Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way.\nThe Community You Will Join\nThe Experimentation team's mission is to provide an insightful, reliable and easy to use experimentation platform (A/B testing and feature rollout) for customers across the company. Thousands of experiments run on our platform each year. Our team is multidisciplinary, owning UIs for setting up and analyzing experiments, data pipelines and libraries for calculating results, and clients for assignment and delivery. You will work closely with design and data science partners and with the engineers and analysts across the company who use our tools every day.\nThe Difference You Will Make\nYou will co-own the web application where teams set up, manage and analyze experiments and feature configuration, and the AI-assisted workflows that are becoming part of how experiments are designed, validated and read out. You will build features end to end, from the React/TypeScript interface through Python APIs to the data layer, and make our tools intuitive and trustworthy for users with a wide range of statistical backgrounds. Success looks like features that measurably speed up experiment setup and readout, and AI-enabled tools that people adopt because they are reliable.\nA Typical Day\nDevelop new features across the client (React/TypeScript), APIs (Python/GraphQL) and database, and own them from design through on-call.\nWork with design and key customers to shape intuitive experiences, including how to visualize experiment results so users with minimal statistical training draw good conclusions.\nBuild AI-enabled workflows for our users, such as agent tools and skills that help create, validate and analyze experiments, and the interface around them, with evaluations that keep quality high.\nUse AI-assisted development to move faster, and help the team set good practice for it.\nWork with data science partners to bring new methodology into the product.\nParticipate in experiment reviews to understand how customers use the platform and where it falls short.\nYour Expertise\n5+ years in a hands-on software engineering role, shipping high-quality code to production, including full-stack web applications on a modern stack.\nStrong front-end skills: React and TypeScript fundamentals, state and data fetching, performance and testing, and a good eye for intuitive interfaces in data-rich or enterprise tools.\nExperience across the stack: backend APIs in Python or a similar language, GraphQL or comparable API design, and relational database storage.\nHands-on experience with AI: you build with LLMs or agent tooling (tools, skills, evaluations), or you are fluent with AI-assisted development and know how to verify what it produces.\nExperience working directly with customers and design to turn ambiguous needs into shipped, well-designed features, with clear communication.\n[Bonus] Experience with data visualization or data-intensive applications.\n[Bonus] Experience with experimentation platforms.\nOur Commitment To Inclusion & Belonging:\nAirbnb 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.\nWe 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: . Please include your full name, the role you’re applying for and the accommodation necessary to assist you with the recruiting process. \nWe 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.\nReasonable 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.\nA 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.","description_format":"text","description_chars":5280,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Brazil","iso":"BR","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Vacation Rentals","Online Rental Platforms","Travel Technology"],"lifecycle":[{"event":"open","at":"2026-10-27T00:08:42Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":4,"expected_fill_days":44,"reasons":["conf:3","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/airbnb-senior-software-engineer-experimentation-interfaces","json_url":"https://alion.io/job/airbnb-senior-software-engineer-experimentation-interfaces.json","meta":{"generated_at":"2026-10-31T21:42:32Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":33978,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":77},"rest":"https://alion.io/mcp/rest/get_company?id=77"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fairbnb-senior-software-engineer-experimentation-interfaces"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fairbnb-senior-software-engineer-experimentation-interfaces"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fairbnb-senior-software-engineer-experimentation-interfaces"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/airbnb-senior-software-engineer-experimentation-interfaces\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fairbnb-senior-software-engineer-experimentation-interfaces"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3302495}},{"tool":"search_jobs","arguments":{"company":"airbnb.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3302495},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
