## Job description

## 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

We're looking for a Recruiter to build our talent engine from the ground up and help us rapidly scale our technical talent this year. This is a rare opportunity to define the DNA of depthfirst during our most critical growth phase: shaping not just who we hire, but how we hire, what our culture becomes, and what it means to be a world-class security AI company. You'll own full-cycle recruiting for engineering and/or GTM roles, partner directly with founders and hiring managers on hiring strategy, and design the end-to-end recruiting process that will carry us through our next stage of growth. This role has the potential to grow into Head of Talent as we scale.

You're excited about this role because you will…

- Own and build full-cycle recruiting for engineering and technical roles, managing multiple searches simultaneously
- Partner directly with founders and hiring managers to define role requirements, ideal candidate profiles, and inform compensation strategy
- Build our recruiting strategy from scratch: defining our sourcing approach, candidate evaluation frameworks, and competitive positioning in the market that maintains a high bar as we scale
- Source proactively and creatively: building pipelines through direct outreach, technical communities, referrals, and other channels
- Help build our employer brand and recruiting narrative, helping candidates understand why depthfirst is the most compelling place to build the future of autonomous security

## Qualifications

- 5-7+ years of full-cycle technical recruiting experience, ideally at high-growth startups
- Proven track record of hiring exceptional engineering talent in competitive markets
- Deep understanding of technical roles: you can speak credibly about backend systems, ML infrastructure, and security engineering
- Experience building recruiting functions from scratch (0→1) or being an early recruiting hire
- High ownership mentality and comfort with ambiguity: you thrive in fast-moving environments
- Mission-driven and genuinely excited about AI and security
- Located in or willing to relocate to San Francisco (this role is in-office)

## What We Offer

- Competitive salary with meaningful equity
- Health, vision, and dental insurance
- Office lunch and dinner (SF office)
- High ownership and impact: you'll define how we hire and who we become as a company
- The opportunity to join a rapidly scaling AI startup during its most formative phase

## About DepthFirst

## Company Overview
- **One-liner**: Autonomous security platform that uses AI to continuously find, validate, and fix exploitable vulnerabilities across code, infrastructure, dependencies, and runtime environments.
- **Entity Type**: Private (Series B, $80M total funding)
- **Headquarters**: San Francisco, California, United States
- **Founded**: Not publicly available
- **Founders**: Qasim Mithani, Daniele Perito, Andrea Michi

## Core Business
- **Primary industry**: Cybersecurity (AI-native autonomous security)
- **Target customers**: B2B, Enterprise (developers, security teams, CISOs)
- **Mission or purpose statement**: "Secure the world’s most important software."

## Products & Services
- **Agentic Pentesting**: Autonomous penetration testing that runs dynamic exploits against running applications to confirm real attack paths.
- **Supply Chain Security**: Traces risk through full dependency trees and surfaces only vulnerabilities with a real execution path.
- **Secrets & Sensitive Data**: Detects and validates credentials across codebase, CI/CD pipelines, and runtime environments.
- **Code Security**: Finds vulnerabilities by tracing business logic, data flows, and cross-service interactions across the codebase.
- **Dependency Firewall**: Detects and blocks malicious behavior before it spreads in the environment.
- **Fix & Verify**: Generates merge-ready pull requests for every confirmed vulnerability, then replays the attack post-fix to ensure the vulnerability is truly resolved.

## Market Standing
- **Valuation**: Not disclosed (private company)
- **Key Metric**: Total funding $80M (Series B announced March 2026, led by Meritech Capital Partners; Series A with 12 investors)
- **Notable Investors/Partners**: Meritech Capital Partners (lead Series B), plus 12 Series A investors. Backed by leading investors in AI, security, and software.
- **Growth Signals**: 33 employees (366.7% YoY growth); 11 active job postings; claims 8x more true positives and 95% fewer false positives vs. leading tools; 90% of fixes accepted by developers; $5M in platform credits offered to open source maintainers via the Open Defense Initiative.

## Competitive Advantages
- **AI-native context-aware reasoning** – The platform understands code, business logic, and infrastructure to find complex vulnerabilities (including business logic flaws and chained exploits) that siloed tools miss.
- **Extremely low false positives and high fix acceptance** – 95% false positive reduction and 90% developer-accepted fixes create trust and productivity.
- **Founding team** – Built security at Cash App/Faire, infrastructure at AWS/Databricks, and AI research at Google DeepMind (contributions to Gemini, AlphaDev, Nature publications).
- **Continuous autonomous verification** – After each fix, the same attack is replayed in the running application; vulnerabilities are only closed when exploitation fails, not when code changes.

## Strategic Focus
- Advancing AI agents for security through reinforcement learning (training vulnerability discovery agents, e.g., dfs-mini1 model).
- Scaling enterprise adoption and expanding the Open Defense Initiative to secure widely deployed open source projects.
- Building a research-driven applied AI lab focused on software security.

## Why Work Here
- **Culture**: Positioned as an "applied AI lab" at the frontier of security and AI research. Team members come from top companies like Databricks, Meta, Google DeepMind, Faire, and Notion.
- **Work policy**: On-site in San Francisco (multiple offices, including 250 Montgomery St and 1 Sutter St).
- **Open roles**: 11 positions across Engineering (Backend, Product, Security, Research), Sales (Account Executive, SDR, Solutions Engineer), Product Design, and Business Operations.
- **Notable perks**: Not explicitly detailed but typical for well-funded Series B startups; equity, competitive compensation, and the chance to work on cutting-edge autonomous security in a rapidly growing team.
