Security Engineer (Full Remote - Croatia)
EverAI, Croatia
The 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.
The team
We are an enthusiastic, passionate and hardworking team of ≈ 100 people. Our founding team has strong entrepreneurial experience building and scaling web products from 0 to IPO.
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 fixedAudits and pentests: you’ve coordinated an external audit or pentest and followed the findings through to fixesEngineering 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 peopleAI in your daily work: you use AI tools every day in your security workA 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.Soft skills
