VLBA Specialist I-II (4313)

Engineers, Technical Specialists and Technicians Los Alamos, New Mexico


Position Description:


Position Summary

The Long Baseline Observatory has an full-time opportunity for a VLBA Station Specialist at our site in Los Alamos, NM.  The VLBA Station Specialist is responsible for installation, repairs, and maintenance at the Very Long Baseline Array Station, which includes the 25-meter antenna and support equipment. The station is part of a 10 antenna array, spread across the US, and captures radio astronomical data that are then delivered to a correlator elsewhere. The Specialist must respond to emergency repair situations as dictated by the impact on the station's ability to perform intended functions. The employee works with another Specialist, occasionally solo when schedule issues arise, and is on-call on alternating weekends. 


In addition to competitive pay, NRAO provides excellent paid time off benefits (vacation and sick leave). Medical, dental and vision plans are effective first day of employment. NRAO’s retirement benefit contributes an amount equal to 10 percent of a qualified participant’s base pay. No contribution is required of the employee; we also offer an optional supplemental, tax-deferred plan for employee retirement contributions.
