We’re seeking a Founding Full Stack Engineer to help build the core of our AI-driven audit platform. You will work directly with the leadership team to design and implement the systems and interfaces that power our workflows. This role sits at the intersection of backend services, data models, and user-facing product, giving you the opportunity to ship features end-to-end—from database design to polished user experiences.

A major part of this role is turning complex, messy workflows into simple, reliable software that auditors can use without training. You will build APIs that integrate with AI agents, design review interfaces for AI outputs, and ensure the product feels fast, intuitive, and trustworthy.

This is an early, high-ownership role. You will shape core product architecture, influence how users interact with AI systems, and help define what modern internal audit software should look like. You should be excited about working closely with users, iterating quickly, and taking full responsibility for features from conception to production.
