Test Technician III - RF Verified today

CesiumAstro · Westminster, CO · RF & Comms · first seen 2026-09-03

About the Role

You will work closely with Cesium engineers to create antenna and RF test setups, execute test plans, troubleshoot complex RF systems, and produce timely, reliable test results. You will use and maintain state-of-the-art electronics lab instrumentation, such as anechoic chambers, spectrum analyzers, VNAs, signal generators, oscilloscopes, and automated power supplies. You will identify opportunities for process improvements and help develop efficient, repeatable test methodologies.

The Skylark product line focuses on rapid design, build, and test of cutting-edge active phased array antennas (AESA) for terrestrial and airborne applications. Current programs span high-power, large-scale ground terminals for missile defense to commercial airline and helicopter connectivity solutions.

Many products include active phased arrays with active RF circuitry integrated into the antenna. This adds complexity to the test architecture, including power, digital control, and thermal effects. Direct experience with phased array or AESA testing is strongly preferred.

As a small company, you will wear many hats. You will be comfortable with a dynamic workflow involving multitasking between test setup creation, test execution, equipment maintenance, documentation, lab organization, and cross-functional support activities.

Core Responsibilities

  • Execute RF and antenna test plans and provide concise, accurate, and timely reporting of findings
  • Organize, maintain, and improve antenna testing facilities, equipment, and lab resources
  • Create, own, and troubleshoot setups for sensitive electronics including QFNs, chip-scale ICs, RF cables, and 0201 passive components
  • Build, maintain, and troubleshoot complex RF test setups consisting of instrumentation, cabling, switching, and devices under test
  • Create and provide feedback on detailed documentation with high standards of quality and attention to detail
  • Assist in developing standardized test procedures and improving lab efficiency and repeatability
  • Collaborate with engineering teams to diagnose and resolve RF, power, thermal, and digital integration issues
  • Support calibration, maintenance, and verification of lab instrumentation and equipment

Minimum Qualifications

  • Minimum 3 years of directly related experience as an Engineering Technician or RF Technician
  • Experience working with active electronics and RF systems
  • Hands-on experience with lab instruments such as spectrum analyzers, VNAs, RF signal generators, oscilloscopes, DMMs, and power meters
  • Experience troubleshooting RF systems and interpreting measurement data with minimal supervision
  • Strong problem-solving skills and ability to troubleshoot complex RF systems independently
  • Strong organization skills and ability to manage multiple priorities in a fast-paced environment
  • Comfortable with collaboration tools such as MS Teams, SharePoint, Confluence, and Jira
  • Ability to work well under deadlines and adapt to changing priorities
  • Strong digital, written, and verbal communication skills
  • Ability to read and interpret schematics, wiring diagrams, and engineering documentation

Familiarity with phased array or AESA testing is preferred.
