Tech Lead, 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 Tech Lead to join the 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 LEAD AND BUILD - Technical leadership: set direction for a core area (pipelines, detection platform, response, or LLM systems). Own architecture, roadmap execution, and technical quality. - Real-time pipelines: lead designs for high-throughput ingestion, normalization, enrichment, and routing of multi-chain activity. - Detection platform: evolve detection engines across our monitoring DSL, statistical/anomaly models, ML models, and threat intelligence. - Operational excellence: define standards for reliability and observability. Drive incident learnings, performance work, and production health. - Team impact: mentor engineers, run design reviews, unblock delivery, and raise the quality bar. WE'RE LOOKING FOR CANDIDATES WHO HAVE - Staff level backend engineering, with a track record of leading technical decisions in production systems. - Distributed systems depth: reliability, latency, concurrency, backpressure, idempotency. - Strong API design and data modeling skills (relational + event-driven). - Ability to lead through influence: clear communication, strong judgment, and pragmatic trade-offs. - High ownership. You drive execution end-to-end and keep systems healthy in production. YOU MIGHT ALSO HAVE - Web3/blockchain experience or strong interest. - Real-time / streaming data experience. - Security, fraud, risk, or other adversarial-domain experience. - Experience building platform capabilities used by other engineers. 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.
