RF Test and Calibration Engineer

ROLE OVERVIEW:

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

You will build Quartermaster’s antenna and radio system calibration capability (in-house or contracted), 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:

- Calibration program ownership: Establish NIST-traceable (or equivalent) calibration capability for Matsu SDR systems. Define procedures, select equipment, and set up an in-house lab or manage contract labs end to end.

- Test infrastructure: Design, build, and maintain RF test infrastructure at our Northern Virginia office and future remote/vessel deployment sites. Own the equipment inventory, maintenance cycles, operational readiness, and coordination with hardware and software teams.

- Design-for-test input: Participate in hardware design reviews. Define testability requirements, component tolerance specs for our radio systems, peripheral hardware (e.g. GPSDOs), and custom assemblies.

- Automated acceptance testing: Develop and own Acceptance Test Procedures (ATPs) for execution by technicians for medium to high volume production runs. Automate where practical; define pass/fail criteria that catch previous and potential failure modes.

- Timing and signal chain characterization: Measure and validate timing accuracy, latency, and phase coherence across the full system. Document performance margins against system requirements.

- Component and subsystem validation: Lead calibration and characterization of system components, including GNSS hardware, antenna patterns, and more. Define the measurements, execute or delegate, and own the traceability records.

- Environmental testing: Define and execute (or ou...
