Senior Design Engineer, AI-Powered Design Platform

About the role

Celonis is looking for a Senior Design Engineer to build the internal tooling, automation and agent-pipeline infrastructure behind its design practice. The role sits at the intersection of design, engineering and product: you will design and build usable tools for designers, engineer the pipeline that connects the design system to AI coding agents, and govern how AI is used safely and measurably. It is a senior, hands-on position for someone who designs and builds tools.

Key responsibilities

• Design and build internal tools and automations with strong UX, using TypeScript/JavaScript, Python, APIs and the Figma plugin/REST APIs.
• Engineer the agent pipeline: set up and maintain MCP servers, context pipelines and integrations connecting the design system to AI coding agents (Cursor, Claude Code, v0, Copilot).
• Automate governance-as-code: build CI checks, release automation and policy enforcement so standards are guardrails in the pipeline.
• Own and govern the AI tool stack: evaluate, integrate, license and roll out tools, partnering with security and legal on data/IP review and human-in-the-loop checkpoints.
• Build telemetry and dashboards for design-system and AI-tool adoption, cycle time and quality.
• Collaborate with designers, PMs and engineers to evolve the design system and its workflows, and build reusable prompts, specs and starter kits.
• Set tooling and operations standards, lead platform initiatives and mentor designers and engineers.

Required profile

• Around 5-8 years in design engineering, front-end, design-systems tooling or platform/internal-tools engineering, with genuine design/UX sensibility.
• Good UX instincts and a track record of improving how a design or product team works through tooling and automation.
• Fluency with AI tooling and a thoughtful, responsible approach to governing it.
• Strong product mindset, ownership and the communication and leadership of a senior individual contributor.

Required skills

• TypeScript/JavaScript and/or Python, APIs, CI/CD and integrations.
• Solid working knowledge of Figma at an organizational level and its plugin/REST APIs.
• HTML/CSS foundation; bonus: design tokens, Code Connect, Angular/TypeScript and CSS custom properties.
• Bonus: MCP server experience, AI tool governance, telemetry dashboards, and background in complex B2B or data-heavy environments.

What we offer

• Restricted Stock Units (RSUs) and merit-based refresh grants.
• Parental leave: 24 weeks fully paid for primary carers and 12 weeks for supporting carers.
• Unlimited PTO in applicable regions and a flexible hybrid work model.
• Learning through a 70-20-10 framework, mentorship and a dedicated learning platform.
• Wellbeing support, including Wellhub membership, mental health counseling and Wellness Weeks.
• Paid time off for volunteering in Impact Days.
