Senior Design Engineer, Design System

At Celonis, design has to scale across a complex, enterprise-grade process intelligence platform, and increasingly, it has to scale to machines as well as people. AI coding agents now generate a growing share of the UI our engineers ship, and our design system is the contract that keeps that output on-brand, accessible, and consistent.

This role sits at the intersection of design, engineering, and product, with a strong emphasis on craft, usability, and scalability. You'll design and build the system itself, owning interaction decisions and front-end architecture, and translating complex process data and AI-driven behaviors into intuitive, high-performance experiences. It's a senior role: you'll often operate with minimal design oversight, set standards, lead initiatives, and mentor others while staying deeply hands-on in both design and code.

• Design and build production components in Angular and TypeScript, our design system is built in Angular and we may adopt React over time, on a foundation of rock-solid HTML and CSS (semantic markup, ARIA, and modern CSS custom properties driving design tokens).
• Own interaction decisions, component design, and front-end architecture end-to-end, independently translating ambiguous requirements into thoughtful, usable UX.
• Translate complex process-intelligence data and AI-driven behaviors into clear, intuitive, high-performance operator experiences.
• Set the technical and craft standard for front-end quality, polish, motion and animation, performance, and accessibility, across the team.
• Drive rapid prototyping to explore novel interaction concepts and turn ambitious design visions into distinctive, testable experiences.
• Collaborate with designers, PMs, and engineers to derive and evolve the design system through a healthy contribution model.
• Make the system agent-ready: maintain tokens-as-code in the W3C DTCG format (Style Dictionary or similar) and structure component metadata, docs, and APIs so AI coding agents can consume them as reliable context.
• Author and maintain Figma Code Connect mappings so Figma components link cleanly to their coded counterparts for engineers and agents alike.
• Build evals as guardrails, visual-regression, accessibility, and token-compliance checks in CI, so generated and contributed UI meets the bar before it ships.
• Use AI tooling daily (Figma Make, v0, Cursor, Claude Code, Copilot, or similar), applying senior design and engineering judgment to critique and correct the output.
• Lead system initiatives and mentor designers and engineers contributing to it.

• Around 5–8 years across design engineering / UX engineering / front-end, including significant hands-on work building a design system or component library in a SaaS or B2B environment.
• Excellent UX instincts with strong attention to interaction detail and usability, you can own design decisions independently, with minimal oversight.
• Strong production front-end skills in Angular and TypeScript with rock-solid HTML and CSS fundamentals; experience with (or genuine openness to) React is a plus.
• Deep understanding of design token architecture (primitive → semantic → component tiers) and modern token pipelines.
• Strong Figma fluency and comfort moving fluidly between design and code.
• Demonstrated accessibility expertise (WCAG 2.2) implemented in code.
• Hands-on fluency with AI design and coding tools, and an opinionated, responsible point of view on using them.
• A strong product mindset and bias toward ownership, plus the communication and leadership of a senior IC.
• Experience with Figma Code Connect in production.
• Experience building or integrating MCP (Model Context Protocol) servers e.g. the Figma Dev Mode MCP server or a custom design-system MCP server.
• Experience building evals for AI-generated UI, or writing specs/prompts for AI generation.
• Background working on complex, data-dense, or real-time interfaces (a strong fit for our process-intelligence product).
• Token-pipeline experience with Style Dictionary, Tokens Studio, or equivalent.

• Pioneer Innovation: Work with the global leader in Process Mining and the Process Intelligence Graph to shape the future of AI-driven business operations.
• Ownership from Day 1: Every full-time "Celonaut" is an owner, receiving Restricted Stock Units (RSUs) and merit-based refresh grants.
• Unrivaled Family Support: Benefit from our inclusive parental leave policy—24 weeks of fully paid leave for primary carers and 12 weeks for supporting carers, available from your first day of employment.
• Work-Life Integration: Enjoy Unlimited PTO (in applicable regions) and generous PTO globally, as well as a flexible hybrid work model that balances remote focus with vibrant office collaboration.
• Continuous Growth: Elevate your skills through our 70-20-10 learning framework, mentorship programs, and access to a dedicated learning platform.
• Holistic Well-being: Prioritize your health with subsidized Wellhub memberships, mental health counseling, and dedicated "Wellness Weeks" that prioritize work/life balance.
• Drive Sustainability: Participate in annual Impact Days, where you receive paid time off to volunteer for community and environmental causes with your local office, or virtually.
• Global Inclusion & Belonging: Find community through our Inclusion Think Tank and participate in our annual Inclusion Days, ensuring every voice is heard and valued.
• Value-Driven Impact: Join a mission-led organization where our core values—Live for Customer Value, The Best Team Wins, We Own It, and Earth Is Our Future—drive every decision.
