Acquia. Built for every audience, human or otherwise. The Role: Acquia is seeking a Staff AI Engineer to join our AI Core Engineering team. This is first and foremost a hands-on engineering role — you will spend the majority of your time designing, building, and shipping production-grade agentic AI workflows across the Acquia DXP. LangGraph, Temporal, Pydantic and LangFuse are your primary tools; enterprise reliability, observability, and scale are your standards. You'll also play a light but meaningful mentoring role, helping to lift the AI engineering capability of those around you as the team grows. Key Responsibilities • Write and ship production AI code daily — you are an active contributor. • Architect agentic AI workflows using LangGraph, Temporal, Pydantic — stateful, multi-agent workflows built for enterprise scale and reliability. • Own AI observability via LangFuse: tracing, prompt versioning, evaluation, and performance benchmarking across all model interactions. • Set AI engineering standards for agent design patterns, RAG, prompt management, context optimization, and tool-calling strategies. • Partner with product and platform teams to deliver AI architectures that meet enterprise SLA, security, and compliance requirements. • Evaluate and adopt emerging tooling — benchmarking LLM providers, orchestration frameworks, and agentic stack improvements. • Mentor engineers as a natural extension of your work — sharing knowledge through code reviews, pairing sessions, and design discussions, not through management overhead. • Represent Acquia's AI capabilities in customer architectural reviews, technical discovery, and roadmap conversations. Required Experience • 8+ years of software engineering with 3+ years in production of AI Agents. • Hands-on LangGraph, Temporal, Pydantic expertise — stateful, cyclic, multi-agent workflows at enterprise scale. • Hands-on LangFuse expertise - tracing, evaluation, prompt management, and dataset- driven testing • Proficiency with agent harness frameworks such as LangChain or similar (e.g. LlamaIndex, CrewAI) — composing chains, tools, memory, and retrieval pipelines. • Deep Python proficiency and strong engineering fundamentals (testing, CI/CD, architecture). • Cloud AI deployment experience (AWS, Azure, or GCP) including containerization and inference cost management. • RAG architecture knowledge— vector databases, embedding models, and retrieval strategies. • B.S. in Computer Science or equivalent practical experience. Desired Skills • Enterprise SaaS or CMS, including familiarity with Acquia's Drupal-based DXP experience • Agentic development workflow fluency — AI-assisted coding tools (Copilot, Cursor, Claude) as everyday accelerators. • Familiarity with persistent agent runtimes - such as OpenClaw and Hermes Agent, understanding cross-session memory, autonomous skill creation, and always-on agent infrastructure as it matures in enterprise contexts. • LLM fine-tuning or model evaluation experience and awareness of foundational model tradeoffs. • Human-in-the-loop — interrupt-driven agents and ente
