Job description

Description

OX Security is securing the AI-driven SDLC from prompt to production. We’re building the next generation of security technology for a world where AI is changing how software is built, deployed, and attacked.

We’re looking for a strong Senior Backend Engineer to join VIBESEC, the team building our AI security products. This is one of the most exciting places to be at OX right now: a brand new product, in a domain that changes every single day, with real customers already shaping what we build next.

You’ll join a small, senior, globally distributed team of six engineers across Europe, Israel and Argentina. You’ll own features end to end, from the first conversation with Product through design, build and production. Because the domain is new, your technical judgment will shape the architecture rather than follow it.

If you want to build something genuinely new, at the point where AI and security meet, let’s talk.

Requirements:
