Staff / Senior Software Engineer (Agentic Search) - Crawler

ppbAbout Nebius: /b /ppNebius is leading a new era in cloud infrastructure for the global AI economy. 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. /ppBuilt by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI. /ppListed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with RD 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 RD. /ppbThe Product /b /ppIn 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. /ppWe 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. /ph3The Role /h3pWe are looking for a Senior Software Engineer to work on the content acquisition and crawling infrastructure of a novel search engine tailored for agentic AI consumption. /ppIn this role, you will focus on building systems that discover, fetch, and continuously refresh content from the open web and other large-scale data sources. You will design distributed crawling, scheduling, and ingestion infrastructure capable of operating at internet scale while balancing coverage, freshness, resource efficiency, and reliability. You will work on systems that process billions of URLs, manage high-throughput data flows, and ensure that high-quality content is consistently available to downstream indexing and retrieval systems. /ppbIn this position, your responsibility will be to: /b /pulliDesign, implement, and operate web-scale crawling systems for acquiring content from the internet /liliBuild ingestion workflows for internal and external data sources, including crawlers, structured feeds, and partner integrations /liliDevelop crawl scheduling, prioritisation, recrawl policies, and freshness strategies /liliBuild systems for URL discovery, deduplication, content extraction, and crawl orchestration /liliEnsure reliable operation of crawling infrastructure under high-throughput conditions /liliDefine observability and quality metrics for crawl coverage, freshness, throughput, and content quality /liliMonitor resource usage, bandwidth consumption, and infrastructure cost /liliCollaborate with indexing and ML teams to ensure acquired content meets retrieval and ranking requirements /liliEnable safe experimentation with crawling strategies and content acquisition policies /li /ulpbYou may be a good fit if you: /b /pulli5+ years of experience building backend or distributed systems /liliStrong Go or C++ expertise /liliExperience with large-scale distributed systems (10k+ RPS, billions of URLs, high-throughput pipelines) /liliUnderstanding of web protocols (HTTP, DNS, TLS), crawling, scraping, and content extraction /liliExperience operating production systems and debugging failures in distributed environments /liliStrong understanding of scalability, fault tolerance, and resource management /li /ulpbStrong candidates may also have experience with: /b /pulliWeb crawling /liliBuilding streaming data pipelines and event-driven systems /liliKafka, Pulsar, NATS, RabbitMQ, or similar messaging platforms /liliDesigning distributed schedulers, queues, and asynchronous processing systems /liliSpark, Flink, Beam, or MapReduce /liliAd tech, social networks, search engines, or other large-scale content platforms /li /ulpWe conduct coding interviews as part of the process. /ppbBenefits Perks: /b /pulliCompetitive compensation /liliCareer growth and learning opportunities /liliFlexibility and ownership /liliCollaborative and innovative culture /liliOpportunity to work on impactful AI projects /liliInternational environment and talented teams /li /ulpbWhat's it like to work at Nebius: /b /ppFast moving- Bold thinking- Constant growth- Meaningful impact- Trust and real ownership- Opportunity to shape the future of AI /ppbEqual Opportunity Statement: /b /ppNebius is an equal opportunity employer.
