Six kinds of employer
Every company in the directory below had AI security postings when we checked in November 2026, and they fall into six families. Frontier labs secure their own models, agents and infrastructure and run red teams against them. Big tech companies run AI red teams and product security for AI features at very large scale. Security vendors build AI security products. AI security startups red-team and protect models and agents for customers. Data platforms and enterprises secure their own AI adoption. Government bodies such as the UK AI Security Institute evaluate frontier models.
The family predicts the interview better than the company's size, because it decides whether you will be securing a system, building a product or advising on risk.
The titles to search
Searching for AI Security Engineer alone misses most of the market. Microsoft titles its AI red teamers AI Security Researcher or AI Security and Safety Researcher. Google DeepMind uses Agentic Red Team as a team name. Anthropic splits the work between its Safeguards red team and Security Engineering, and Google posts AI Protection roles. Vendors post researcher and engineer roles on named products, such as the Prisma AIRS red teaming team at Palo Alto Networks.
Acquisitions reshaping the market
Many of the first AI security startups now sit inside larger security companies. Cisco acquired Robust Intelligence in 2024. In 2025, Palo Alto Networks acquired Protect AI, Check Point acquired Lakera, SentinelOne acquired Prompt Security, CrowdStrike acquired Pangea and F5 acquired CalypsoAI. Google completed its acquisition of Wiz in March 2026, and in November 2026 CrowdStrike announced agreements to acquire Fiddler AI and Dreadnode.
For a job seeker, this means the teams behind well-known AI security products are often hiring through the acquirer's careers site, under the acquirer's titles.
Outside the United States
London has the densest cluster outside the US: Anthropic, the UK AI Security Institute, Mindgard and teams at several labs. Zurich hosts Anthropic and Google DeepMind security roles and Check Point's AI security centre built on Lakera. Paris has Mistral AI's security team. In India, the postings we found came mainly from services firms and global banks' technology centres, with little first-party pay data.
