Front-End Developer

We are looking for a Front-End Developer to join our Design System team. You will build and maintain a library of reusable web components that power operator-facing displays on heavy machinery. Working alongside a senior team lead and our UX design partners, you will turn design specifications into accessible, well-tested, and well-documented components used across multiple product teams.

This is a hands-on role for a developer who enjoys craftsmanship: clean component APIs, pixel-faithful implementation, thoughtful documentation, and a strong testing culture.

Advantages
Real-World Impact: Work on software that heavy machinery operators rely on every day in the field.

Mature Engineering Environment: Build on a mature, well-structured component library with clear conventions and strong mentorship from a senior lead.

Design Leadership: Shape the visual and interaction language used across an entire product family.

Responsibilities
• Build and maintain reusable web components using Lit and TypeScript
• Translate Figma designs into production-ready components, including gauges, indicators, controls, and data visualizations
• Implement styling with CSS custom properties and design tokens, ensuring consistency across the library
• Write interactive Storybook stories and documentation for every component you ship
• Write unit, integration, and visual regression tests in a browser-based testing environment
• Participate in code reviews and follow established conventions for naming, versioning, and changelogs
• Collaborate with UX designers to keep design and code in sync
• Support consuming teams by answering questions, triaging issues, and improving component ergonomics

Qualifications
Required Qualifications
2 to 5 years of professional front-end development experience
Strong proficiency in TypeScript and modern JavaScript (ES modules, asynchronous patterns)
Hands-on experience with native Web Components (Custom Elements, Shadow DOM, slots); experience with Lit is strongly preferred
Solid grasp of core CSS fundamentals: custom properties, Flexbox/Grid, relative units, transitions, and animations
Practical knowledge of web accessibility (ARIA, keyboard navigation, focus management)
Experience writing automated front-end tests (unit or browser-based) Proficiency with Git workflows based on pull requests and code reviews
Strong attention to detail and a commitment to documenting your work

Desired Qualifications

Experience contributing to or maintaining a design system or component library Familiarity with Storybook (stories, controls, MDX documentation)
Experience inspecting Figma mockups; familiarity with Figma Code Connect or design tokens is an asset
Experience with SVG, Canvas, or CSS animations and data visualizations Basic knowledge of Three.js or WebGL
