Stord is revolutionizing the logistics industry with our cloud-based supply chain platform. Our AI team builds intelligent, LLM-driven features — including conversational agents, automated workflows, and AI-powered decision support — that are deeply integrated across Stord 's product suite.

We are seeking a Senior Software Engineer to build core features on the AI Platform team. This is a hands-on engineering role — you will design and deliver complex AI-powered features, contribute to architectural decisions, and help raise the quality bar through strong technical execution. You'll work daily in our TypeScript-based AI platform built on Cloudflare Workers, building the agent infrastructure, tool systems, and integrations that power Stord 's AI capabilities.

The right person for this role ships reliable, well-designed systems and is growing toward technical leadership. You write clean, idiomatic TypeScript, you have experience building LLM-powered features in production, and you know the difference between accepting model output and directing it toward high-quality results. What You'll Do
Hands-On Engineering

Build and iterate on agentic AI features — tool calling, context management, multi-step workflows, and confidence-based routing

-
Implement prompt engineering patterns, evaluation frameworks, and observability for LLM-powered systems

-
Integrate ML model outputs via API layers, collaborating with Data Scientists to understand model requirements and design clean integration boundaries
