TITLE: Engineering Technician (Electronics), GS-0802, Grade 11; $64,694.00 to
TYPE OF POSITION: Federal Career/Career-Conditional Appointment
DIVISION: - Optical and Infrared Astronomy Division, Fred Lawrence Whipple Observatory
LOCATION: Amado, AZ
AREA OF CONSIDERATION: This position is open to all U.S. Citizens or U.S. Nationals (including Veterans
recruitment). Excepted Service employees may also apply to this announcement. Federal employees with permanent
status or individuals eligible for special appointing authorities should apply to Job Announcement #20-32.
The Engineering Technician (Electronics) position is located at Whipple Observatory (FLWO), Smithsonian
Astrophysical Observatory (SAO). The FLWO is a geographically isolated, technically specialized, and highly
interactive scientific research environment with 24 hour operation; located on Mt. Hopkins within the Coronado
National Forest in Amado, AZ, elevation of ~8600 feet. The FLWO hosts three, meter-class, telescopes and a
number of specialized smaller telescopes.
1. Operates, tests, and maintains the electrical and electro-mechanical systems of the FLWO’s meter-class and
smaller telescopes, their scientific instruments, and related infrastructure. This includes, but is not limited to,
electro-mechanical systems related to telescope dome enclosures and drives, instrument auto-fill LN2 dewar
systems, microwave dishes, network equipment, instrument data collection systems, and moderate and high
dispersion spectrographs; and encompasses the following responsibilities:
a. Monitors telescope observers’ reports, and inspects and tests systems to ensure they are operating
normally so as to minimize data loss and/or downtime.
b. Troubleshoots failures in electronic equipment, telescope mechanical systems and computers, and repairs
or replaces failed components as needed. Examples include electronics that are comprised of digital and analog
circuits from low noise amplifiers to high power servo amplifiers, motion control devices, stepper motors, and
c. Manages dewars to ensure they maintain vacuum and remain at operating cryogenic temperatures at all
times. Ensures the availability of sufficient LN2 on site, and fills smaller instrument dewars from larger tanks.
d. Organizes and maintains an up-to-date system of documentation for instrument and telescope systems and
related maintenance procedures. Documents new procedures as they are implemented.
e. Maintains, cleans, and mounts delicate optical components such as filters, CCD cameras, and
spectrographs. This may require disassembly and assembly of complex, delicate instrument components.
2. Maintains, monitors, services, and upgrades all FLWO on-site computers, data storage, and network
systems. These include computers integral to the telescopes, cameras, camera electronics, and
calibration systems. Identifies and specifies the IT infrastructure needed for efficient operation, ensuring
the compatibility of all on- site computing systems and their adherence to established hardware and
software specifications. Maintains familiarity with IT infrastructure at the MMT Observatory to ensure
mountain wide compatibility, and with software developed for use for scientific analysis to understand
the evolving requirements for the acquisition and storage of large scientific data.
2. Procures and/or builds and maintains the test and support equipment used in the maintenance and operation
of instruments and telescopes.
3. Manages an electronics shop at the telescope site. Ensures that all Smithsonian Institution/FLWO safety
practices and procedures are followed. Identifies requirements, procures, and maintains an inventory of required
tooling and spare parts in order to diagnose and correct instrument/telescope performance anomalies quickly so
as to prevent and/or minimize lost observing time.
4. Conducts regularly scheduled instrument changeovers at FLWO telescopes and participates in the annual
removal and re-installation of mirrors for re-aluminization. Changeovers require using lifting and moving
equipment to remove and replace heavy instruments containing delicate optical systems, and evaluating post-
changeover instrument performance to ensure that all systems are operating without faults or data losses.
Participates in post-aluminization collimation of the telescope(s).
5. Provides instructions and training to visiting astronomers and students on the use of FLWO telescopes and
instruments. Regularly interacts with scientists to obtain their assessment of the quality of the scientific data
collected with the telescopes and corrects any conditions that may have led to data of unacceptable quality.
Qualifying experience for GS-11 includes one year of specialized experience comparable to GS-9 which is
directly related to the work of this position and which has equipped the applicant with the knowledge, skills,
and abilities to perform successfully the duties of the position. For this position, specialized experience is
experience that includes microcontrollers, DC and AC motors and motor control systems, programmable logic
controllers, and electronic detectors such as CCD's.
Experience refers to paid and unpaid experience, including volunteer work done through National Service
programs (e.g., Peace Corps, AmeriCorps) and other organizations (e.g., professional; philanthropic; religious;
spiritual; community, student, social). Volunteer work helps build critical competencies, knowledge, and skills
and can provide valuable training and experience that translates directly to paid employment. You will receive
credit for all qualifying experience, including volunteer experience.
Part-time and/or unpaid experience related to this position will be considered to determine the total number of
years and months of experience. Be sure to note the number of paid or unpaid hours worked each week.
