What We Need

We’re looking for a Senior AI Engineer to design and build production-grade agent and RAG systems that power intelligent, reliable automation across our platform. This role combines hands-on engineering with system-level thinking—owning everything from architecture and evaluation to scalability, observability, and reliability in production. The ideal candidate thrives in ambiguity, moves quickly from prototype to production, and brings a strong focus on quality, safety, and real-world impact.

What You'll Do

Agent Platform Architecture

• Design and implement core capabilities for an enterprise-grade Agent platform, including orchestration patterns such as ReAct, Plan-and-
• Execute, and Supervisor, as well as tool execution, context and memory management, and safety guardrails.
• Design enterprise-grade Agent execution and governance mechanisms, including Human-in-the-Loop approval workflows, multi-tenant
• permission isolation, policy enforcement, and secure execution controls.
• Build reusable Agent Skills, standardized tool interfaces, and a scalable tool ecosystem deeply integrated with NetBrain platform
• capabilities and business workflows.

LLM and Model Optimization

• Design and implement LLM post-training strategies, including domain-specific Supervised Fine-Tuning (SFT), DPO/RLHF-based
• preference alignment, and parameter-efficient fine-tuning techniques such as LoRA, to continuously improve model performance in the
• network operations domain.
• Build an Agent self-learning feedback loop that converts production execution traces, user feedback, and evaluation results into high-
• quality datasets for continuously improving prompts, skills, models, and retrieval strategies.
• Analyze and optimize LLM behavior across areas such as instruction following, tool calling, structured output generation, contextual
• understanding, reasoning stability, and hallucination mitigation.

Evaluation, Reliability, and Observability

• Build production-grade LLM and Agent evaluation frameworks and automated regression pipelines, including benchmark datasets,
• deterministic checks, LLM-as-a-Judge, tool-call validation, retrieval-quality evaluation, and end-to-end task success metrics.
• Establish release quality gates and hallucination-detection mechanisms for AI features to prevent significant accuracy, reliability, and
• performance regressions from reaching production.
• Build comprehensive AI system observability capabilities, including distributed tracing, structured loggin

ng, including LoRA or other parameter-efficient fine-tuning techniques.

• Experience applying LLM technologies to networking, infrastructure, cybersecurity, observability, or other complex technical domains.
• Fluent in both English and Chinese, with strong cross-regional communication and collaboration skills.
