Job summary

Morse Micro, Australia’s leading semiconductor company building Wi-Fi HaLow chips for IoT, seeks an RF Calibration & Lab Technician to uphold lab hygiene, calibrate RF test equipment, and ensure repeatability of RF measurements. You will work across Hardware, DVT, Systems, and SVT teams to maintain high standards of data integrity and device validation.

The role emphasizes hands-on calibration, S-parameter work, and robust documentation in a dynamic lab environment.

Qualifications

• Strong hands-on RF experience in industry or advanced lab environment.
• Practical understanding of RF calibration techniques (SOLT, TRL, power calibration).
• Experience measuring and interpreting S-parameters.
• Familiarity with RF connectors (SMA, MMCX, U.FL) and proper torque practices.
• Experience troubleshooting measurement inconsistencies and identifying root causes.
• Comfortable working with high-frequency PCB assemblies and RF modules.
• Strong documentation habits and disciplined working style.

Responsibilities

• Own RF lab hygiene and measurement integrity across development and validation environments
• Calibrate and maintain RF test equipment including VNAs, spectrum analyzers, signal generators, power meters, and associated accessories
• Measure and characterize cable, connector, and jig S-parameters (S11, S21, etc.) and maintain correction data where required
• Establish and enforce best practices for RF handling (torque wrench usage, connector care, cable replacement schedules, labeling, ESD discipline)
• Debug and optimize RF test setups to eliminate measurement artifacts and improve repeatability
• Manage lifecycle of cables, connectors, adapters, and fixtures. Identify and replace degraded interconnects before they impact data quality
• Support DVT, SVT, and Systems teams during bring‑up, validation, and regulatory testing
• Maintain calibration logs, test setup documentation, and lab asset tracking
• Work with engineering teams to improve test fixture design and measurement robustness
