Your Role

As a Security Engineer, you’ll own application security for a fast-growing AI companionship platform. 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.

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

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.

Nice-to-haves

• AI/LLM security testing (prompt injection, jailbreaking): a strong plus
• Experience at an AI company or a scale‑up
• GRC awareness
• Familiarity with MDM and access management

Soft Skills

• Strong communication & collaborative skills (perfectly fluent in English)
• Goal-orientated, ownership and commitment
• Doer mindset - we are moving fast and we need people who can find the right balance between executing, planning and strategy
• Humble - willing to learn, open to feedback
• #NSFW - you are comfortable working in an environment with products that are based on uncensored models and content
