Wix makes it possible for anyone to succeed online. Since 2006, we’ve grown to around 4,400 employees in 22 countries, launched over 40 products, and serve over 299 million users and their visitors worldwide. At Wix, we push you to innovate and evolve in non-traditional ways. We operate in collaborative, high-performing teams, building cutting-edge products and leveraging AI to redefine how our users create, manage and grow their dreams online.

Although we’re already industry leaders in web creation and business, our work is nowhere near done. Our goal is to become the main engine of the Internet so we can create a more open web for all.

We're proud to be an equal opportunity employer. Wix was built around the idea that everyone has the right to be successful, online. This same vision defines us as an employer: creating a work environment where everyone is welcome, and anyone has the right to succeed.

Join the Wix security guild as a Security Researcher and play a key role in safeguarding our systems by leading proactive research into emerging technologies and the ever-evolving field of AI security. In your day-to-day, you will:

• Conduct proactive security research on emerging technologies, focusing on AI/ML systems, LLM security, and automated threat vectors

• Perform threat modeling, vulnerability analysis, and technical evaluations of new platforms and architectures

• Develop Proof-of-Concepts (PoCs) and lightweight research tools in Python to test security assumptions and validate vulnerabilities

• Analyze novel attack techniques, public breaches, and industry trends to identify systemic risks and mitigate them before they’re exploited

• Translate complex research, technical findings, and AI vulnerabilities into actionable security controls, strategic insights, and recommendations

• Collaborate closely with Security and Engineering teams to turn research findings into real-world security improvements

• Present research findings clearly to both technical and non-technical audiences

At Wix, we believe our best work happens together. Our work model is fully in person, with 5 days a week from our office. Flexibility remains a core value at Wix and special requests are handled thoughtfully at the team level.

• 2-4 years of hands-on experience in security research, vulnerability research, threat intelligence, or offensive security. Military/intelligence unit service, academic research, CTFs, or strong personal research projects are highly valued

• Deep understanding of core cybersecurity concepts and modern web/cloud architectures

• Hands-on experience with Python for prototyping, automation, and developing research tools or PoCs

• Familiarity with AI/ML security principles (e.g., OWASP Top 10 for LLMs, prompt injection, data poisoning, model exposure risks)

• Strong critical thinking and an offensive mindset - you question assumptions, seek root causes, and look for ways systems can fail or be exploited

• A self-starter who is organized, takes ownership of research projects end-to-end, and drives them to actionable conclusions

• Excellent written and verbal communication skills in English, with the ability to turn complex technical findings into clear conclusions
