About the role About Us Lumari streamlines operations for supply chain teams with AI agents that monitor, coordinate, and take action. Supply chain is how the modern world actually works. Every physical product you use, from cars and phones to chairs and machines, depends on a vast coordination network to source materials, manage production, and deliver on time. When supply chain breaks, everything stops. A single delayed component can halt an entire factory. A missed delivery can kill a product launch. We enable these teams to stay ahead of these issues before they turn into major operational crises. If you want to build a product that drives real-world impact at enterprise scale, join us. You'll ship fast, work directly with customers, and help make agents reliable in real operations. What You’ll Do Build AI agents from the ground up: designing orchestration logic, tool calling, prompting, and decision-making flows that work reliably in production environments Ship full-stack features end-to-end, from backend services and data models to frontend interfaces Design clean, intuitive UI/UX for complex workflows Own features from idea to production: build, launch, monitor, and improve Iterate quickly based on customer feedback, and turn ambiguous problems into shipped product Work closely with co-founders (ex-Google, ex-Stripe) to set engineering and product direction What We’re Looking For Strong full-stack experience shipping production software with React, TypeScript, Python, FastAPI, Next.js Experience building with AI and LLMs: tool calling, prompting, structured outputs, guardrails, and agent workflow design Solid system architecture thinking: you can design scalable, maintainable systems and make smart tradeoff decisions Power user of AI coding tools (Cursor, Claude Code, etc.) and ability to use them to move faster without sacrificing quality Design sense and attention to detail: you care about how interfaces look and feel, not just how they work Proactive ownership mindset: you fix problems as you see them and can independently turn requirements into production-ready code Bonus Points (optional) Prior startup experience, founding engineer role, or you've been a founder yourself Experience working in or alongside supply chain, logistics, procurement, or operations teams Built or worked with traditional ERP software (SAP, NetSuite, etc.) or supply chain management systems About Lumari Lumari is the world's first AI-powered procurement automation platform purpose-built for direct materials and supply chain execution.
