Staff AI Engineer, Payments Intelligence

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.

What This Unit Owns

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

How AI Shows Up in This Role

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

Your Contribution Will Be

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

What Success Looks Like

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.

Skills You Need

Minimum 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

Preferred Qualifications

Fine-tuning, RLHF, or model customization

Vector databases (Pinecone, Weaviate, or FAISS) and embedding retrieval
