Yuno is the AI-native operating system of global commerce, powering the financial infrastructure of enterprise merchants, banks, and wallets. Through a single API, Yuno connects them to pay-ins, payouts, fraud prevention, KYC/KYB, and stablecoins globally, so they can operate everywhere. Agnostic by design and connected to 1,000+ payment methods and 460+ integrations in 190+ countries, Yuno optimizes acceptance rates, reduces costs, and strengthens security through specialized AI agents that learn from every transaction. Global brands including McDonald's, NetEase Games, GoFundMe, and Rappi run their payments on Yuno.
Yuno is looking for a Staff AI Engineer to be the senior technical leader for Payments Intelligence — the unit building the AI agents and intelligence products that make payments smarter across the platform. You'll architect and build production AI-agent systems like AIDA and NOVA, shape how Yuno applies LLMs and agentic AI to real payment problems, and raise the technical bar for the engineers around you.
This is a hands-on AI leadership role at the frontier. You'll design agents that hold real conversations with customers, recover revenue, automate operations, and surface intelligence to merchants — all in a production, multi-market, compliance-sensitive environment. Your impact comes as much from setting the technical direction for agentic AI as from the systems you build.
Yuno Agents (AIDA & NOVA) — AIDA, the agent that retrieves payment data and answers technical questions for support and operations teams; and NOVA, the agents that recover revenue by turning failed payments into intelligent, multilingual customer conversations across channels
AI Ops & Support — AI-driven automation that streamlines internal operations and customer support
Client Intelligence — the AI and data products that surface insight and intelligence to Yuno's merchants
You're not adding AI to a product — you're building the AI that is the product: the agents, LLM pipelines, and intelligence systems at the core of Payments Intelligence
AI is our default execution layer: you're expected to use AI-assisted tooling fluently in your own work, and to define how the unit designs, evaluates, and ships agentic systems responsibly
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
Within your first 6–12 months, you've led the architecture of at least one core agent or intelligence capability, shipped agentic systems to production with real evaluation and guardrails behind them, and become the technical voice Yuno trusts on how to build AI agents responsibly at scale.
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
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
Running multi-tenant AI platforms or GPU/resource management at scale
Data pipelines and orchestration (Airflow, Prefect) and warehouses like Databricks, Snowflake, or BigQuery
Spanish proficiency
Languages — Python (AI/ML), Go and Kotlin (platform services)
AI & LLMs — LLM APIs and open models, agent frameworks, MCP, RAG
AI evaluation & observability — LangFuse, LangSmith, Braintrust, MLflow
Data & retrieval — vector databases, feature stores
Messaging — Apache Kafka, SQS
Databases — PostgreSQL, Redis
Infrastructure — AWS, Kubernetes, Docker, Terraform
Observability — Datadog, OpenTelemetry
CI/CD — GitHub Actions, ArgoCD
Version Control — Git / GitHub
