Role summary
We’re building a new AI capability that will be embedded across Payoneer’s products and internal operations.
Our mission is to create reusable, production-grade Multi AI agents System that can understand context, connect to Payoneer’s data and business logic through secure tools/APIs.
This is not a single feature or a one-off chatbot. It’s a long-term engineering effort to design and deliver a scalable multi-agent system that can support many use cases across channels.
You’ll work on agents, tooling, orchestration, observability, evaluation, and safe deployment patterns.
What you’ll do
- Build backend services in Node.js (TypeScript) to run and serve agents across multiple products and channels.
- Implement agent workflows: routing, orchestration, tool calling, and synthesizing results into UI/API-ready outputs.
- Build and maintain high-quality Tools agents consume: secure internal API connectors, data fetchers, business logic wrappers, and knowledge retrieval.
- Add observability: tracing, logging, prompt/model versioning, token/cost tracking, and quality metrics.
- Create evaluation harnesses: regression checks, and feedback loops to continuously improve accuracy and reliability.
- Collaborate with Product/Operations/Security
Who you are
- 3 years of hands-on Node.js + TypeScript experience
- BS Degree in computer science
- Experience building backend services (preferably NestJS)
- Strong fundamentals: REST APIs, async patterns, debugging, performance considerations
- Experience working with data sources (SQL and NoSQL)
- Experience with distributed systems: caching (Redis), queues (Kafka/RabbitMQ), containers/K8s
- Strong knowledge in CI/CD + feature flags + environment separation (dev/test/prod)
- Strong learning ability - fast to pick up new domains, tools, and patterns, and comfortable working in ambiguity
- High ownership and strong work ethic - motivated, proactive, and willing to work hard to deliver high-impact outcomes
- Team player with clear communication skills and a practical, solution-oriented mindset
- LLM/agent experience (OpenAI/Azure OpenAI, LangChain/LangGraph, function/tool calling) - Nice to have
- Observability tools (Langfuse, OpenTelemetry, Grafana/Datadog, etc.) - Nice to have
Why join this team
- Build a foundational AI capability that will power multiple high-impact use cases across the company
- Work on real production constraints: reliability, security, cost control, and measurable outcomes
- High ownership and strong technical depth with fast iteration and visible business impact
