UX Design Engineer (Ireland Remote)

Oomnitza is hiring a UX Design Engineer to own the design system, component library, and prototyping tooling that powers our Product Engineering team. In our model, Product Engineers run discovery and prototyping end-to-end; your job is to give them an opinionated, well-tested, well-documented platform so they can move fast without losing design quality.

This is a hands-on role. Most of your time is in code and design tooling: maintaining the system, evolving the Storybook component library, building scaffolding that makes prototyping fast, and consulting on the small number of interactions that are genuinely novel. The role can sit in the US or in Ireland since most of the work is with tooling and systems.

What You'll Do

• Own the Oomnitza design system end-to-end: visual language, interaction patterns, accessibility guardrails, and the rules that keep the product feeling like one product.
• Maintain and extend the Storybook component library. Components should be correct, documented, performant, accessible, and easy for Product Engineers to compose.
• Build and maintain the prototyping tooling (design tokens, AI-prompt scaffolds, design markdowns, starter kits) that lets Product Engineers move from idea to validated prototype in days.
• Consult with Product Engineers on UX interactions that fall outside the patterns, and produce the new pattern, component, or guidance that adds back to the system.
• Partner with engineering to keep the design system and the implementation library aligned. Identify when a one-off interaction should be promoted into the system.
• Hold the quality bar for design output across the team. Review prototypes against the system, flag drift, and make the right thing easy to do.
• Track the design-engineering space (Figma plugins, AI design tooling, headless component libraries, accessibility standards) and propose investments that make the team faster.

What We're Looking For

• Bachelor's degree in design, human-computer interaction, computer science, or a related field, or equivalent experience.
• 5+ years combined across product design and front-end engineering. You are equally comfortable in Figma and in a modern front-end codebase.
• Experience owning or substantially contributing to a production design system and a Storybook or equivalent component library.
• Strong front-end skills: React, TypeScript, modern CSS including design tokens, and accessibility best practices.
• Comfort with AI-enabled design and prototyping workflows. You see AI as a way to make the design system more useful, not as a replacement for it.
• Strong taste paired with the discipline to systematize it. You recognize good design and codify it into reusable patterns and components.
• Strong written and verbal communication. You can document a pattern, brief a Product Engineer, and influence without authority.
• Self-directed and outcome-oriented. You identify the highest-leverage investments in the system and prioritize without close supervision.
• B2B SaaS or enterprise software experience is a strong plus.
