Mercury is a fintech platform providing banking, treasury, and financial workflow solutions for startups and technology companies. The Design Systems team is hiring a Frontend Engineer to evolve shared components and patterns that help product teams build consistent, accessible, and well-crafted interfaces.
You will work closely with designers and engineers to understand product needs, explore solutions, and deliver improvements to teams across Mercury. This role is explicitly open to early-career and intermediate engineers, with meaningful project ownership and guidance from experienced teammates matched to your experience level.
Key responsibilities include:
- Building shared React and TypeScript components and patterns that solve recurring product needs and serve as flexible solutions across different experiences
- Partnering with designers and product engineers to connect design intent with working software, evolving components and tokens across Figma and code based on real product feedback
- Improving the quality and accessibility of experiences built with shared components, including thoughtful interactions, reliable behavior, and inclusive design
- Making the design system easier to adopt by improving documentation, examples, and workflows that help teams build confidently
- Using AI coding tools to explore approaches and move ideas into working code, applying judgment to generated output and testing in context
As opportunities and interests align, you may also contribute to code-based prototyping and tools that help designers and AI agents work with Mercury's components.
Requirements:
- Foundation in React, TypeScript, HTML, and CSS with experience building interfaces and ability to explain your code decisions
- Care for visual craft and user experience, including interest in accessible interfaces and interaction details
- Hands-on fluency with AI coding tools; ability to provide context, evaluate and improve generated code, and verify functionality
- Ownership mindset with willingness to learn; you follow work through, communicate when you need help, and use feedback to improve
- Curiosity about reusable systems and the tradeoffs involved in serving different product needs with shared components
- Interest in solving problems alongside designers and engineers, contributing ideas, and understanding needs behind requests
- Plus: experience with design systems, prototyping, or developer tooling (not required)
Your experience may come from professional work, internships, coursework, open source, or personal projects.
