RF Test and Calibration Engineer

About the role

Quartermaster AI is seeking an experienced Radiofrequency (RF) system Test, Calibration, and Production engineer.

Key Responsibilities

• Establish a highly accurate, efficient, and repeatable RF system calibration capability by defining and implementing end-to-end calibration and test procedures, selecting equipment, and establishing an in-house or contracted lab facility.
• Design, build, and maintain test infrastructure at our DC-area office and future remote/vessel deployment sites.
• Develop and refine Acceptance Test Procedures (ATPs) for execution by technicians for low to medium volume production runs.
• Measure, validate, and document timing accuracy, latency, and phase coherence in RF systems.
• Lead calibration and characterization of system components, including GNSS hardware, antennas, and more.
• Maintain calibration and traceability records, test data packages, and qualification documentation to support internal quality processes and customer/program requirements.

Qualifications (Required)

• 7+ years of hands-on RF testbench experience in a production or advanced development environment.
• High level of proficiency with RF test equipment including VNAs, spectrum analyzers, signal generators, channel emulators, power meters, and associated calibration standards.
• Demonstrated experience building or managing a calibration program.
• Experience writing, owning, and executing Acceptance Test Procedures for production hardware.
• Strong working knowledge of RF system performance parameters: gain, noise figure, IIP3, phase noise, VSWR, spurious emissions.
• Hands-on experience with GPS-disciplined oscillators or other precision timing references.
• US citizenship required.

Qualifications (Preferred)

• Background in sensing systems, maritime hardware, or defense RF systems.
• Familiarity with SDR platforms.
