About the role
- Security operations centers are stuck doing work that shouldn't need a human at all, and most AI added to the SOC so far hasn't closed that gap.
- As Principal Security Engineer, you'll decide where AI can reliably take over detection, investigation, and response, and where it still needs a human in the loop.
- You'll shape platform strategy across cloud and enterprise environments, then work directly with customers as they rebuild their security operations around it.
Responsibilities
- Lead our AI cybersecurity defense work, including incident response strategy, detection engineering, automated response, threat hunting, threat research, and security automation.
- Collaborate with product, engineering, and research teams to shape the platform roadmap and our AI security solutions.
- Build and automate realistic attack simulations, adversary emulation scenarios, and large-scale security environments.
- Provide technical leadership and mentorship on security best practices, automation design, and incident response methodology.
Requirements
- Hands-on coding experience with Python or similar languages.
- Strong understanding of security concepts across endpoint, identity, cloud, and networking.
Nice to have
- 7AI is the foundational AI security company.
- Our platform pairs a federated SIEM with AI agents that detect, investigate, respond, and hunt, plus dedicated threat hunting and threat intelligence, with humans on the loop.
- That's the appeal:
- you'll join at a pivotal stage where your work shapes what 7AI becomes, alongside security veterans who've built this before.
Company info
- Founded in 2024 by Cybereason co-founders Lior Div and Yonatan Striem-Amit, we came out of stealth in February 2025 to take on the non-human work of the SOC.

- Work directly with customers, understand their security posture and processes, and guide their AI security transformation.
- Experience collaborating directly with customers.
