ServiceNow is hiring a Staff AI Engineer: Foundational AI Services to architect and scale the core AI intelligence layer. This role builds the foundational AI services that empower every product team to deploy production-grade GenAI. You will own the end-to-end lifecycle of internal AI infrastructure, creating high-performance, resilient, and autonomous systems.
What You'll Do
- Lead domain-specific model optimization using PEFT (LoRA/QLoRA) and knowledge distillation to balance cost, latency, and reasoning capability.
- Build next-gen Retrieval-Augmented Generation pipelines using hybrid search, cross-encoders, and self-correcting retrieval loops.
- Design and deploy multi-agent systems using frameworks like LangGraph or CrewAI, enabling autonomous task planning and tool-use (Function Calling).
- Build 'LLM-as-a-judge' frameworks and robust evaluation pipelines to measure hallucination rates, groundedness, and safety.
- Implement high-throughput, low-latency serving strategies including quantization, speculative decoding, and prompt caching.
What We're Looking For
- Typically requires 8+ years of overall software engineering experience.
- Expert-level mastery of Transformers, attention mechanisms, and the latest frontier models (GPT-4o, Claude 3.5, Llama 3).
- Deep experience with vector databases (Pinecone, Weaviate, Milvus), orchestration layers (LangChain, LlamaIndex), and MLOps tools.
- Staff-level coder in Python/Rust who understands distributed systems, concurrency, and API design.
- Proficiency with Chain-of-Thought (CoT), DSPy, GraphRAG, and Semantic Caching.
Technical Stack
- Languages: Python, Rust
- Core AI: Transformers, GPT-4o, Claude 3.5, Llama 3
- Vector Databases: Pinecone, Weaviate, Milvus
- Orchestration & Frameworks: LangChain, LlamaIndex, PEFT (LoRA/QLoRA), LangGraph, CrewAI, DSPy, GraphRAG
