## Description

We are seeking a Senior System Validation Engineer with a strong emphasis on high-speed SerDes technologies. In this role, you will work across control and data-processing hardware/software, as well as PHY, RF, and firmware elements, to validate a full end-to-end communication system supporting DVB-S2X and additional Radio/IP communication protocols.

This position offers an exciting opportunity to be part of the rapidly changing satellite communications landscape, which is currently undergoing major technological disruption.

 * Execute system-level validation activities covering PHY, hardware, and software components
 * Apply proven expertise in the design, validation, and delivery of high-speed SerDes IP (multi-gigabit link performance)
 * Review system architecture and requirements; contribute to creating thorough test plans with system engineering and other technical teams
 * Develop automated test plans and detailed test procedures for new features and systems
 * Build and maintain test setups supporting both automated regression and manual validation
 * Work hands-on in integration, bring-up, debugging, and enabling new features/products within satellite communication systems
 * Log, investigate, and analyze observed defects
 * Perform root-cause analysis of test failures and collaborate closely with development teams to define corrective actions
 * Support test management tools and maintain involvement in continuous integration practices
 * Conduct detailed data analysis and post-processing of collected measurement results
 * Prepare regular summaries, reports, and performance metrics for test execution
