How to Apply for Senior Backend Engineer - AI Product

at Re:Build Manufacturing

🏢 About Re:Build Manufacturing

Re:Build Manufacturing is revitalizing U.S. manufacturing by integrating cutting-edge technology into traditional manufacturing processes. What makes them unique is their focus on building AI-native platforms specifically for hardware development teams, bridging the gap between software and physical product creation. Someone would want to work here to be at the intersection of AI innovation and tangible manufacturing impact.

About This Role

This Senior Backend Engineer role involves building core services and AI infrastructure for Reflow, an AI-powered platform for hardware product development. You'll be creating everything from REST APIs to AI agent infrastructure that listens across existing tools and coordinates changes proactively. This is impactful because you'll be solving real-world problems in hardware development where missed communication causes significant damage.

💡 A Day in the Life

A typical day involves collaborating with AI researchers and the product head to design services that turn unstructured hardware development data into actionable insights. You'll be building and optimizing FastAPI endpoints, PostgreSQL data models, and AI agent infrastructure that proactively coordinates changes across hardware development tools and teams.
