Key Responsibilities

Example projects

Extend the scope of one of our detectors to support multiple languages without dropping performance on already supported languages.

Increase the scope where our defenses perform by 100x (e.g., multi-lingual data, code, etc).

-
Extend modeling and data generation to enable passing additional context to our prompt injection detectors, such as the LLM output and behavioral metadata.

-
Red team our model to understand the most pressing vulnerabilities of our detectors and prioritize the data collection and generation required to fix them.

-
You have had experience working on end-to-end development of ML models.
