It all started in sunny San Diego, California in 2004 when a visionary engineer, Fred Luddy, saw the potential to transform how we work. Fast forward to today — ServiceNow stands as a global market leader, bringing innovative AI-enhanced technology to over 8,100 customers, including 85% of the Fortune 500®. Our intelligent cloud-based platform seamlessly connects people, systems, and processes to empower organizations to find smarter, faster, and better ways to work. But this is just the beginning of our journey. Join us as we pursue our purpose to make the world work better for everyone.

Staff AI Engineer: Foundational AI Services

We are looking for a visionary Staff AI Engineer to architect and scale our core AI intelligence layer. In this role, you won't just be building features; you will be building the "AI Operating System" for our company—the foundational services that empower every product team to deploy production-grade GenAI.

The Mission

As a Staff Engineer, you will own the end-to-end lifecycle of our internal AI infrastructure, moving beyond simple wrappers to create high-performance, resilient, and autonomous systems.

Key Responsibilities

• LLM Fine-Tuning & Distillation: Lead domain-specific model optimization using PEFT (LoRA/QLoRA) and knowledge distillation to balance cost, latency, and reasoning capability.
• Architect Foundational RAG: Build next-gen Retrieval-Augmented Generation pipelines using hybrid search, cross-encoders, and self-correcting retrieval loops.
• Agentic Orchestration: Design and deploy multi-agent systems using frameworks like LangGraph or CrewAI, enabling autonomous task planning and tool-use (Function Calling).
• Enterprise-Grade Evaluation: Build "LLM-as-a-judge" frameworks and robust eval pipelines to measure hallucination rates, groundedness, and safety.
• Inference Optimization: Implement high-throughput, low-latency serving strategies including quantization, speculative decoding, and prompt caching.

Why Join Us?

You will be the technical lead for a mission-critical team, setting the standard for how AI is built and scaled. This is a high-impact role where your architecture will directly influence the intelligence of our entire ecosystem.

To be successful in this role you have:

• Typically requires 8+ years of overall software engineering experience.
• Core AI: Expert-level mastery of Transformers, attention mechanisms, and the latest frontier models (GPT-4o, Claude 3.5, Llama 3).
• The Stack: Deep experience with vector databases (Pinecone, Weaviate, Milvus), orchestration layers (LangChain, LlamaIndex), and MLOps tools.
• Software Craft: You are a Staff-level coder in Python/Rust who understands distributed systems, concurrency, and API design.
• Modern Buzz: You live and breathe Chain-of-Thought (CoT), DSPy, GraphRAG, and Semantic Caching.
