Job description

About 7AI

7AI is the foundational AI security company. 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. 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.

Backed by $166 million in total funding from investors including Index Ventures and Blackstone, we’re building the AI foundation for security operations in the agentic era, and we’re still early. 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. Our culture runs on respect, collaboration, and a shared bar for excellence, all pointed at one goal, delivering real outcomes for the customers who trust us to defend them.

Overview

7AI’s AI agents take on a lot of the SOC’s non-human work, but scaling that trust requires senior analysts who can validate the hardest cases and mentor the team doing it. As a Tier 3 Security Analyst, you’ll be the technical lead and escalation point for junior analysts reviewing 7AI’s AI agent investigations. You’ll validate the agents’ work, prove out the threats they stopped, and help customers understand the risk that was prevented. You’ll also hunt for malicious activity in customer environments using 7AI’s agents, and help build the processes that let this team scale without losing quality.

• Strong understanding of security monitoring tools such as XDR, SIEM, IDS/IPS, and IDP

• Familiarity with log and telemetry concepts

• Strong knowledge of common attack techniques and frameworks such as MITRE ATT&CK, and incident triage methodologies

• Strong analytical and problem-solving skills, with the ability to verify AI-driven analysis and make independent security decisions

• Data querying experience with SIEM query languages such as SPL, KQL, FQL, or SQL

• Strong knowledge of malware analysis methods

• Strong interpersonal skills and a service-oriented mindset

• A track record of collaborating well on a team, including mentoring others and teaching complex concepts
