Tech Lead, Hexagate

The engineering team at Chainalysis is inspired by solving the hardest technical challenges and creating products that build trust in cryptocurrencies. We’re a global organization with teams in Denmark, UK, Canada, the USA, and Israel who thrive on the challenging work we do and doing it with other exceptionally talented teammates. Our industry changes every day and our job is to create user facing products supported by a flexible and scalable data platform allowing us to adapt to those rapid changes and bring value to our customers. 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 About Chainalysis Blockchain technology is powering a growing wave of innovation.
