About depthfirst
We believe that software is the foundation of modern civilization. Yet vulnerabilities threaten its integrity, security, and resilience. We are on a mission to secure the world's software.
depthfirst is building intelligence to detect and remediate critical software vulnerabilities. We are training and scaling security AI agents to discover zero-days vulnerabilities across large customer codebases and popular open source software.
Our founding team includes deep expertise in data, infrastructure, security and LLMs with technical leaders from DeepMind, Databricks, Square, and Faire. We are looking for strong technical people who are interested in working at the intersection of AI, Security, and Infrastructure.
About This Role
We're looking for a Security Product Engineer to work directly with customers to deploy and operationalize depthfirst's security AI agents in their environments. You'll be the technical bridge between our product and enterprise security infrastructure, ensuring our AI successfully detects vulnerabilities at scale.
You'll embed with customers to understand their security challenges, build custom integrations on top of depthfirst's platform, and partner closely with our product team to generalize solutions. This role combines hands-on engineering with deep customer collaboration—you'll shape both how customers use depthfirst and how our product evolves.
