Careers
Build the gate that tells an agent no
Deixic sits between AI agents and the systems they call: each action runs, waits for a human, or is denied, and the decision is recorded. 4 open roles build that path, all in San Francisco, in person.
Agent Runtime Engineer
Ship the paths that decide whether an agent action runs, waits on a human, or is denied—under load.
Forward-Deployed Engineer
Get customers live on agent cost, status, and approvals; embed only when production paths still live in tribal knowledge.
Security Engineer
Own identity, scope, and incident response for agents that act on company systems.
Eval Engineer
Build tests that prove agent controls still work when something tries to break them.
How we work
Built with the agents it governs
The agents work here too
Coding agents build the product behind the same gates it sells. The blog documents the factory: Keeping a software factory alive.
Rust on the hot path
The kernel that gates agent actions is Rust — agents wrote most of the rewrite PRs, and we wrote up why Rust over Go.

His second security company — the first, ThreatKey, was acquired. Before that: Carta, Snap. You would join at the start.
