Yuno is seeking a Staff AI Engineer to lead the development of AI agents and intelligence products for payments. The successful candidate will architect and build production AI-agent systems, shape the application of LLMs and agentic AI, and raise the technical bar for the engineers around them.

Responsibilities:

• Architect and build production AI-agent systems like AIDA and NOVA
• Design agents that hold real conversations with customers, recover revenue, automate operations, and surface intelligence to merchants
• Define how the unit measures agent quality and safety, with rigorous evaluation, observability, and guardrails
• Build the AI-driven automation that streamlines internal operations and support
• Mentor engineers and partner with Product, Data Science, and Staff Engineers across domains

Requirements:

• Extensive software engineering experience, with a track record building and shipping production LLM or AI-agent systems
• Deep expertise in agentic systems, multi-step agents, tool use, orchestration, memory, and retrieval-augmented generation (RAG)
• Strong LLM application skills, prompt engineering, evaluation, and guardrails for reliable, safe outputs
• Strong Python for AI/ML, plus solid backend engineering (Go and/or Kotlin) to productionize systems at scale
• Model serving and LLM inference, with the cloud infrastructure to run AI workloads in production (AWS or similar)
• Evaluation and observability for AI, hands-on with tools like LangFuse, LangSmith, Braintrust, or MLflow
• Proven technical leadership, mentoring engineers, driving technical vision, and delivering complex, cross-team projects

Nice to Have:

• Fine-tuning, RLHF, or model customization
• Vector databases (Pinecone, Weaviate, or FAISS) and embedding retrieval
• Building agent workflows with MCP servers or modern agent frameworks
• Conversational AI and speech (speech-to-text / text-to-speech) and multilingual systems
• Experience in the payments or fintech industry
