Job summary

Yuno is seeking a Staff AI Engineer to lead Payments Intelligence, building AI agents and intelligence products that make payments smarter across the platform. You will architect production AI-agent systems, shape LLM deployment, and raise the technical bar for engineers while guiding cross‑functional teams.

In this hands‑on leadership role, you’ll design multi‑step agents with tooling, memory, and retrieval augmented generation, ensure safety and compliance, and mentor engineers across Product,

Qualifications

• 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 — plus solid automated testing and CI/CD.
• Proven technical leadership — mentoring engineers, driving technical vision, and delivering complex, cross‑team projects.
• English — advanced proficiency, written and spoken.

Responsibilities

• Agent architecture and technical leadership — own the architecture of Yuno's AI agents (AIDA, NOVA) and intelligence systems; set the technical direction for agentic AI and raise the bar for the team.
• Production LLM and agentic systems — design multi‑step agents with tool use, orchestration, memory, and retrieval‑augmented generation (RAG), engineered for reliability and low latency at scale.
• Conversational and multilingual experiences — build agents that hold real, dynamic customer conversations across channels (phone, WhatsApp) and 70+ languages, adapting to context and intent.
• Evaluation, safety, and guardrails — define how the unit measures agent quality and safety, with rigorous evaluation, observability, and guardrails so agents behave reliably in a compliance‑sensitive, multi‑market environment.
• Intelligence and data products — architect the client‑intelligence systems that turn payment data into actionable insight for merchants.
• AI Ops automation — build the AI‑driven automation that streamlines internal operations and support.
• Mentorship and cross‑functional collaboration — mentor engineers and partner with Product, Data Science, and Staff Engineers across domains to ship complex, cross‑team AI work.
