Design and build backend services for AI security products using Node.js and TypeScript. Own features from requirements and architecture through implementation, delivery, and production quality. Collaborate with Product, Design, customers, and engineering teams; make architectural decisions in an evolving domain; and raise technical standards through reviews and design discussions. The role requires handling distributed systems, ambiguity, multiple stakeholders, and rapid product change, with AI technology adoption encouraged.
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 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.
ResponsibilitiesWhat You'll Be Doing
- Design and build the backend of our AI security products in Node.js and TypeScript, running across cloud environments and endpoints
- Own features end to end, from business requirements through architecture, implementation, delivery and production quality
- Work closely with Product and directly with customers, turning fast-moving business needs into robust technical solutions
- Partner with Product, Design, and other engineering teams on complex cross-company projects
- Make and defend architectural decisions in a domain with no established playbook, where the right answer this quarter may not be the right answer next quarter
- Set the technical bar for a senior team, and raise it through code reviews, design discussions and examples
What We're Looking For
- 6+ years of hands-on backend development experience
- Strong, production-level experience with Node.js and TypeScript (must-have)
- Proven ability to design and deliver solutions for complex, distributed systems
- Strong ownership and accountability, with high independence and the ability to manage multiple stakeholders
- A track record of taking features from requirement to production, with production-grade code
- Comfort with ambiguity and rapid change, and the judgment to know when to move fast and when to build for the long run
- Excellent English and strong communication in a fully distributed team
- The "AI-First" Spark: You are an early adopter of AI technologies and are passionate about finding ways to use AI to improve developer experience and system performance.
Bonus Points for :
- Experience with microservices architecture
- Background in cybersecurity or endpoint agent development
- Experience delivering customer-value-driven products in fast-paced startup environments
- Hands-on work with LLMs, AI agents or AI-powered product features
