AI Engineer

About this role

NetBrain seeks a Senior AI Engineer to design and build production-grade agent and RAG systems for intelligent network automation. You'll own architecture, evaluation, scalability, and reliability—moving quickly from prototype to production while maintaining a focus on safety and real-world impact.

What you'll do

• Design and implement enterprise-grade agent platform architecture with orchestration patterns (ReAct, Plan-and-Execute, Supervisor) and safety guardrails
• Build agent execution and governance mechanisms including human-in-the-loop workflows, multi-tenant isolation, and policy enforcement
• Develop LLM post-training strategies using SFT, DPO/RLHF, and parameter-efficient techniques (LoRA) for domain-specific optimization
• Create reusable agent skills, standardized tool interfaces, and a scalable tool ecosystem integrated with NetBrain platform
• Implement self-learning feedback loops converting production traces and user feedback into training data
• Ensure production reliability, observability, scalability, and quality across all AI systems

What they're looking for

• Agent system design and orchestration patterns
• Large language models and prompt engineering
• Fine-tuning techniques (SFT, DPO, RLHF, LoRA)
• RAG (Retrieval-Augmented Generation) systems
• Python and production engineering practices
• System architecture and scalability design
• Network operations domain knowledge (preferred)
• Evaluation frameworks and metrics for AI systems
