Principal AI – Large Language Models

Lead and manage the design development, and deployment of large language models (LLMs) across our privacy‑first security platform. Responsible for driving end‑to‑end LLM research, engineering, and operational deployment, ensuring model performance, privacy compliance, and real‑world security impact. This role combines technical leadership, hands‑on engineering, and cross‑functional collaboration to integrate LLMs into detection, classification, and response workflows.Key ResponsibilitiesLead the research, design, and implementation of Transformer‑based architectures (BERT, GPT, T5, LLaMA, etc.) optimized for security tasks.Evaluate architectural designs for efficiency, robustness, privacy, and security.Define threat‑detection‑specific requirements, including phishing, BEC, malware, and policy violation classification.Optimize foundation model pre‑training and distributed training strategies for compute efficiency.Develop parameter‑efficient fine‑tuning strategies (LoRA, adapters, prefix tuning) for downstream security tasks.Small Language Models & Edge DeploymentBuild efficient Small Language Models (SLMs) for edge or customer environments with low latency (
