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
Lead high‑priority, cross‑functional projects that don't sit neatly in one department such as competitive analysis, AI automation efforts, and ad‑hoc analyses
Own the company's operating cadence: leadership meetings, all‑hands, planning cycles and keep cross‑functional initiatives on track
Develop integrated views of product economics, market dynamics, and business performance that no single function owns, driving alignment and decision making that span Product, Eng, Finance, and GTM
Act as an extension of the CEO in communication with functional leads, customers, board members, and investors
Qualifications
5+ years of experience in a mix of strategy consulting, banking/PE, or an operating role (GM, biz ops, or functional lead) at a scaling startup
Bachelor's Degree from a top university
Direct startup experience is strongly preferred
Comfort navigating ambiguity and building credibility with functional peers
Speaks the language of Eng, Finance, and GTM well enough that each trusts your judgment as an extension of their own
Demonstrated ability to work through unstructured problems and drive them to outcomes independently
Strong written and verbal communication
Ability to move fluidly between strategic thinking and tactical execution in the same day
High judgment and discretion, given regular access to sensitive company information
Bonus Points For
Experience at a high‑growth startup or early‑stage company
Hands‑on experience with AI tools, agents, or automation to increase analytical and operational velocity
Familiarity with security, infrastructure, or developer tooling markets
What We Offer
Competitive salary with meaningful equity
Health, vision, and dental insurance
401k
Office lunch and dinner (SF office)
Ownership and significant room to grow as the company scales
