We are seeking a Principal AI – Large Language Model (LLM) Expert to lead the design, training, optimization, and deployment of language models across our privacy‑first security platform. This role combines deep research expertise with hands‑on engineering, spanning foundation model development, task‑specific fine‑tuning, and efficient Small Language Model (SLM) deployment in privacy‑sensitive, resource‑constrained environments.

You will bridge cutting‑edge LLM research with privacy‑preserving constraints and real‑world security requirements, owning architectural decisions, data strategy, evaluation rigor, and performance optimization from lab to production. As a founding technical leader, you'll shape how we embed LLMs into detection, classification, and response workflows without compromising user privacy or security posture.
