Senior Software Engineer, Hexagate

Job description

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 shipped and operated production services. - Distributed systems experience: reliability, latency, concurrency, backpressure, and idempotency. - Strong API design and data modeling skills (relational + event-driven). - High ownership. You drive work end-to-end and care about outcomes. - Strong collaboration. You communicate clearly and raise the quality bar. You might also have: - Web3/blockchain experience/ interest.. - Real-time / streaming data experience. - Security or fraud domain experience. Technologies we use: - Languages: Python, Rust, Go - Infra: Kubernetes, AWS, Grafana, Pulumi - Streaming & Messaging: NATS - Data stores: PostgreSQL, Redis, S3 AI at Chainalysis AI is not a feature at Chainalysis - it is a new way of working. One that turns instructions into work done, and helps us move faster than the threats we're built to counter, and we expect our employees to take ownership of the output and ensure quality. As the world's most trusted blockchain analytics platform, Chainalysis sits at a rare intersection of proprietary data, regulatory relationships and crypto expertise that makes it uniquely placed to shape and lead the next era of AI-driven intelligence - and we expect everyone here, regardless of role, to be an active part of it. AI fluency is tied directly to how we measure performance and how we plan to win. There is no substitute for your own curiosity. We provide the tools, workflows, and space to experiment - but the expectation is that you develop these capabilities yourself, bring ideas, and collaborate across teams to reinvent the way work gets done. We are not using AI to do less. We are using it to do what was never possible before. About Chainalysis Chainalysis is the blockchain data platform, making it easy to connect the movement of digital assets to real-world services.
