• Experience in OTA testing, RF measurements, antenna systems, or wireless test system integration.
• Understanding of MPAC OTA methodologies and validation procedures (e.g. quiet-zone characterization).
• Knowledge of RF systems, antenna theory, calibration methods, and measurement instrumentation.
• Familiarity with chamber hardware such as probes, positioners, and RF subsystems.
• Experience with EMC/EMI requirements and RF-safety considerations is an asset.
• Strong understanding of 3GPP RAN protocols and procedures (e.g., NR/LTE PHY/MAC), including scheduling, link adaptation, and mobility management.
• Expertise in beamforming and massive MIMO techniques, including beam management procedures and their validation in OTA environments.
• Ability to work in cross-functional engineering teams.
• Strong analytical and problem-solving capability.
• Good communication skills and comfort in customer-facing situations.
• Hands-on and proactive approach to system integration and validation.

Responsibilities

• Translate customer use cases to operational OTA test solutions.
• Design and implement functional and performance test solutions by integration of protocol stack and channel emulation into OTA chamber environments.
• Plan MPAC OTA system configurations RF validation approaches.
• Define OTA chamber requirements, including quiet-zone performance, absorber characteristics, and structural needs.
• Specify probe antennas, positioners, RF cabling, and related chamber hardware.
• Support installation, alignment, and RF integrity checks of chamber components.
• Verify OTA system functionality, including chamber control, positioner performance, and test automation.
• Measure and evaluate RF-quality metrics such as quiet-zone characteristics, field uniformity, and phase flatness.
• Define and verify EMC, grounding, shielding, and other compliance-related requirements for high-power BS testing.
• Ensure that system meets regulatory and internal safety standards.
• Present OTA solutions to customers and support solution introduction and commissioning.
• Collect customer requirements and translate them into actionable engineering specifications.
• Provide technical troubleshooting and system-level support.
