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.

Own security architecture across the platform: threat modeling, secure design reviews, and the standards we build against.

Harden the full stack, from application security to cloud infrastructure (identity, network, secrets), tenant isolation, and data protection.

Drive SOC 2 and get us ready for the certifications defense and aerospace customers ask about, including export control and ITAR.

Secure our AI and agentic systems: prompt injection, data leaking through models, what actions agents are allowed to take, and guardrails.

Build the security tooling we need across detection, monitoring, vulnerability management, and CI/CD.

Stand up incident response and run it, from detection through postmortems.

Work with sales and product to get through security reviews and win customer confidence.
