Senior Software Engineer, Hexagate

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.

Responsibilities

• Build real-time pipelines to ingest, normalize, enrich, and route multi-chain activity at high throughput
• Develop detection engines including internal monitoring DSL, statistical and anomaly models, ML models, and threat intelligence
• Design response workflows that turn detections into alerts, automations, and integrations (webhooks/SIEM)
• Build LLM systems that translate user intent into monitors and workflows
• Own production systems end-to-end: design, build, deploy, and operate
• Improve observability, latency, and reliability

Requirements

• Senior backend experience shipping and operating production services
• Distributed systems experience: reliability, latency, concurrency, backpressure, and idempotency
• Strong API design and data modeling skills (relational + event-driven)
• High ownership and ability to drive work end-to-end
• Strong collaboration and communication skills
• Web3/blockchain experience or interest is a plus
• Real-time or streaming data experience is a plus
• Security or fraud domain experience is a plus
