Celonis is building the trusted platform to industrialize Enterprise AI. The company's Context Model combines process data, business knowledge, and intelligence into a living digital twin that AI can understand, helping enterprises turn operational blind spots into clarity.
You'll join Prisma, a newly formed team building the Modeling Library that powers Celonis' Process Modeling Experiences. This library is the foundation for how users create, edit, and visualize process models across the platform. The team works closely with Product, UX, and other engineering teams to turn complex modeling and graph problems into fast, intuitive interactions for customers.
As a Senior Frontend Engineer on Prisma, you'll help build and grow the Modeling library from the ground up. You'll work on graph rendering, layout, and interaction logic that lets users model business processes clearly and efficiently, even with large and complex datasets.
Key responsibilities:
- Design and build the Modeling library's core components using TypeScript, Angular, and HTML5
- Solve complex visualization problems such as fast interactions, dynamic graph layouts, and graph interactions to Celonis' quality bar
- Use AI coding tools daily to speed up development and problem-solving on graph layout, rendering, and interaction challenges
- Collaborate with Product, UX, and other engineering teams to turn modeling requirements into working features
- Write clean, tested code and contribute to the team's technical decisions
- Own complex visualization or graph-based systems end-to-end
- Drive technical decisions and mentor other engineers
The company is looking for engineers who already use AI coding tools daily and know how to apply them to solve real engineering problems fast, not as a novelty, but as part of how they build production-quality software.

REQUIREMENTS:
- 5+ years of professional frontend engineering experience
- Strong hands-on mastery of TypeScript, Angular, and HTML5
- Track record of owning complex visualization or graph-based systems end-to-end
- Comfortable driving technical decisions and mentoring other engineers
- Proven ability to solve complex visualization problems (fast interactions, dynamic graph layouts, graph interactions)
- Daily, hands-on use of AI coding tools (e.g., GitHub Copilot, Cursor, Claude Code) as part of normal development workflow
- Based in or near Madrid and available to work on-site part of the week (hybrid role)
- Good written and spoken English
NICE TO HAVE:
- Experience with a graph layout library, such as yFiles
