Security Researcher

“What we do in life echoes in eternity.”

If you’re looking for meaningful work, real influence, and the opportunity to become a key part of an ambitious startup, Deune is the place for you.

Deune is an AI cybersecurity startup with a proprietary approach to vulnerability discovery, making systems more secure, controlled, and verifiable. We’ve raised our friends and family round, have three patents pending, and are now building our core team.

When you’re building something serious, you want people you trust beside you.

We’re looking for an exceptional Security Researcher to join as an early member of our team.

We’re looking for someone with deep hands on experience in vulnerability research, source code auditing, exploitation, and offensive security, combined with strong software development skills and experience building or working with AI and agentic systems.

The role will involve researching and developing revolutionary approaches to software security, combining hands on vulnerability research with the development of agentic security systems, analyzing complex codebases and attack surfaces, building PoCs, and developing new research ideas into scalable tools and production capabilities.

We’re looking for someone who can think like a security researcher and build like an engineer.

This isn’t just another security research job. It’s an opportunity to shape the technology, influence the company’s direction, play a meaningful role from the earliest stage, and have the greatest opportunity to benefit from the ESOP and the long-term value we create together.

If you want to build something meaningful, solve difficult technical problems, take real ownership, and join a startup where your voice will truly matter, apply or DM us.

And if this isn’t for you, but someone exceptional comes to mind, please connect us.
