## Description

Principal Software Engineer to be the first engineering hire on this project and technical founder of this new division. You won't be implementing someone else's spec, you'll co design the product and architecture directly with the founders, write production code from day one, and lay the foundation for everything that follows. This is a true zero-to-one role: architect, coder, system designer, and future team builder rolled into one. What You'll Do - Partner with founders to translate a bold product vision into a world class technical architecture and initial codebase. - Design and build complex, high throughput distributed systems optimised for hybrid, air gapped, and on prem deployments. - Own the core workflow automation/orchestration engine, including deep understanding of its inner workings, customisation, and extensibility. - Build AI ready data pipelines and architecture so we can integrate advanced capabilities without rewriting core systems later. - Establish production
