Profile match
CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.

We are looking to add an Electronics Lab Technician II to our team. If you are excited about working in a startup environment, have a strong work ethic, and are passionate about cutting-edge electronics, we would like to hear from you.

In this position, you will work closely with Cesium engineers to create Antenna & RF test setups, execute test plans, and produce timely, reliable test results. You will have the opportunity to use and maintain state-of-the-art electronics lab instrumentation, such as anechoic chambers, spectrum analyzers, VNAs, Signal Generators, automated power supplies/loads, and more. You will be challenged to propose and fabricate intricate test setups to increase productivity and improve test results.

Many of our products include active phased arrays (a.k.a. active electronically scanned arrays, or AESAs). These are antenna products with active RF circuitry integrated with the antenna. This adds complexity to the test architecture, including power, digital control, and thermal effects. As such, direct experience with phased array (or AESA) testing is preferred.

Core day-to-day activities will include aligning with engineers to test and troubleshoot complex electronics and RF circuitry from component level to system level. As such, the ability to understand and work from drawings, diagrams, schematics, and test procedures is key.

As a small company, the Cesium team “wears many hats.” Candidates should be comfortable with a varied workflow that may involve multitasking between test setup creation, test execution, lab organization, and other related tasks.

JOB DUTIES AND RESPONSIBILITIES

  • Execute test plans and provide concise and timely reporting of findings
  • Organize and maintain antenna testing facilities, equipment and resources.
  • Support setup and measurements of sensitive electronics, including QFNs, chip-scale ICs, RF cables, and 0201 passive components
  • Execute to and provide feedback on thorough documentation with meticulous attention to detail and a high standard of quality
  • Support clean, intricate, and well-documented test setups consisting of instrumentation, cabling, and the devices under test

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

  • Minimum of 2 years of directly related experience as an Engineering Technician
  • Experience working with active electronics
  • Hands-on experience with lab instruments such as DMMs and Power MetersStrong problem-solving skills and ability to troubleshoot with direction
  • Strong organization skills
  • Comfortable with collaboration tools such as MS Teams and Sharepoint
  • Ability to work well under deadlines
  • Strong digital, written, and verbal communication skills
