About the Role

Mercury's Design Systems team focuses on building consistent, accessible, and well-considered interfaces. We are seeking a Frontend Engineer to help evolve shared components and patterns, enabling teams across Mercury to create high-quality software. You will collaborate closely with designers and engineers to understand product needs, explore solutions, and implement improvements. This role is suitable for early-career and intermediate engineers, offering opportunities to develop frontend engineering and design systems expertise through project ownership and guidance from experienced teammates. Your primary focus will be on design systems, within the team's broader Design Foundations work. As opportunities arise, you can also contribute to code-based prototyping and tools for designers and AI agents. Strong AI fluency is a key aspect of our development process.

Key Responsibilities

• Build shared React and TypeScript components and patterns that enhance Mercury's interfaces, addressing recurring product needs with flexible solutions.
• Partner with designers and product engineers to translate design intent into functional software, evolving components and tokens across Figma and code, and incorporating feedback from product work.
• Improve the quality of experiences built with our components by considering user accessibility, thoughtful interactions, and reliable behavior during implementation and testing.
• Enhance the usability of the design system by assisting teams with the adoption of shared patterns and improving documentation, examples, and workflows.
• Utilize AI tools to explore development approaches and translate ideas into code, evaluating and refining AI-generated code in context.

Requirements & Tech Stack

• Foundation in React, TypeScript, HTML, and CSS, with experience in building interfaces and the ability to articulate design decisions.
• Demonstrated care for visual design and user experience, including an interest in accessible interfaces and interaction details.
• Hands-on fluency with AI coding tools, including providing context, evaluating, and verifying generated code.
• Ownership, willingness to learn, clear communication, and receptiveness to feedback.
• Curiosity about reusable systems and the challenges of serving diverse product needs with shared components.
• Interest in problem-solving collaboratively with designers and engineers, contributing ideas, and understanding underlying requirements.
• Experience with design systems, prototyping, or developer tooling is a plus.

Qualifications

• Experience may stem from professional work, internships, coursework, open source, or personal projects.
• You do not need prior experience in a design systems role to contribute valuable skills and ideas.
