Summary
Gregor Ulm is a senior engineering leader with 12+ years of experience building and scaling high-impact systems across fintech, e-commerce, automotive, aviation, and industrial research. He currently directs engineering for Process Management and Modeling at Celonis and has previously led large teams responsible for mission-critical platforms at Delivery Hero, Global Fashion Group, Zalando, and Klarna. Gregor blends a lean, Kanban-inspired delivery mindset with deep technical instincts—having invented a novel linear-time clustering algorithm (RASTER/S-RASTER) and built production tooling like PLC Factory used across the European Spallation Source. He routinely drives measurable improvements in reliability, performance, and cost (e.g., >40% AWS savings at GFG, major throughput gains at Klarna and Delivery Hero) while creating autonomous, high-performing teams. Comfortable in both research and commercial settings, he translates complex requirements into pragmatic, auditable solutions and keeps a hands-on polyglot engineering perspective. Based in Munich, he is as likely to produce a peer-reviewed paper as to ship a low-latency, customer-facing checkout flow.
