What You'll Do • Design and build purpose-specific AI coding agents for supply chain connectivity. • Develop and maintain infrastructure for hosting and running integrations. • Own core systems end to end, from the agent platform to the integrations runtime. • Make foundational architectural decisions and establish engineering practices as the team grows. What We're Looking For • Two to five years of experience as a full-stack or backend engineer, with experience owning complex products end to end. • Proficiency in TypeScript and modern full-stack development; experience with React, Bun, Effect-TS, PostgreSQL, Kubernetes, or AWS is relevant. • Hands-on experience building with AI agents or large language models using current approaches. • Experience building backend or infrastructure systems such as runtimes, orchestration, or cloud platforms, in addition to product interfaces. • Early-stage startup experience, including building products or systems from scratch and working with a high degree of autonomy. • Strong engineering fundamentals and the ability to work across both product development and infrastructure.
