Our API is designed from the ground up to power Retrieval-Augmented Generation (RAG) and real-time reasoning in AI systems. By connecting LLMs to high-quality, trustworthy web content, we help developers build agents that are not only intelligent - but also informed. \nWe work with some of the most innovative teams in AI - from small startups shaping the ecosystem to the largest enterprises deploying AI at scale. Whether it's powering sales assistants, research copilots, or internal knowledge tools, we're the missing link between LLMs and the real world. \nThe Role\nWe are looking for a Senior Software Engineer to build the rendering infrastructure behind a novel search engine designed for agentic AI. In this role, you will design systems that transform modern web applications into high quality structured content for search and AI. You will work on browser rendering, JavaScript execution, and large-scale rendering infrastructure capable of processing billions of pages efficiently. Modern websites increasingly rely on client-side rendering, dynamic data loading, and complex application frameworks. Your work will ensure we can reliably render, understand, and extract valuable information while minimising cost and latency. \nIn this position, your responsibility will be to:\nDesign and build large-scale rendering systems for modern web applications\nDevelop browser-based rendering infrastructure capable of executing complex JavaScript applications reliably\nResearch how modern frontend frameworks render and deliver content\nImprove rendering quality, completeness, and performance across diverse websites\nOptimise rendering cost, latency, resource utilisation, and throughput at internet scale\nTranslate rendering research into reliable production systems\nYou may be a good fit if you:\nHave 5+ years of experience as a software engineer working on production backend or infrastructure systems and are an expert in several of the following areas:\nBrowser Rendering\nChromium rendering pipeline - DOM, Layout, Paint, and Compositing\nJavaScript execution inside browsers and rendering lifecycle and page readiness\nHeadless browser execution and browser instrumentation\nChrome DevTools Protocol (CDP)\nPlaywright, Puppeteer, Selenium, or similar frameworks Modern Web Applications\nReact, Vue, Angular, Svelte, and modern frontend architectures\nServer-side rendering (SSR), client-side rendering (CSR), and streaming rendering\nSingle-page applications (SPA) and Progressive Web Apps (PWA)\nResource loading, lazy loading, and modern JavaScript bundles\nStrong candidates may also have experience with:\nBuilding and operating high-throughput content processing pipelines at internet scale\nDistributed systems design and performance optimisation\nOpen-source contributions or active involvement in the engineering community\nConference talks or technical publications\nWe conduct coding interviews as part of the process.\n\nWhy Tavily? \nFull ownership - small team, you own the entire infrastructure, not a slice of it \nReal scaling challenges - bursty scraping workloads, cache invalidation, multi-region, millions of daily requests \n AI-native company - your infra directly powers AI agents used by leading companies in the space.","description_format":"text","description_chars":3324,"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":"Germany","iso":"DE","kind":"region"},{"name":"France","iso":"FR","kind":"region"},{"name":"United Kingdom","iso":"GB","kind":"country"},{"name":"Austria","iso":"AT","kind":"region"},{"name":"Belgium","iso":"BE","kind":"region"},{"name":"Bulgaria","iso":"BG","kind":"region"},{"name":"Croatia","iso":"HR","kind":"region"},{"name":"Czech Republic","iso":"CZ","kind":"region"},{"name":"Denmark","iso":"DK","kind":"region"},{"name":"Finland","iso":"FI","kind":"region"},{"name":"Hungary","iso":"HU","kind":"region"},{"name":"Ireland","iso":"IE","kind":"region"},{"name":"Israel","iso":"IL","kind":"country"},{"name":"Italy","iso":"IT","kind":"region"},{"name":"Netherlands","iso":"NL","kind":"country"},{"name":"Norway","iso":"NO","kind":"region"},{"name":"Poland","iso":"PL","kind":"region"},{"name":"Romania","iso":"RO","kind":"region"},{"name":"Spain","iso":"ES","kind":"region"},{"name":"Sweden","iso":"SE","kind":"region"},{"name":"Switzerland","iso":"CH","kind":"region"},{"name":"Estonia","iso":"EE","kind":"region"},{"name":"Greece","iso":"GR","kind":"region"},{"name":"Iceland","iso":"IS","kind":"region"},{"name":"Latvia","iso":"LV","kind":"region"},{"name":"Liechtenstein","iso":"LI","kind":"region"},{"name":"Lithuania","iso":"LT","kind":"region"},{"name":"Luxembourg","iso":"LU","kind":"region"},{"name":"Malta","iso":"MT","kind":"region"},{"name":"Portugal","iso":"PT","kind":"region"},{"name":"Slovakia","iso":"SK","kind":"region"},{"name":"Slovenia","iso":"SI","kind":"region"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","AI Development Tools","AI Search"],"lifecycle":[{"event":"open","at":"2026-08-13T11:09:22Z"},{"event":"close","at":"2026-09-23T16:28:25Z"},{"event":"reopen","at":"2026-10-12T08:48:07Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":1,"p_active":0.348,"p_room":0.44,"age_days":66,"expected_fill_days":62,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/tavily-senior-software-engineer-agentic-search-web-rendering-engineer","json_url":"https://alion.io/job/tavily-senior-software-engineer-agentic-search-web-rendering-engineer.json","meta":{"generated_at":"2026-10-19T10:36:53Z","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":7401,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":6397},"rest":"https://alion.io/mcp/rest/get_company?id=6397"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftavily-senior-software-engineer-agentic-search-web-rendering-engineer"},{"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%2Ftavily-senior-software-engineer-agentic-search-web-rendering-engineer"},{"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%2Ftavily-senior-software-engineer-agentic-search-web-rendering-engineer"},{"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/tavily-senior-software-engineer-agentic-search-web-rendering-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftavily-senior-software-engineer-agentic-search-web-rendering-engineer"}]}
