Senior Software Engineer (Agentic Search) – Web Rendering Engineer

Accountabilities:

• Design and build large-scale rendering systems capable of processing modern web applications at internet scale.


• Develop reliable browser-based infrastructure capable of executing complex JavaScript applications and accurately capturing rendered content.


• Research how modern frontend frameworks render and deliver content across different architectures and execution environments.


• Improve rendering quality, completeness, reliability, and performance across a wide range of websites.


• Optimize rendering infrastructure for cost, latency, resource utilization, throughput, and scalability.


• Investigate browser rendering behavior, page readiness, resource loading, and dynamic content execution.


• Translate research and experimentation into reliable, maintainable production systems.


• Help address large-scale infrastructure challenges including bursty workloads, caching, multi-region systems, and millions of daily requests.


• Take end-to-end ownership of rendering infrastructure and contribute to technical decisions across the system.


• Collaborate with engineering teams to ensure rendering capabilities reliably support agentic search and AI workloads.

Requirements

• 5+ years of professional software engineering experience working on production backend, infrastructure, or distributed systems.


• Deep expertise in several areas of browser rendering and modern web infrastructure.


• Strong understanding of the Chromium rendering pipeline, including DOM, Layout, Paint, and Compositing.


• Strong knowledge of JavaScript execution within browsers, rendering lifecycles, and page readiness mechanisms.


• Experience with headless browser execution, browser instrumentation, and Chrome DevTools Protocol (CDP).


• Hands-on experience with Playwright, Puppeteer, Selenium, or comparable browser automation frameworks.


• Strong understanding of modern frontend architectures and frameworks such as React, Vue, Angular, or Svelte.


• Experience with server-side rendering, client-side rendering, streaming rendering, single-page applications, or progressive web applications.


• Understanding of resource loading, lazy loading, modern JavaScript bundles, and dynamic data delivery.


• Experience designing and operating high-throughput content processing pipelines at internet scale is highly valuable.


• Strong knowledge of distributed systems design and performance optimization.


• Open-source contributions, engineering community involvement, conference presentations, or technical publications are a plus.


• Strong problem-solving skills and the ability to work independently on complex infrastructure challenges.


• Willingness to participate in coding interviews as part of the hiring process.

• Remote opportunity for candidates based in the United Kingdom.


• High degree of ownership over critical rendering infrastructure.


• Opportunity to work on real-world internet-scale challenges involving millions of daily requests and bursty workloads.


• Exposure to multi-region infrastructure, caching, performance optimization, and large-scale content processing.


• Opportunity to build infrastructure directly powering AI agents and agentic search applications.


• Small, highly technical engineering environment with broad responsibility and impact.


• Opportunity to work at the intersection of AI, browser technology, distributed systems, and modern web infrastructure.
