Backend Engineer

Title: Backend Engineer
Location: San Jose · Hybrid
Duration: Full-Time Permanent

Seed-stage · Enterprise Security · AI Agents

AI agents are starting to take real actions inside companies — calling APIs, touching production data, executing workflows. Security teams have no way to see what theyre doing, let alone control it. Were building the runtime that sits between agents and the systems they touch — and helping define a new category in the process.

What youll build
Youll own a major surface area from day one
The entity graph — a real-time model of every user, agent, resource, and action across a customers environment
The integrations layer that keeps it in sync with Okta, AWS, and the rest of the identity and cloud stack
The policy and audit APIs that decide, in milliseconds, whether an agent gets to make a call — and prove it later
A policy engine is only as good as the world model it reasons over, so were building both. Your code ships to paying customers, not a demo.

You
Have built and operated backend systems that real customers depended on
Strong in Go or Python or Java
Comfortable designing data models under ambiguity — graph experience is a plus
Turn vague problems into simple, reliable systems
Bonus
background in security, identity, or infrastructure; experience with agents or tool-calling systems.

Roles and responsibilities
Build the runtime that sits between AI agents and the systems they touch. Own a major surface area from day one, including the entity graph, the integrations layer with Okta, AWS, and the cloud stack, and the policy and audit APIs. Build both a policy engine and a world model it reasons over. Ship code to paying customers.
