Security Analyst - Tier 3

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 Agent investigations. You'll validate the agents' work, prove out the threats they stopped, and hunt for malicious activity across customer environments. You'll also help build the processes that let this team scale without losing quality.

What You’ll Do:

Analyze and validate investigations completed by the AI Agents for accuracy and completeness, evaluating risk

Lead and mentor junior analysts and serve as the technical expert and key escalation point for investigations

Correlate data from various data sources including cloud, endpoint, identity, network, etc. to understand that full picture of a malicious activity

Investigate malicious activity that the 7AI Agents responded to and understand the complexity of the attack that was stopped including the risk that was prevented for customers

Use our advanced AI Agents to hunt in customer environments to detect and remediate emerging threats, ultimately contributing to detections that will be folded back into the product

Assist customers with ongoing threat monitoring, triage, and prioritization of security alerts as needed but especially during incidents to resolve threats and secure the environment

Proactively identify potential threats and anomalies in customer environments by reviewing logs and malicious findings

Utilize your supreme communication skills to engage with customers who vary in their level of technical depth and focus (from SOC analysts to CISOs)

Architect processes while we build out this elite organization to scale the operation sustainably while maintaining consistent quality

Collaborate with the Sales, Engineering, and Product teams, providing feedback on the customer experience and assist in optimizing and tuning the AI platform

Stay current with emerging cybersecurity trends, vulnerabilities, and new attack techniques, especially the field of AI-driven attacks

What We're Looking For:

5+ years of experience in cyber security operations

Hands-on experience with investigating alerts and across multiple sources (endpoint, network, identity, email, cloud, etc.)

Strong understanding of security monitoring tools (XDR, SIEM, IDS/IPS, IDP, etc.)

Familiarity with log \ telemetry concepts

Experience analyzing and investigating security alerts from multiple sources, including intrusion detection systems, network monitoring tools, and endpoint protection platforms

Strong knowledge of common attack techniques and frameworks (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 querying technologies (SPL, KQL, FQL, SQL, etc) and familiarity with log / telemetry concepts

Strong knowledge with Malware Analysis methods

Great interpersonal skills with a service oriented mindset

Proven track record of successfully collaborating in a team, including mentorship skills and ability to teach complex concepts

Nice to Have:

Prior experience in a Managed Services environment

Incident Handling experience
