The Team

Prisma is 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 our customers.

The Role

As a Senior Software Engineer on Prisma, you'll help build and grow the Modeling library from the ground up. You'll work on the graph rendering, layout, and interaction logic that lets users model business processes clearly and efficiently, even with large and complex data sets.

We're 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.

The work you'll do

• 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

Qualifications you need

• Strong hands-on mastery of TypeScript, Angular, and HTML5
• 5+ years of professional frontend engineering experience
  • A 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 your normal development workflow
• Based in or near Madrid, and available to work on-site part of the week (this is a hybrid role, not fully remote)
• Good written and spoken English

Nice to have

• Experience with a graph layout library, such as yFiles

What Celonis can offer you:

• 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.
