About the role
- Our customers in defense, aerospace and more trust us with sensitive systems requirements. That means security is a first-order part of the product, so we're looking for a Staff Software Engineer to own it.
- This is our first dedicated security hire, so you'll define the security architecture, harden the platform, and build out the compliance posture. Since LLMs and agentic workflows sit at the center of what we do, you'll also lead how we secure them.

Responsibilities
- Own security architecture across the platform: threat modeling, secure design reviews, and the standards we build against.
- Build the security tooling we need across detection, monitoring, vulnerability management, and CI/CD.
- 8+ years building production software, including running secure services at scale in the cloud.
- You're comfortable being the security lead at a startup and setting the agenda yourself.
Nice to have
- You've owned security in a regulated or high-trust environment and have implemented SOC 2 yourself.
- Export control, ITAR, or FedRAMP experience is a big plus.
- Solid on threat modeling, secure architecture, and incident response.
- You've secured AI or LLM systems.
- TypeScript/Node.js and Python for AI and backend services.
- Postgres and other managed cloud services for data and state.
Compensation
