Skills
About the Role
You'll join the Hexagate team to build cybersecurity products that protect on-chain and web3 assets, working in an adversarial space where attacks are constant and response time matters. You will build real-time pipelines that ingest, normalize, enrich, and route multi-chain activity at high throughput. You'll work on detection engines including an internal monitoring DSL, statistical and anomaly models, ML models, and threat intelligence. You'll design response workflows that turn detections into alerts, automations, and integrations like webhooks and SIEM. You'll also work on LLM systems that help users translate intent into monitors and workflows and speed up investigations safely and predictably. You'll own production systems end-to-end, from design through build, deploy, and operation, continuously improving observability, latency, and reliability.
Requirements
- Senior backend experience shipping and operating production services
