Rockstar🎓
Top SchoolRoland Lötscher is a seasoned supply chain and technical sourcing professional with over 20 years’ experience in industrial planning, multisite project delivery across Europe, Asia and the USA, and hands-on ERP optimization (SAP, Syspro, Oracle). He combines deep technical literacy—reading mechanical, electronic and optical plans and familiarity with TCP/IP and data transmission—with strategic supplier negotiation and subcontracting skills to drive cost-efficient sourcing and timely industrialization. A proven cross-functional leader, he has led vision and laser teams into scalable production roles and later managed sourcing and planning at Cohu, translating complex technical requirements into operational solutions. Active in open source as a backend contributor to Xournal++, he applied C++ skills to implement spline tooling for pen-based note-taking software—an uncommon bridge between industrial engineering and software development. Based in Le Locle, Switzerland, he is organized, results-focused and known for clear communication across technical and commercial stakeholders.
