Job description

Senior System Validation Engineer – SerDes Focus

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.

Responsibilities

• 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

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering

• 5+ years of experience in system validation

• Strong experience validating complex HW/SW/embedded systems in a lab environment

• Solid understanding of RF physical‑layer testing with hands‑on use of RF lab instruments (Spectrum Analyzers, VNAs, Signal Generators, power meters, high‑speed scopes, etc.)

• Experience developing automation for validation workflows; proficiency in programming languages such as Python, C#, C++, etc.

• Experience testing IP networking systems (routers, network processors) with good knowledge of IP communication protocols and network performance behavior

• Background in planning, estimating, and developing comprehensive system tests

• Familiarity with defect‑tracking and documentation platforms (preferably JIRA and Confluence)

• Strong self‑learning ability and adaptability to new technologies

• Independent, highly motivated, capable of multitasking, and a strong team player

• Excellent interpersonal and communication skills
