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.
