• Own the architecture of our CAD plug-ins and the Xviewr desktop application (WPF), and make key technical decisions on design, performance, and scalability




• Build and guide complex applications on NX Open API, Creo Toolkit, and similar SDKs, stepping in hands-on where it matters most
• Design algorithms for parametric modelling, geometry queries, PMI handling, and assembly automation, and set the standards the team follows
• Turn client briefs into technical solutions: lead scoping, effort estimation, and technical proposals together with BD
• Act as the main technical contact for global clients on requirements, design reviews, and escalations
• Set and enforce engineering practices: code reviews, branching strategy, testing, documentation, and release quality
• Work with management on hiring, team growth, and the product technology roadmap
