Electronics Engineer III - Sr or Scientist/Research Engineer (Open Ran
Company: National Radio Astronomy Observatory
Posted on: November 15, 2020
The National Radio Astronomy Observatory's (NRAO) mission is to
enable forefront research into the Universe at radio wavelengths.
In partnership with the scientific community, we:
- Provide world leading telescopes, scientific software and
algorithms and expertise,
- Train the next generation of scientists and engineers, and
- Promote astronomy to foster a more scientifically literate
society. The National Radio Astronomy Observatory (NRAO) is seeking
a full-time (at-will) scientific research engineer staff member or
an Electronics E ngineer to specializ e in microwave and millimeter
wave electronics with special emphasis in cryogenic low noise
amplification and mixing . The primary functional du ty (75% time
for Scientist appointments, 100% time for Electronics Engineer
appointments) is to lead our low noise amplifier (LNA) development
team in the multidisciplinary Central Development Laborat ory (CDL)
The Central Develop ment Lab (CDL) is located in Charlottesville,
VA. The CDL has the mission to develop new , science-driven
technology t hat enable s forefront research in radio astronomy.
Current research and development programs include cryogenic,
low-noise front-ends, wideba nd electromagnetic components such as
antenna feeds and polarizers operating from below 1 GHz to nearly 1
THz, phased-array feeds, highly integrated receiver architectures
that employ early signal digitization and novel encoding, wideband
and scalable digital signal processing architectures, and photonic
signal generation, time reference distribution, and data
Job Duties Summary
The selectee will play a leading role in a program of design and
development of low-noise amplifiers for use in astrophysical
observations. A background in designing, analyzing, and building
LNAs from discrete transistors and in designing monolithic
microwave integrated circuits (MMICs) using III-V semiconductor
(e.g. GaAs and InP ) processes is highly desirable.
For a scientific staff appointment , applicants should include a
document in their application package that describes a research
plan for advancing the state-of-the-art in radio astronomy
instrumentation , especially research into advancing the
performance of cryogenic low noise amplifiers and their use in
mixers/down convert ers in radio astronomy receivers . All NRAO
staff scientists have 25% discretionary time to carry out such an
independently-directed research program , with the remaining 75% of
time dedicated to functional responsibilities. The research may be
expansive in nature , but should have synergies with NRAO
facilities /CDL program priorities . Active and e ngaged research
is important as staff scientists are expected to push the
boundaries of current instrumentation capabilities to meet the
emerging requirements of the scientific community.
Work is typically performed in a research or development
environment, but you may occasionally be required to work outdoors.
Some domestic and international travel will be required; must be
willing to travel at regular intervals within and outside the U.S.,
including work at the ALMA array site in Chile at an altitude of
5000 meters .
A Bachelor's degree in electrical engineering, or related field is
required for Electronics Engineer consideration. PhD in Electrical
Engineering with specialization in design of microwave amplifiers
or a Master's of Science in Electrical Engineering with
demonstrated PhD level understanding and accomplishments will be
considered for scientific consideration .
One year or more of experience in design of microwave amplifiers as
part of PhD, post-doctora l or similar level of work for scientific
consideration. A t least 3 years' experience in the field of
microwave circuit design , preferably at centimeter and millimeter
wavelengths, and c orresponding publications for Electronics
Engineer consideration .
- A strong background in cryogenic microwave and millimeter-wave
- A strong background in low noise techniques, and proficiency in
analyzing, designing and synthesizing chipand-wire integrated
circuits (MICs) and monolithic microwave integrated circuits
(MMICs) to implement low noise amplifiers. Experience with high
frequency printed circuits on microwave laminate substrates,
thin-film processes, and waveguide networks.
- Familiarity with active electronic circuits, transistor
modeling, stability factors, and noise parameters.
- Test and measurement experience using Vector Network Analyzers
(including with mm-wave extenders ) , Spectrum Analyzers, Noise
Figure Meters, and Oscilloscopes.
- Proficiency with modern CAD software including circuit
simulation and electromagnetic modeling.
- Familiarity with microfabrication and assembly techniques,
including ultrasonic wire bonding and eutectic die attachment, is a
plus. Application Instructions:
