RF Test

Job Summary

This is a direct, hands-on role requiring extensive experience running RF and microwave lab equipment in a measurement-intensive environment. The position involves working in cryogenic test environments, such as dilution refrigerators, pulse tubes, and cryogenic probers.

Responsibilities

• Deep, practical fluency with precision S-parameter, noise, and time-domain measurements
• Discipline around the operational side of a lab, including calibration cadences, cable and connector hygiene, equipment logs, and documentation
• Track record of running equipment independently and keeping it running without on-site senior supervision
• Comfort operating in a startup environment where priorities shift and procedures are still being written
• Experience with scanning SQUID microscopy or substantive exposure to programs that ran it
• Background supporting SFQ, AQFP, qubit, or superconducting detector measurement programs at a research university, national lab, or industry group
• Time at NIST, MIT Lincoln Lab, Sandia, or a comparable national lab in a cryogenic RF or superconducting characterization role
• Python and scientific computing skills for measurement automation, instrument control, and turning one-off scripts into reproducible measurement pipelines
• Experience with millimeter-wave measurement above 20 GHz, low phase noise characterization, or noise-figure work where uncertainty quantification actually mattered
• EM/microwave simulation experience that you've used to predict and then explain real measurement outcomes
• Evidence of ownership outside the job description: instruments you built, fixtures you designed, methodology you published, or labs you stood up from scratch
• Own day-to-day operation of the Jacksonville RF/cryo test lab
• Execute high-precision RF and microwave measurements on superconducting device samples
• Maintain the instrumentation that keeps those measurements honest
• Define and hold the line on calibration schedules, cable management, fixturing standards, and equipment logs
• Support scanning SQUID microscopy measurement campaigns when required
• Capture, document, and hand off test data to the remote physics team in a form they can actually reason from
• Drive root-cause investigation when measurements disagree with theory or with each other
• Partner with device physicists, fab engineers, and other test staff to keep measurement methodology and process feedback loops tight
