About MagenAI

MagenAI is a cybersecurity startup based in Tel Aviv, protecting organizations from data leaks and security risks caused by LLM tools (ChatGPT, Gemini, Copilot, Claude, etc.).

We help enterprises monitor, control, and secure AI usage across their workforce — without slowing down productivity.

We already work with large organizations and public institutions, and we are entering a strong growth phase.

• Work directly with enterprise customers and security teams
• Contribute to fundraising activities and strategic decisions

✔️ 10+ years in cybersecurity (AppSec, cloud security, or infrastructure security)

✔️ Strong experience in cloud (AWS/GCP/Azure), containerization, and scalable architectures

✔️ Proven ability to lead engineering and ship production-ready SaaS products

✔️ Solid background in backend development (Node.js / Python / Go preferred)

✔️ Hands-on understanding of DLP, IAM, SSO, policies, enterprise security, or compliance
