Job description
Beyond research, the team designs and implements detection mechanisms and translates these defenses into shipping products across endpoint, cloud, and standalone form factors.

Research attacks against conversational AI systems — exploring, probing, and breaking them to discover vulnerabilities before adversaries do.
Design and propose mitigations, protections, and detection strategies based on findings from adversarial research.
Build a multilayered detection core, combining different approaches to identify malicious prompts and attempts to manipulate AI systems.
Productize detection capabilities — packaging and deploying them across endpoint, cloud, and standalone environments.
Collaborate with the broader threat detection department, product teams, and endpoint teams to integrate defenses into shipping security solutions.
Evaluate and experiment with open-source and proprietary AI tooling to stay current with the rapidly evolving attack surface.
Shape the team's technical direction and methodology as a founding member, with the opportunity to grow into a Team Lead role over time.
