CesiumAstro is an aerospace technology company headquartered in Austin, Texas, and founded in 2017. The company develops and manufactures software-defined active phased array communication systems, including satellites, terminals, and reconfigurable processing units for space, airborne, and ground missions. It serves commercial and defense sectors with high-throughput connectivity solutions and operates manufacturing facilities in the United States to support domestic supply chains.

We’re seeking a Senior Antenna Test Engineer I with experience in RF anechoic chamber measurements and Antenna characterization to join our Test Engineering team. You’ll work closely with RF, antennas, and systems engineers to define, execute, and analyze antenna measurement campaigns - including radiation patterns, gain, efficiency, polarization, and over-the-air performance - using state-of-the-art chamber setups.

JOB DUTIES AND RESPONSIBILITIES

  • Plan, setup, and execute antenna and RF measurement campaigns in anechoic chambers, including Near-Field and far-field radiation patterns, gain, efficiency, and polarization characterization.
  • Perform VNA calibration and measurement, spectrum analysis, and signal generation.
  • Align, position, and configure devices under test (DUTs), reference antennas, and positioners to maximize measurement fidelity.
  • Develop, refine, and document test procedures, setups, and data and test analysis scripts.
  • Collaborate with design and systems teams to troubleshoot anomalies and product development.
  • Manage and maintain chamber instrumentation, cables, and ancillary RF equipment.
  • Develop custom test code, to enhance test performance and reduce test time.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

  • Bachelor of Science (BS) or higher in Electrical Engineering, Physics, or a related field.
  • 4+ years of experience in RF testing, with significant hands-on experience in anechoic chamber antenna measurements.
  • Proficient with Vector Network Analyzers (VNA), spectrum analyzers, signal generators, and associated RF instrumentation.
  • Demonstrated ability to perform pattern measurements, gain and efficiency extraction, and polarization characterization.
  • Strong understanding of RF fundamentals: matching, S-parameters, near field and far-field measurements, and chamber effects.
  • Experience with automated test procedures and data processing (Python and C#).
  • Excellent written and verbal communication skills, with attention to detail in documentation and reporting.

PREFERRED EXPERIENCE

  • Experience with phased array testing, antenna and phased array troubleshooting, and OTA testing.
  • Antenna design experience.
  • Familiarity with NSI control software and positioner automation.
  • Prior aerospace or satellite RF test experience.
