This is a hands-on AppSec role: you’ll review code, find real vulnerabilities and drive fixes across the stack. You’ll be the main security person in the company, reporting directly to our CTO and Co-Founder. You’ll set direction yourself and explain risk clearly to non-security colleagues. Our product includes AI-generated content, including NSFW content, and you’ll also keep an eye on AI-specific threats like prompt injection. Real ownership from day one. This isn’t an infrastructure, networking or DevSecOps role: we’re looking for application security depth. KEY RESPONSIBILITIES APPLICATION SECURITY (THE CORE OF THE ROLE) - Review code every week to catch vulnerabilities before they ship - Find, prioritize and drive fixes for real vulnerabilities across the stack, not surface-level issues AUDITS AND PENTESTS - Coordinate external security audits and penetration tests - Challenge findings where needed, and follow them through to fixes ENGINEERING AND AUTOMATION - Automate security work and build the tools you need to scale it - Use AI tools daily in your security work: code review, pentests and scripting OWNERSHIP AND COMMUNICATION - Own security end to end with little support, and decide what matters most - Explain technical risk in plain words to the team and leadership - Cover security alerts, including occasional night and weekend on-call ALSO PART OF THE ROLE (LIGHTER) - Keep a simple risk register and GRC documentation up to date - Share security updates with the team and run awareness training - Watch emerging AI threats (prompt injection, jailbreaks, content filter bypass) and incidents at our AI providers YOUR QUALIFICATIONS MUST-HAVES - 2+ years of hands-on security experience - Hands-on AppSec, not compliance only: you review code regularly and can walk us through a real vulnerability you found and fixed - Audits and pentests: you’ve coordinated an external audit or pentest and followed the findings through to fixes - Engineering workflows: you ship code with Git/GitHub, script in Python or Bash, and have recent hands-on work on a modern web stack (e.g. Rails, Node; GCP, Heroku or similar) - Ownership with little support: you’ve been the sole or lead security person, or owned a security area on your own. You’ve reviewed code or tested systems every week in the last 2 years, and you explain risk clearly to non-technical people - AI in your daily work: you use AI tools every day in your security work - A hacker mindset: You love breaking things to make them safer, and security isn’t only your job: you do it for fun too, through bug bounties, CTFs, research, write-ups or your own tools.
