Responsibilities
Build features that make Sapien a daily driver for finance teams. Design experiences that pull users in every day because the platform is proactively surfacing insights, catching issues before they become problems, and making their work faster and smarter
Design interfaces that make complex agent operations understandable and controllable for finance teams who aren't technical
Implement human-in-the-loop systems where users can give feedback, correct agent mistakes, and teach the system about their specific business processes. Build the feedback loops that make agents smarter over time
Make product and technical decisions: what should this feature do, how should the UI work, what's the right database schema, which technologies should we use. You're not just implementing specs, you're figuring out what to build
Qualification
Required
Comfort with modern web technologies: React, TypeScript, Python, SQL, and common backend frameworks
Product mindset. You think about user experience, not just implementation

CS degree or equivalent experience. We care most about what you've built
