Founding Full Stack Engineer (AI-Native)

Skiffra is building the intelligence layer for the physical world. We translate complex, real-world environments into clear, actionable data. While most AI companies focus on digital industries, we design AI-native orchestration systems for the sectors that extract, move, and build ecosystems around us. We turn messy, high-stakes operations into intelligent, adaptive workflows that improve decisions in real time. Our first proving ground is mining and natural resources, but the platform is modular by design—built to scale into any industry where decisions are expensive and consequences are real.
