We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.\nBuilt by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.\nListed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.\nThe Product\nIn a rapidly evolving world, trust in AI depends on AI agents being grounded in fresh, verified real-world data. Search is the foundation that makes this possible. We are building an agent-native search platform designed specifically for AI systems rather than human users. Our product provides programmatic, low-latency, and observable search APIs that AI agents use to retrieve, filter, and reason over real-world information at scale.\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.\nBenefits & Perks:\nCompetitive compensation\nCareer growth and learning opportunities\nFlexibility and ownership\nCollaborative and innovative culture\nOpportunity to work on impactful AI projects\nInternational environment and talented teams\nWhat's it like to work at Nebius:\nFast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI \nEqual Opportunity Statement:\nNebius is an equal opportunity employer.
