We are looking for a skilled test engineer to join our team focused on testing the O-RAN DU software and hardware components. The role involves planning, designing, and executing test cases to ensure conformance, interoperability, performance, and reliability of O-RAN DU in compliance with O-RAN Alliance and 3GPP specifications. The candidate will work closely with development, integration, and network teams to validate DU functionality within the O-RAN architecture.

What You'll be doing

• Design, develop, and execute test plans, cases, and scripts for O-RAN DU software and related interfaces
• Perform conformance testing to verify compliance with O-RAN and 3GPP standards
• Conduct interoperability (IOT) testing between O-RAN DU and other network elements such as O-CU and O-RU
• Execute end-to-end (E2E) testing scenarios to validate the complete O-RAN communication chain
• Identify, log, and track defects; work collaboratively with development teams to resolve issues
• Automate test cases and contribute to CI/CD pipelines to support continuous testing
• Validate performance metrics and key performance indicators (KPIs) to ensure DU meets required standards
• Participate in site commissioning and integration support
• Prepare detailed test reports, documentation, and provide feedback for product improvements
• Stay updated with latest O-RAN Alliance releases, specifications, and testing methodologies.

Required Qualifications:

• Bachelor’s degree in Telecommunications, Electrical Engineering, Computer Science, or related field

• Familiarity with 3GPP NR standards and protocols
• Strong skills in test automation, scripting languages (Python, Shell, etc.), and test management tools
• Experience with virtualization, containerization (Kubernetes, Docker) and cloud-native environments
• Good understanding of network protocols (TCP/IP, UDP) and Linux operating systems
• Ability to perform troubleshooting using RAN test equipment, protocol debuggers, and logging tools
• Ability to work collaboratively in cross-functional teams

Preferred Experience:

• 6 plus years experience at a Tier-1 OEM or US MNO is highly valued
• Massive MIMO testing experience is must
• Experience with CI/CD tools and automated testing frameworks
• Experience of NFV, SDN, and virtualized RAN (vRAN) test experience is a plus
• Hands-on experience with performance and stress testing using RAN test equipment
• Familiarity with security testing within telecom environments
