Mercury is a financial technology company that provides online business banking services, although it is not a bank itself. It partners with FDIC-insured banks like Choice Financial Group, Column N. A. , and Evolve Bank & Trust to offer banking services. Mercury aims to simplify financial operations for startups and businesses by offering a range of services including checking and savings accounts, treasury management, corporate cards, expense management, invoicing, and accounting automations. The platform is designed to streamline various banking tasks and enhance financial workflows with features like fraud monitoring and account security. It also offers investment opportunities through its Mercury Treasury product and startup support through its Mercury Raise platform.

📋 Description

• Build and maintain the components, patterns, and foundations (tokens, type, color, layout) that Mercury's product is woven from, holding a high bar for accessibility, performance, and pixel-level craft. • Lead projects that ship new UI patterns to solve real pain points for product teams, helping them build better experiences faster. • Develop a design system that's as ready for AI as it is for people, applying the technology to create leveraged outcomes. • Invest in the design system's prototyping experience, shaping the next iteration of how our design function rapidly prototypes, iterates on the product, and explores new concepts. • Raise the craft and AI fluency of the people around you, through mentorship and clear best practices.

🎯 Requirements

• 4+ years of frontend development, with deep experience in React, TypeScript, and modern web technologies. • Experience building or maintaining a design system or shared component library. • A thorough command of modern frontend tooling: build systems, CI/CD, and testing. • High agency, and comfort creating clarity in ambiguous spaces. You take ownership and move without waiting for a defined path. • First-principles systems thinking that stays oriented to outcomes. You make clear decisions that drive toward results instead of getting stuck in open questions. • Strong product taste, and an instinct for leverage: the change that makes many teams better, not the one component polished in isolation. • Hands-on fluency at the intersection of AI and software development: a real command of how emerging AI paradigms are changing the way software gets built, and the ability to turn that into practical leverage, both for the design system itself and for the people who build on it.
