Portless招聘AI工程师（美国）

At Portless, we specialize in global delivery solutions for SMBs and enterprise merchants, enabling businesses to ship direct-from-factory from manufacturing hubs like China to destinations worldwide.

Strong programming skills in Python and/or TypeScript/JavaScript; comfortable building both backend services and lightweight frontend interfaces
Experience building RAG pipelines, embedding workflows, or agentic systems using frameworks like LangChain, LlamaIndex, or similar

Experience working cross-functionally with non-technical stakeholders to scope and deliver AI projects
Proven ability to evaluate AI output quality and build evals/testing frameworks for LLM-based systems
Logistics, supply chain, or B2B SaaS experience is a strong plus
