The Product Development Scientist/Engineer ensures scientific instrumentation developed by R&D performs reliably throughout its intended scientific and product lifecycle applications. This is a product-development role, not a sales applications role. The position connects engineering performance with real-world product performance across scientific use, manufacturing, quality control, service, and other lifecycle activities. The role evaluates whether the complete product performs as intended, develops and executes application-level studies, interprets instrument and measurement-system behavior in context, and works with engineering teams to identify the source and significance of performance limitations, variation, and unexpected results. It provides experimental evidence and application understanding to support product requirements, performance claims, release decisions, and continued improvement. The role is an independent contributor and member of multiple teams. Domestic or international travel to other Anton Paar facilities may be required at less than 5%.
