Job Summary: We are seeking a skilled 3GPP/O-RAN Base Station Conformance & Performance Test Engineer to join our RAN Systems division. The ideal candidate will focus on validating RF performance for 4G/5G Open RAN-compliant radios integrated with our RAN solutions. This role involves resolving defects, optimizing system performance, and ensuring conformance with industry standards. The position requires deep RF expertise, hands-on experience with lab setups, and advanced testing tools, with sporadic travel required.
Key Responsibilities:
- Collaborate with internal and external teams to set up and configure the Device-Under-Test (DUT), including radio units and subsystems with Layer 1 functionality, as per O-RAN standards.
- Use tools like Keysight or Rohde & Schwarz VSA & VSG to perform Tx and Rx test model verification of channels as defined in 3GPP 36-141 (4G) and 38-141 (5G).
- Design and configure test scenarios, building lab setups based on 3GPP specifications.
- Capture and analyze test logs, working closely with R&D and cross-functional teams for issue identification and resolution.
- Develop and execute test plans, procedures, and setups to ensure products meet performance goals outlined in specifications, internal guidelines, and customer expectations.
- Utilize and expand the capabilities of Intel’s TestMAC tool for radio qualification, providing test vector generation and signal analysis.
- Contribute to the automation of testing processes to enhance efficiency and consistency.
Qualifications:
- Bachelor’s degree in electrical engineering (BSEE) or a related field.
- Strong background in wireless communications, RF specifications, air interface protocols, and proficiency with RF test instruments.
- Knowledge of 2G/3G/4G/5G wireless technologies, RF systems, and networking.
- Experience configuring and operating test setups, including signal generators, analyzers, and channel emulators.
- Familiarity with RF test parameters such as EVM, ACLR, sensitivity, dynamic range, and other key performance metrics.
- 5+ years of wireless industry experience preferred, but not mandatory.
Skills:
- Strong analytical and problem-solving abilities.
- Proficiency in using RF test instruments and conducting basic RF measurements, such as cable loss, noise figure, and power consumption.
- Ability to develop scripts and automate testing processes.
- Excellent communication and teamwork skills, with the ability to collaborate with internal and external stakeholders.
- Ability to travel occasionally during project timelines.
