## About the Role

3+ years at high-growth companies, strong distributed systems and cloud experience, a real sense of ownership, first-principles thinking, and a willingness to implement gnarly business logic (elegantly, ideally) if it makes a jaded security engineer's life easier. Kubernetes and security knowledge are nice to have, not required. You're in the Bay Area and want to be in the office five days a week.

## Description

* A near-real-time, self-updating map of an environment so you can see an attack as it happens, plus "time travel" in the graph so you can replay it afterward.
 * Teaching an agent to answer questions about a large graph quickly, with only the context it needs and without making mistakes.
 * Determining who owns a given resource from messy signals like tags, actions, logs, and files.

Stack: Cartography for ingestion, Neo4j for the graph, Python/FastAPI backend, Svelte frontend with a homegrown WebGL graph renderer, an MCP server that exposes all of it to agents, Terraform for IaC.
