Senior Product Designer - Design Systems

In 1977 Christopher Alexander wrote “A Pattern Language” – a book about architecture and urban planning that proposed a framework of reusable solutions to common design problems. Importantly, this was a toolkit, not a blueprint – allowing for flexibility and creativity to cater to specific needs. This thoughtful approach ensures that the environments created are cohesive and functional, but also allows for them to be beautiful and personal.

In a similar sense, we at Mercury are creating a software environment that allows for the most efficient functionality while still being something that people can love and make their own. We’re a financial technology company that helps startups spend less time banking* and more time building. We believe that the key to our success revolves around thoughtful, scalable, and beautifully crafted design.

What We're Looking For

A product designer to lead and evolve Mercury’s Design System. In this role, you’ll own how our components, patterns and guidelines scale across products - driving consistency, accessibility, and a best-in-class experience for our customers. We’re looking for a seasoned systems architect who thrives at the intersection of design systems, product design and front-end development. You’ll collaborate closely with product designers, engineers and brand partners to create scalable, intuitive and elegant solutions that elevate the Mercury experience and set a high standard of craft across the company.

Our design team consists of 40+ people who love to solve complex problems through design, but are equally passionate about cultivating, guiding, and inspiring each other.

Key Responsibilities

Shape and evolve Mercury’s Design System, ensuring it is both beautiful and practical.

Translate high-craft design into scalable systems and pattern libraries that integrate smoothly into product work.

Work directly with our engineering and design teams to develop and implement tooling with a focus on maintaining speed & quality.

Represent and evangelize the Mercury Design System internally as its face and champion, building alignment, adoption and support across teams.

The ideal candidate for the role has:

Design systems expertise: comfortable and motivated to work on behind-the-scenes system design as much as product-facing work.

Excellent communication & presence: able to represent design systems internally, inspire confidence, and foster adoption.
