Senior Software Engineer, Hexagate

The engineering team at Chainalysis is inspired by solving the hardest technical challenges and building products that establish trust in cryptocurrencies. We're a global organization that thrives on challenging work and doing it alongside exceptionally talented teammates. Our industry evolves rapidly, and our mission is to build a flexible, AI-driven platform that automates entity resolution, optimizes data labeling pipelines, and creates predictive models that identify illicit patterns before they escalate. Our data and solutions have been used to solve some of the world's most high-profile criminal cases and grow consumer access to cryptocurrency safely. Now, by pairing the industry's most trusted blockchain data with agents that reason, investigate, and act, we help our customers scale their workflows as the cryptocurrency economy becomes increasingly mainstream. We're currently looking for a Senior Software Engineer to join our Hexagate team. Hexagate builds cybersecurity products that protect on-chain and web3 assets. We sit at the intersection of cybersecurity and blockchains—an adversarial space where attacks are constant and response time matters. We’re building a real-time on-chain detection and response platform that combines ML-driven threat intelligence, custom detections, and an LLM-powered rules engine to protect on-chain assets. What you'll build : Real-time pipelines: ingest, normalize, enrich, and route multi-chain activity at high throughput. Detection engines: Our internal monitoring language (DSL), statistical/anomaly models, ML models, and threat intelligence Response workflows: turn detections into alerts, automations, and integrations (webhooks/SIEM). LLM systems: help users translate intent into monitors/workflows and speed up investigations—safely and predictably. Production ownership: design → build → deploy → operate. Improve observability, latency, and reliability. We’re looking for candidates who have: Senior backend experience. You’ve
