Senior Software Engineer (Agentic Search) – Web Rendering Engineer

Team: IT

Location: Germany

Commitment: Full-time

Workplace Type: remote

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.

Benefits:

• 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.
