Chief of Staff, CEO

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-day vulnerabilities across large customer codebases and popular open source software.

Our founding team brings deep expertise in data, infrastructure, security and AI, with leaders from DeepMind, Databricks, Square, and Faire. We're looking for thoughtful, driven people excited to work at the intersection of AI, Security, and Infrastructure.

About This Role

As Chief of Staff to the CEO, you'll operate at the center of the company working directly with the CEO and executive team as the company scales through one of the most important growth phases of the company. You'll act as a leverage point for the CEO, turning strategy into execution, running the initiatives that don't have a natural home in one function, owning the hardest cross-functional problems, driving the highest-stakes decisions, and ensuring leadership operates with clarity and speed.

Some days you'll be driving company-wide initiatives. Other days you'll be preparing board materials, leading strategic analyses, solving organizational bottlenecks, or jumping into customer conversations.

This is a high-trust, high-visibility role for someone who wants broad exposure to how a fast-growing AI security company is actually built and run.

You're excited about this role because you will…

Act as a trusted advisor and extension of the CEO, turning priorities into structured plans (OKRs, board materials, investor updates, decision memos), and proactively close gaps, see around corners, and resolve problems before they reach the CEO's desk

Act as an extension of the CEO in communication with functional leads, customers, board members, and investors
