Principal AI Engineer

TENEX.AI is an AI-native, automation-first Managed Detection and Response provider focused on enhancing cybersecurity through advanced threat detection. The Principal AI Engineer will be responsible for designing and optimizing scalable AI systems, mentoring engineering teams, and driving technical innovation in AI-driven cybersecurity solutions.

Responsibilities:

• Design & build the AI layer that powers autonomous detection, RAG-backed investigation, and auto-remediation workflows
• Develop and productionize large-scale LLMs, graph-based reasoning engines, and streaming feature pipelines that operate on billions of security events
• Own evaluation & reliability—from prompt libraries and fine tuning to red-team testing, latency budgets, and fallback strategies
• Mentor & grow a cohort of AI engineers; run design reviews, uphold code quality, and instill a security-first mindset
• Partner tightly with Product, Detection Engineering, and Customer Success to translate real-world attacker behavior into robust ML and rule-based detections
• Push the frontier—experiment with retrieval-augmented generation, tool-calling agents, and multi-modal models (text + logs + graphs) to keep defenders decisively ahead
