RF Test and Calibration Engineer

About Us:

At Quartermaster AI, we believe the ocean should be a safe and sustainably managed resource for all. By leveraging cutting-edge AI and robotics, we unlock capabilities that were only recently impossible. Our distributed open-ocean systems enable every vessel to sense, compute, and communicate, enhancing maritime domain awareness for those who need it most.

Role Overview:

Quartermaster AI is seeking an experienced Radiofrequency (RF) system Test, Calibration, and Production engineer with deep technical and hands-on experience working with high performance productized radio systems.

You will build from scratch Quartermaster’s antenna and radio system calibration capability, stand up test infrastructure at our headquarters and remote sites, and feed design-for-test requirements back into hardware development. You know what a production RF test lab needs, what it costs, and what breaks at scale.

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

Work Environment:

• Flexible working hours with occasional deadlines requiring high availability.

• Opportunity to work on innovative projects with a global impact.
