Job description

Job Type
Full-time
Description
Type: Full-Time(W2) On-site/Hybrid, Arlington, VA
We are looking for a skilled test engineer to join our team focused on testing O-RAN DU software and hardware components. The role involves planning, designing, and executing test cases to ensure conformance, interoperability, performance, and reliability of an 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.
Key Responsibilities:
  • Contribute to, 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 an 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 the 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 a related field, or equivalent practical experience.
  • At least 3 years of hands-on experience in a lab, test, or integration role.
  • Familiarity with 4G/5G RAN concepts and 3GPP standards.
  • Proficiency with Python and shell scripting, and experience automating test execution.
  • Comfortable working day-to-day in Linux, with a solid understanding of IP networking fundamentals.
  • Ability to work collaboratively in cross-functional teams.
  • A hands-on troubleshooting instinct: comfortable working with lab hardware, protocol analyzers, and log files to isolate a problem.
  • Self-directed: able to pick up an unfamiliar protocol stack from the specifications and turn a loosely defined test objective into a plan and a set of results with limited supervision.

Preferred Experience:
  • Experience at a RAN vendor, mobile network operator, or test-and-measurement company.
  • Hands-on experience with srsRAN, OpenAirInterface, or other open-source RAN software, or a track record of open-source contributions.
  • Working knowledge of O-RAN architecture and interfaces (F1, E2, Open Fronthaul, A1).
  • Experience with containerization (Docker, Kubernetes), cloud-native environments, and test management tooling.
  • Experience with multi-antenna and/or massive MIMO test setups.
  • Experience with CI/CD tools and automated testing frameworks.
  • Experience testing network software deployed in virtualized or containerized environments on COTS servers (SR-IOV, DPDK, CPU pinning, real-time kernel tuning).
  • Experience with performance and stress testing using RAN test equipment.
  • Familiarity with security testing within telecom environments.
  • Strong analytical, problem-solving, and communication skills.
