Senior Software Engineer, Frontend

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 Platform team is at the heart of Airbnb’s mission to deliver a seamless, high-quality experience for millions of hosts and guests. We don’t just find bugs — we build the systems that prevent them. Our team sits at the intersection of Quality Engineering, Infrastructure, and Applied AI. We are evolving how software quality is built by integrating LLMs, intelligent automation, and data-driven systems into the testing lifecycle. You will join a high-impact group of engineers focused on building AI-powered quality systems that scale across one of the world’s most complex codebases. The Difference You Will Make: As a Senior Software Engineer, you will play a key role in building and evolving AI-native quality workflows across Airbnb. You will design systems that apply AI directly to the testing lifecycle, helping developers and quality engineers build, validate, and ship high-quality software at scale. In this role, you will: * Build AI Agents for the Testing Lifecycle: Design and implement AI agents that support developers and quality engineers across the testing lifecycle — from test case generation and evolution to automation and maintaining test coverage as the codebase changes. * Advance AI-Native Quality: Move beyond traditional automation by building systems that continuously adapt test coverage based on code changes and system behavior. * Improve Developer and QE Productivity: Identify bottlenecks in testing and CI/CD workflows, and solve them through intelligent automation that reduces manual effort and accelerates feedback loops. * Integrate AI into Engineering Workflows: Embed AI capabilities into real development environments, enabling both developers and quality engineers to receive contextual, actionable insights during development and testing. A Typical Day: * Hands-on Development: Build end-to-end systems and tools (TypeScript, Swift, Kotlin, Java, Python) that will power Airbnb’s AI quality platform. This includes services, developer tooling, and UI surfaces that integrate AI into testing frameworks/infrastructure, CI/CD pipelines, and everyday developer workflows. * Applied AI: Develop AI-assisted capabilities such as context-aware agentic E2E validation on pull requests, agentic execution of business-critical flows as quality gates, agentic surface discovery and exploratory testing, and systems for test case generation, and coverage maintenance. * System Design: Participate in the design of scalable AI-driven systems operating within large-scale engineering environments. * Cross-Functional Collaboration: Work closely with Mobile, Infrastructure, Product Engineering, and Quality Engineering teams to integrate AI into real-world development workflows. * Experimentation & Iteration: Explore approaches such as prompt engineering and RAG (Retrieval-Augmented Generation) to improve system effectiveness and adaptability. * Mentorship: Provide technical guidance and help raise the bar for applying AI in engineering systems across the team. Your Expertise: * Experience: 5+ years of software engineering experience in high-scale environments, ideally building platforms, infra, or developer/quality tooling, with exposure to or strong interest in AI/ML or LLM-based systems. * Quality / DexEx/ Tooling Systems : Experience with testing frameworks, CI/CD pipelines, developer experience tooling, or quality engineering platforms. * Applied AI / LLMs: Hands-on experience building applications using LLMs (prompting, APIs, RAG, evaluation, or similar) is a strong plus. * Fullstack & Platform Engineering: Experience building both client and server-side systems. You can work on modern web/mobile stacks(Swift, Kotlin) and tooling, as well as the supporting backend services (Java, Python). * Systems Thinking: Understanding of distributed systems, CI/CD workflows, and large-scale software architectures. * Problem Solving: Ability to navigate ambiguity and design practical, scalable solutions. * Communication: Strong ability to collaborate across teams and explain complex concepts clearly. Our Commitment To Inclusion & Belonging: Airbnb is committed to working with the broadest talent pool possible.

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 Difference You Will Make: The Service Tools team’s mission is to enable Airbnb backend developers to develop, test, and maintain their code quickly and reliably. This team is responsible for the standard development lifecycle for service owners—everything from AI Integration for service development, to how integration tests work, to building services for deployment. This represents Airbnb’s largest cohort of developers, you will ultimately be responsible for their productivity. A Typical Day:  As an engineer on Service Tools, you will work on technologies that help shape an industry-leading end to end developer experience for backend developers. In this role you will be: * Building our next-gen build system using the latest technologies (e.g., Bazel). * Working on integrations between the build system and CI/CD tooling (e.g., merge queues, code coverage, integration testing). * Improving the editor (e.g., IntelliJ) experience for all backend developers. * Helping to shape the technical strategy that directly moves our core metrics (Developer Experience, Developer Velocity, Debuggability, Resilience and Reliability) while reducing cost. * Partnering with engineering leaders across all Airbnb teams for adoption of the new capabilities. Your customers will be all engineers at Airbnb. * A player/coach of our high-performance team to ensure code quality, commitment to craft and operational excellence. Your Expertise: * FLUENT IN ENGLISH (PROFESSIONAL LEVEL) * 6+ years industry experience. * Bachelor’s and/or Master’s degree, preferably in CS, or equivalent experience. * Proficiency in one or more back-end server languages (Java/Ruby/Go/C++/etc.). * Experienced in architectural patterns of a high-scale distributed products/services, such as well-designed APIs, data pipelines and efficient algorithms. * Experience or desire to work collaboratively in cross-functional teams with design, product and data science partners. * Experience working directly on build systems, and even better if you have hands-on experience with Bazel. * Experience working with large monorepos. * Extensive JVM experience. * Want to tackle projects with large open-ended scope and drive significant business impact. * Love collaborating via product reviews, code reviews and architecture discussions. * Are motivated to improve their teammates’ productivity. * Are excited to join an impactful infrastructure team.
