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
