Work ScheduleStandard (Mon-Fri)Environmental ConditionsLaboratory Setting, OfficeJob DescriptionPosition Summary Thermo Fisher Scientific's Ion Chromatography and Sample Preparation (ICSP) team is seeking a Software Test Engineer III to support validation and performance of next-generation ion chromatography 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 about maintaining or incrementally improving existing solutions, but a complete redesign of a system currently built on approximately 15-year-old electronics. The goal is to create a modern, scalable platform by leveraging new technologies to significantly improve performance, functionality, and overall system architecture. The work involves validating complex 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 validation through to commercialization and sustaining engineering. What will you do? Develop and execute requirements-based test cases for embedded firmware and software Create, maintain, and improve automated test frameworks for embedded and system-level testing Perform bench-level and system-level testing using standard lab equipment Support development of automated test scripts (e.g., Python or similar) Collaborate with engineers to debug and resolve issues across hardware and firmware Document test results and lead structured verification activities Support continuous integration/continuous testing workflows for firmware and software releases Drive improvements test processes and tools Support regression testing and product release activities Education and Experience Bachelor’s and 5+ years of experience in Software Engineering, Electrical Engineering or related field OR or Advanced degree and 3+ years of experience in Software Engineering, Electrical Engineering or related field Knowledge, Skills, and Abilities Understanding of embedded systems and electronics fundamentals Hands-on experience with lab equipment (oscilloscope, multimeter, etc.) Programming or scripting skills (Python or similar) Familiarity with embedded communication protocols (UART, SPI, I2C, etc.) Strong troubleshooting and problem-solving skills Ability to work in cross-functional teams Experience implementing structured development and testing processes Experience with version control systems and CI/CD Experience with test management tools (for example, Jira) Experience working in Agile/Scrum development environments Interest in modern tools, including AI-assisted engineering tools
