Product Engineer

Who we are Sapien is rethinking how finance teams operate in the age of AI. We’re building toward an autonomous CFO —systems that run company financials end-to-end. Our platform analyzes complex financial data in real time to increase decision cadence, prevent costly mistakes, and surface value. Sapien has caught multi-million-dollar errors, saved thousands of jobs, and returned significant dollars to customers’ bottom lines. We partner with traditional businesses—manufacturing, healthcare, restaurants, and large enterprises—to deeply understand and automate their financial workflows. We’re HQ’d by Madison Square Park in NYC and backed by General Catalyst, Neo , and top operators from Google, OpenAI, Microsoft, Ramp, and Stripe (over $9M raised). The role You'll design and build the interfaces that make AI agents usable for finance teams. This means creating new interaction patterns for how humans work with autonomous systems, building the design systems that scale across our platform, and obsessing over the details that make complex workflows feel simple. This is a design-focused frontend role where craft and user experience matter deeply. You'll own the visual and interaction design of features while implementing them in production. What you'll do Design and build interfaces that make agent operations transparent and controllable. Create new interaction patterns for real-time AI workflows, verification systems, and human-in-the-loop feedback that don’t exist yet. Prototype and iterate rapidly on new interface concepts. Work directly with customers to test designs, watch how they interact with features, and refine based on real usage. Design information hierarchies that surface the right data at the right time. Help users understand complex financial operations, agent reasoning, and data relationships without overwhelming them. Establish design standards and documentation that help the team ship consistent, high-quality interfaces as we scale. What we're looking for Product thinking about user experience. You\'ve designed features, tested them with users, and iterated based on how people actually use them. Experience building or contributing to design systems. You understand component architecture, tokens, consistency, and how design scales across a product. Ability to balance beauty with function. You care about aesthetics but know when to prioritize usability, performance, and shipping. Frontend development experience with React and TypeScript. You can implement your designs in production-quality code, not just hand off mockup CS degree or equivalent experience. We care most about what you\'ve built. How you work (values we care about) Ownership : You see designs through to production. You don\'t stop at mockups. You implement them, refine interactions based on how they feel in the browser, and fix polish issues until it\'s right. Opinionated : You have strong perspectives on what makes good design and aren\'t afraid to advocate for user experience. You push back on features that would make the product worse and propose better solutions. Mission-driven : You understand that interface decisions determine whether finance teams trust and adopt AI. You care about building products that transform how businesses run. Collaborative excellence : You elevate the team\'s design thinking. You give thoughtful feedback on interfaces, share design patterns and techniques, and raise the bar for polish across the product. #J-18808-Ljbffr Sapien
