The role
This company builds AI agents that automate complex, data-intensive workflows for financial services. These digital teammates reason across vast datasets, write code, and produce client-ready outputs — often 20x faster than human consultants. They've achieved significant traction in under a year, securing one of the largest Series A rounds in fintech history from leading investors.
You'll join as a Lead Front-End Engineer, owning the front-end craft across the entire product. This isn't about building features in isolation. It's about defining the architectural patterns, guidelines, and quality standards that every engineer — and even the AI agents themselves — will build against. You'll shape how a full-stack team scales its UI output, ensuring consistency and performance as the company grows rapidly.
