## Job description

## About depthfirst

Software is the foundation of modern civilization, yet vulnerabilities threaten its integrity, security, and resilience. depthfirst is on a mission to secure the world’s software. We are building intelligent security agents that detect and remediate critical vulnerabilities across large customer codebases and widely used open-source software. Our founding team brings deep expertise in AI, security, data, and infrastructure, 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.

## The Role

As a Designer, you’ll help shape both how depthfirst’s products work and how the company shows up in the world. This is a flexible role for someone whose strengths may lean toward product, brand, or span both. We do not expect every candidate to have equal experience across every area. We care most about exceptional craft, strong judgment, and the ability to apply both to ambitious, unfamiliar problems. Depending on your strengths and interests, you may design core product experiences, create brand and marketing work, or move between the two. On the product side, you’ll work closely with engineers, product, and AI researchers to make complex security systems intuitive, trustworthy, and powerful. On the brand side, you’ll translate technical ideas into clear, compelling stories across launches, campaigns, events, and customer touch points. This is a hands-on role with meaningful ownership. You’ll help define what we build, how we communicate it, and how our design language evolves as the company grows.

## What You’ll Do

- Design product experiences from ambiguous problem brief through polished execution, that help people understand, investigate, and act on complex code security, transparency systems, and knowledge work.
- Translate complex ideas in AI and security into experiences and narratives that feel clear, engaging, and approachable.
- Create brand work across our website, product launches, campaigns, sales materials, events, editorial content, company storytelling, and out-of-home advertising.
- Build and evolve shared product and brand systems that help the company move quickly without sacrificing quality.
- Prototype and iterate on ideas at the level of fidelity needed to make good decisions.
- Collaborate closely with design, engineering, product, research, marketing, go-to-market as applicable.
- Contribute beyond your primary discipline when a project benefits from it, with support from the broader design team.

## What We’re Looking For

Minimum qualifications:

- A portfolio demonstrating exceptional craft and thoughtful problem-solving in product design, brand design, or both.
- Strong visual design fundamentals and close attention to detail.
- The ability to turn complex or technical ideas into clear, intuitive experiences or compelling visual stories.
- A high level of ownership and comfort working through ambiguity.
- Strong collaboration and communication.

Preferred qualifications. We encourage you to apply if you meet some, but not all, of these:

- 4+ years of experience in product, brand, visual, interaction, marketing, or multidisciplinary design. Level and scope can flex based on experience.
- Experience designing AI products, technical tools, or other novel systems where established patterns do not yet exist.
- Experience contributing to a design system, component library, or scalable brand system.
- The ability to prototype in code to accelerate design and development workflows.
- Experience creating work across websites, launches, campaigns, editorial content, events, or customer-facing materials.
- A track record of raising the bar for quality, clarity, and craft.

## Why Join

Software security is one of the defining technical challenges of our time. At depthfirst, you’ll help shape a company tackling that challenge at the frontier of AI security, protecting the AI systems being built every day. You’ll join early enough to influence both what we build and how we present it to the world. Rather than following an established playbook, you’ll help create it with support from the broader design team.

## What We Offer

- Competitive salary with meaningful equity
- Health, vision, and dental insurance
- Office lunch and dinner when working from our San Francisco office

## 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.
