RF Test Lab Engineer: Calibration, Jigs & Compliance

Praxy; New South Wales; On-site; AUD 90,000 - 130,000; Full time

Job summary

Praxy is seeking a skilled RF Lab Engineer to own lab hygiene and measurement integrity across development and validation environments. You will calibrate and maintain RF test equipment such as VNAs, spectrum analyzers, and signal generators, while measuring and maintaining S-parameters for cables and jigs.

The role requires practical RF calibration knowledge (SOLT/TRL), familiarity with RF connectors, and strong problem-solving skills to minimize artifacts and ensure repeatable results during

Qualifications

• Strong hands‑on RF experience in industry or advanced lab environments.
• Practical understanding of RF calibration techniques (SOLT, TRL, power calibration, etc.).
• Experience measuring and interpreting S‑parameters.
• Familiarity with RF connectors (SMA, MMCX, U.FL, etc.) 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.
