Security Analyst - Tier 3 (West Coast)

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, were building the AI foundation for security operations in the agentic era, and were still early. Thats the appeal: youll join at a pivotal stage where your work shapes what 7AI becomes, alongside security veterans whove 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

7AIs AI agents take on a lot of the SOCs 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, youll be the technical lead and escalation point for junior analysts reviewing 7AIs AI agent investigations. Youll validate the agents work, prove out the threats they stopped, and help customers understand the risk that was prevented. Youll also hunt for malicious activity in customer environments using 7AIs agents, and help build the processes that let this team scale without losing quality.

What Youll Do

• Serve as the technical escalation point for junior analysts and mentor them

• Correlate data across cloud, endpoint, identity, and network sources to build the full picture of an attack

• Investigate malicious activity the AI agents responded to, and assess the risk that was prevented for customers

• Use 7AIs AI agents to hunt for emerging threats in customer environments, feeding new detections back into the product
