Our mission is rooted in people inspired innovation, empowering financial institutions to deliver seamless, secure, and human centered experiences. We deliver cutting-edge solutions that are paving the way for the next generation of digital banking and payments, but our true impact begins with our associates.  If you're ready to help transform an industry and grow with a company that values purpose, collaboration, and excellence then we’d love to meet you. 
At the heart of every great user experience is a seamless, invisible foundation. We aren’t just building buttons and inputs; we are crafting the digital DNA that powers our entire product ecosystem. As a Software Engineer - Design System, you’ll be the bridge between visionary design and scalable code. You will have the unique opportunity to empower hundreds of developers with a robust, high-performance UI library built on the standards of the future. If you are passionate about browser-native technologies, pixel-perfect execution, and building tools that make other designers’ and engineers' lives easier, you’ve found your home.
As a Software Engineer - Design System, you will evolve Forge, Jack Henry’s design system, and function as the crucial link between designers and engineers, helping standardize and optimize how we build software at scale. We are looking for a specialist who lives and breathes design engineering.

What you’ll be responsible for:
Component development: Develop, test, and document web components, ensuring they adhere to accessibility standards and are optimized for performance across different browsers and devices.
Token Management: Maintain and scale our design token system to ensure brand consistency across platforms.
System Architecture: Contribute to the underlying system architecture to ensure codebase evolution and adoption of modern technologies at scale.
Accessibility First: Implement WCAG 2.2 standards across the system to ensure our products are inclusive by default.
Designer/Developer Experience (DX): Design predictable and robust APIs, write clear documentation, create component playground environments, and provide support to product teams adopting the system.
Develop Tooling: Maintain monorepo tooling and CI/CD pipelines, develop custom workflows and figma plugins, and maintain our tool chain.
Innovation: Drive continuous improvements by keeping up to date with industry trends and emerging technologies, and by exploring AI applications to further innovate both the design system and developer tooling.
Travel Requirement: Some travel required for onsite projects and team meetups.
May perform other job duties as assigned.

What you’ll need to have:
Minimum of 4 years of experience in software engineering.
Experience in frontend engineering with a focus on design systems developed in Web Components, React, or Vue.
High proficiency in modern JavaScript and Node.js, with a deep understanding of JavaScript runtimes (browsers and servers), web accessibility, and DOM architecture.
Deep understanding of CSS (e.g., Custom Properties, Flexbox/Grid, Container Queries, etc.) and design token architectures.
Understanding of web architecture and some experience with product development to better understand your customers.
Strong attention to detail and able to create pixel accurate code from Figma design specs, execute integration tests, visual tests, and unit tests to produce consistent and bug free assets.
A curious mind and willingness to dig deep into the latest specifications and remain up to date with new technologies to evolve the design system.

What would be nice for you to have:
Bachelor’s degree in software engineering, human computer interaction, computer science, or related field, preferred, but not required.
Hands-on experience with native web components and Lit.
Hands-on experience designing components in Figma.
Open source software contribution experience.
