Senior Software Engineer, Frontend

Airbnb

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. The interfaces we build are how thousands of Airbnb engineers experience that work - turning a powerful agentic testing platform into something intuitive, fast, and a pleasure to use. You will join a high-impact group of engineers who care about craft and user experience in equal measure. THE DIFFERENCE YOU WILL MAKE As a Senior Frontend Engineer, you will build and maintain the frontend for our Quality Platform and tools - the paved path that gives Airbnb engineers streamlined access to our agentic testing platform. Your primary objective will be to make complex testing and automation workflows simple to understand and effortless to act on, so engineers can validate and ship high-quality software with confidence. In this role, you will: * Own the Quality Platform frontend: Design, build, and maintain the web surfaces that expose our agentic testing capabilities to engineers across Airbnb. * Make the agentic platform accessible: Translate sophisticated, AI-driven testing workflows into clean, intuitive interfaces that reduce friction and accelerate feedback loops. * Improve developer and QE productivity: Identify UX bottlenecks in how engineers discover, run, and interpret tests, and solve them with thoughtful, well-built frontends. * Partner across the stack: Work closely with backend, infrastructure, and applied-AI engineers to surface platform capabilities in the product in a coherent, scalable way. A TYPICAL DAY * Collaborate with the Quality Platform, Mobile Infrastructure, Product Engineering, and Quality Engineering teams to design and develop high-quality UX. * Build and maintain web UI surfaces that give engineers streamlined access to the agentic testing platform - from running and orchestrating tests to exploring results, coverage, and insights. * Be an active contributor by creating high-quality, tested pull requests and reviewing others' designs and code. * Build appropriate tests to ensure the reliability and performance of the software you create. * Create and present your own design, product, and architecture documents, and provide feedback on others'. * Visualize large amounts of data - test suites, test cases, test runs, test results, coverage, run history - in a clean, concise, and actionable fashion. * Stay up-to-date with the latest trends and best practices in web development and performance engineering, and partner with applied-AI work where the UI exposes agentic capabilities. * Do all this in an opinionated fashion, with humility and curiosity, as we are our own product managers. YOUR EXPERTISE * 5+ years of industry engineering experience. * Fluency in HTML, CSS, TypeScript, React, and related web technologies. * Experience with modern JavaScript libraries and tooling (e.g. React, npm, webpack). * Experience building internal tooling or developer-facing UX, ideally for platforms, infrastructure, or developer/quality tooling. * Expertise in visualizing large amounts of data in a clean, concise fashion. * Context around Quality Engineering, testing, or automation tooling is helpful but not strictly necessary - curiosity and willingness to learn the domain matter more. * Interest in or hands-on exposure to Applied AI / LLM-based systems is a plus, as you'll be building the surfaces for an agentic platform. * Solid engineering and coding skills, with demonstrated knowledge of practical data structures and asynchronous programming. * Strong collaboration with colleagues across multiple timezones. * Strong communication and organizational skills. * Ability to work in areas outside of your usual comfort zone and show motivation for personal growth without a dedicated product manager. 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.

ABOUT THE ROLE We're looking for a Senior Software Engineer (Backend/Infrastructure) for the VTEX Network team ,the core connective tissue of our cloud platform: CDN, Cloud Connectivity, Ingress, DNS, and Service Mesh. You'll take on one of our hardest engineering challenges: evolving our Service Mesh. Today VTEX runs a custom, highly performant router (built in .NET) that acts as our service mesh, processing millions of requests per second as the backbone for every VTEX application. Your mission is to help evolve this mission-critical infrastructure toward a market-standard stack (like Istio) with zero downtime and the reliability thousands of stores depend on. This sits at the deep intersection of software engineering and scalable infrastructure, and it rewards real care for performance, resilience, and system architecture. ABOUT THE TEAM The Cloud Network team ensures the reliability, scalability, and performance of the platform that powers thousands of stores worldwide. As part of a recent transformation, we're building a new generation of infrastructure systems: Service Mesh, networking, and compute layers. Our goal is a platform where infrastructure complexity is abstracted away, so engineers move faster without trading off reliability or performance. WHAT YOU WILL DO * Drive the architectural evolution from our custom routing layer to a modern, market-standard Service Mesh (e.g., Istio); * Design, build, and maintain network components that sustain millions of requests per second at very low latency; * Keep VTEX's core network services (Ingress, DNS, Service Mesh, CDN) continuously available and resilient for thousands of stores globally; * Apply deep service-design principles to build scalable, robust, maintainable backend services and infrastructure tooling; * Use AI as a daily multiplier (for development, refactoring legacy internals, testing, and documentation) while exercising judgment about where it does and doesn't belong in critical infrastructure; * Raise the team's bar: mentor other engineers, document for both technical and non-technical audiences, and take an active part in hiring. WHO YOU ARE * A strong backend/platform engineer with deep, hands-on experience operating and evolving Kubernetes infrastructure; * You've designed and run systems for mission-critical, high-throughput environments (millions of requests per second), and you're at home troubleshooting them under pressure; * You know service design and distributed systems well, including networking fundamentals (TCP/IP, HTTP, DNS, proxies) and microservices communication; * You're comfortable working inside complex legacy systems while building their replacement. Experience with .NET is a real plus for understanding and refactoring our current router; familiarity with Service Mesh (Istio, Envoy) is highly desired; * You treat ambiguous, high-stakes problems as yours to make precise, and you weigh decisions by their effect on the whole system, not just your component; * You use AI fluently in your own work and have a clear point of view on when it helps and when it doesn't; * You communicate and negotiate technical trade-offs clearly across teams, and with non-technical partners; * Advanced English for our global, remote-first environment. HOW WE HIRE Our process is built for how engineers actually work in 2026: a take-home you complete with the AI tools you'd really use, followed by a live session where we dig into your decisions and solve a problem together. We're far more interested in how you think than in whether you memorized an algorithm. #LI-Remote  ---------------------------------------------------------------------------------------------------------------------------------- ABOUT VTEX VTEX (NYSE: VTEX) is the composable and complete commerce platform that delivers more efficiency and less maintenance to organizations seeking to make smarter IT investments and modernize their tech stack.
