Software Test Engineer

Position Summary

ThermoFisher Scientific's Ion Chromatography and Sample Preparation (ICSP) team is seeking aSoftwareTest Engineer III to support validation and performance of next-generation ionchromatography laboratory instruments. 

This role is part of a strategic NPI (New Product Introduction) initiative focused on developing a new generation platform for chromatographic instruments. This is not aboutmaintainingor incrementally improving existing solutions, but a complete redesign of a system currently built onapproximately 15-year-oldelectronics. 

The goal is to create a modern, scalable platform byleveragingnew technologiesto significantly improve performance, functionality, and overall system architecture. The work involvesvalidatingcomplex analytical instrumentation systems that combine advanced hardware, embedded software, and domain-specific capabilities. 

This is a multi-year program, offering long-term stability and the opportunity to contribute across multiple phases of development—from early validationthrough tocommercialization and sustaining engineering.
