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.</p> <p>Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.</p> <p>Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&amp;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&amp;D.</p></div><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>The Product</strong></p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">In 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.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">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.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>The Role</strong></p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">We are looking for a Senior Software Engineer to work on the runtime systems of a novel search engine tailored for agentic AI consumption.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">In this role, you will focus on building low-latency, high-throughput systems that serve search queries in real time. You will work on the critical path of user-facing requests, where performance, predictability, and efficiency directly impact product quality. You will design and operate systems that handle thousands of requests per second under strict latency budgets, optimising every layer from request handling to data access and response assembly.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>In this position, your responsibility will be to</strong></p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:l
