Front-End Developer (Remote SA) - Get AI-powered advice on this job and more exclusive features. Role Overview We’re looking for a Frontend / Fullstack Engineer who can deeply understand and reconstruct complex product experiences — from UI structure and navigation patterns to workflow logic and behavioral nuances. In this role, you’ll replicate production-grade SaaS platforms using synthetic data and functional user flows. These replicas help our agent systems train, evaluate, and improve on real-world software interactions. You’ll collaborate within a small, high-performing team (3 engineers) to rapidly build interfaces that feel indistinguishable from live products. This is a high-impact, high-ownership role with fast iteration cycles and direct influence on what our agents can learn to do. What You’ll Do Recreate complex SaaS workflows (e.g., expenses, reimbursements, employee/card management in financial platforms like Ramp) with high fidelity to real product behavior. Build functional replicas of web platforms using dummy or synthetic data to capture authentic logic and flow. Design and structure TSX/React component hierarchies with clean state and data management. Make smart trade-offs around scope, UI parity, and workflow accuracy to deliver quickly and effectively. Review contributions from other engineers to ensure clarity, consistency, and engineering excellence. Example Project You might be tasked with replicating a financial SaaS platform like Ramp , focusing on: Expense and reimbursement workflows Virtual card issuance and management Organization and billing views Lightweight accounting and reporting pages Navigation and UX patterns mirroring the reference product Reference: — no backend or login required; goal is functional demonstration only. What We’re Looking For Proven experience working with React and TypeScript in production environments. Strong understanding of frontend architecture, state management, and component composition. Excellent product sense — you care about correctness, polish, and UX fidelity. Ability to reverse-engineer and accurately reproduce product workflows from observation. Self-directed and accountable — able to own a project from start to finish with minimal oversight. Exceptional written and technical communication, especially around reasoning, debugging, and tradeoffs.
