We 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.
In this position, your responsibility will be to:
Design and build large-scale rendering systems for modern web applications
Develop browser-based rendering infrastructure capable of executing complex JavaScript applications reliably
Research how modern frontend frameworks render and deliver content
Improve rendering quality, completeness, and performance across diverse websites
Optimise rendering cost, latency, resource utilisation, and throughput at internet scale
Translate rendering research into reliable production systems
