About the role
- We're looking for a hands-on Principal Engineer to lead the architecture and technical direction of Inflection's agentic AI systems.
- You'll build production AI agents that can reason, retrieve context, use tools, and safely execute complex workflows while driving the design of scalable agent architectures, evaluation frameworks, observability, and reliability systems.
- Partnering closely with product, design, and engineering, you'll turn ambiguous problems into AI-native experiences, mentor senior engineers, and help establish the technical standards that power the next generation of intelligent agents.
Responsibilities
- Build production AI agents that can plan, retrieve context, call tools, take actions, and recover from failures.
- Design agent architectures for task decomposition, tool routing, memory, state management, human approval, and safe execution.
- Create evals and observability systems for multi-step task success, tool-call accuracy, hallucination resistance, latency, cost, and failure modes.
- Partner with product, design, and engineering teams to turn ambiguous user problems into shipped AI-native features.
- Own the technical direction of agentic AI systems, provide support and coaching to the team.
- Experience building LLM-powered products, AI agents, RAG systems, automation workflows, or model-integrated applications.
- We are focused on building a positive, safe, inclusive and inspiring place to work.
- Support of country-specific visa needs for international employees living in the Bay Area
Requirements
- Strong Python or TypeScript experience.
- Experience with tool/function calling, structured outputs, embeddings, retrieval, prompt design, and model evaluation.
- Strong product judgment and ability to move from ambiguous problem to shipped product quickly.
- Ability to work effectively in a fast-moving environment with ownership, collaboration, and high technical standards.
- Have a bachelor's degree or equivalent in a related field to the offered position requirements
Nice to have
- Experience with LangGraph, LlamaIndex, OpenAI, Anthropic, Hugging Face, vLLM, or similar tools.
- Experience with agent memory, planning, multi-agent systems, browser automation, workflow automation, or AI copilots.
- Experience with enterprise SaaS, productivity tools, developer tools, CRM, support, sales, finance, legal, or operations workflows.
- Experience working in early-stage, high-growth, or zero-to-one product environments
