DeepSig is defining the future of wireless communications by merging deep learning with the Radio Access Network (RAN). We are seeking an experienced Technical Lead to architect and drive the development of our next-generation AI-native RAN.

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
• Proven experience in testing telecom network elements, preferably O-RAN DU or similar RAN components
• In-depth knowledge of O-RAN architecture and interfaces (F1, E2, Open Fronthaul, A1, etc.)
• 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
• Strong analytical, problem-solving, and communication skills
• Ability to work collaboratively in cross-functional teams.
