RESTful APIs, databases (SQL or NoSQL), and basic security best practices.
Experience with version control (Git), code reviews, and collaborative software development in a team environment.
Eagerness to learn from others, seek feedback, and grow technical skills, especially in security, fraud detection, or user trust domains.
Strong communication skills and a collaborative mindset, with an interest in working closely with product, design, and operations partners.
Bonus: Exposure to authentication, authorization, or trust & safety systems is a plus, but not required.
