The EHT is a global network of telescopes that operates at high radio frequencies to directly observe and image the event-horizon region of supermassive black holes at the center of our own and nearby galaxies. In April 2019, the EHT garnered world-wide attention with the publication of the first-ever image of a black hole. Over the next few years the EHT Collaboration expects to improve its observing techniques to enable more agile and more frequent measurements in support of time-domain studies of accretion and relativistic jets, as well as expanding to higher frequencies for sharper images that are less affected by interstellar scattering. The University of Arizona participates in the operation of three EHT telescopes: the Submillimeter Telescope (SMT) on Mt. Graham, the 12-M Telescope on Kitt Peak, and the South Pole Telescope (SPT) in Antarctica, and seeks an enthusiastic R & D Engineer/Scientist to help realize its aspirations. The candidate will be responsible for the preparation for and practical execution of Event Horizon Telescope experiment observations at three radio observatories. The candidate will participate in the setup of VLBI experiments and the observations themselves, and will ensure the collection and analysis of all necessary calibrations and meta-data. They will work with SIS mixer receivers, coherent signal chains, analog and digital signal processing equipment in laboratory and observatory environments. They will improve existing calibration and testing methods and develop new tests, software and/or hardware depending on skills and experience. Outstanding UA benefits include health, dental, and vision insurance plans; life insurance and disability programs; paid vacation, sick leave, and holidays; UA/ASU/NAU tuition reduction for the employee and qualified family members; state and optional retirement plans; access to UA recreation and cultural activities; and more! The University of Arizona has been recognized for our innovative work-life programs.

All new hires subject to the programs will be notified in accordance with adopted Furlough and Furlough-Based Salary Programs guidelines and will be required to comply with all measures. To learn more about the programs and whether this position is affected, please visit Duties & Responsibilities Conduct regular signal path testing of the receiving system for very long baseline interferometry experiments at the Submillimeter Telescope on Mt Graham, AZ, the 12m telescope on Kitt Peak, AZ, and the South Pole Telescope in Antarctica. The signal path includes the hydrogen maser reference, superconducting (SIS mixer) receiver, IF processing hardware, digitization and recording systems. Testing includes receiver sensitivity tests, coherence measurements including phase noise and allan variance, and standard submillimeter telescope calibration measurements. Plan observational procedures and collect necessary calibration measurements. Analyze those measurements and other metadata and deliver to EHT team. Participate in observational campaigns, train telescope operators in the proper use of the VLBI systems in advance of these campaigns, and contribute documentation of the VLBI systems to improve the autonomy of future operations. Develop software to automate testing and operational procedures for the VLBI experiments. The tasks to be automated relate to the system coherence testing, receiver noise and stability testing, digital signal processing hardware characterization, and real-time monitoring of all of these systems. Design and develop new hardware to improve the operation of the VLBI systems at the three telescopes. Conduct testing of RF systems including phase-locked loops, preamplifier systems, spectrometers, and oscillators to evaluate their operability, suitability for use in VLBI experiments. Implement this hardware on site, in collaboration with other observatory engineers and staff. Additional duties may be assigned. Minimum Qualifications * BS degree in electrical engineering, or a related field. – At least 1 year of experience with RF electronics and test equipment such as spectrum analyzers, power meters, and synthesizers. – Computer programming experience. – The candidate must have the ability to work at high altitudes, up to 11,000 feet, and in extreme cold weather conditions. – Experience with or willingness to learn the use of 4-wheel-drive vehicles.
