Full-Stack Engineer

About the role

You'll build features end-to-end for Sapien's core platform. This means taking a feature from design through frontend implementation, backend APIs, database changes, and agent integration. You own the full experience and make it work. This is a role where you'll balance shipping new capabilities with keeping the platform stable and performant.

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.

Requirements

We're looking for someone who:

• Comfort with modern web technologies: React, TypeScript, Python, SQL, and common backend frameworks.
• Has a product mindset. You think about user experience, not just implementation. You've iterated on features based on how people actually use them.
• Can work with ambiguity. You can take a rough problem statement, talk to the right people, and figure out what actually needs to be built.
• Has a CS degree or equivalent experience. We care most about what you've built.
