Receiver Engineer
Aug 2007
Location: Owens Valley Radio Observatory
Open until filled
Caltech is seeking a recent graduate in physics or engineering to assist with the
construction and testing of a new generation of millimeterwave receivers for CARMA.
The position is based at the Owens Valley Radio Observatory.
This is an opportunity for an exceptional engineer to work on cutting edge
projects in a unique location in the midst of a great outdoor recreation area.
The successful candidate will be expected to assist with the assembly
and testing cryogenic receiver systems based on superconducting (SIS)
mixers. This work will be carried out under the general direction of
senior staff, but the candidate must also have the ability to work
independently. CARMA is in a state of continual evolution and there are
opportunities for a capable and enthusiastic applicant to contribute
significantly in other areas. This person will also be expected to
improve and maintain current receiver systems for astronomical
observations.
Candidates should have recently obtained a BS or MS in
Electrical Engineering or Physics. A strong interest in experimental
work is required, and knowledge of any of the following areas would be
useful assets: microwaves, cryogenics, detectors, and noise
measurements. Experience in PC data acquisition, particularly using
LabVIEW, would be advantageous.

Assistant Cryogenics Engineer
Aug 2007
Location: Owens Valley Radio Observatory
Open until filled
Caltech is seeking an individual to maintain cryogenic refrigetration
systems at its Owens Valley Radio Observatory. There are about 25 such
systems used to cool sensitive astronomical millimeter-wave receivers.
It is expected that this person will monitor
performance, diagnose and fix problems, and plan for replacements and
upgrades. As time permits this person will also help with other
receiver, telescope and facilities operations and maintenance.
Preference will be given to candidates with experience
in diagnosing and fixing closed-cycle cryogenic refrigerator systems,
but we will consider applicants who have demonstrated abilities in
mechanical or conventional refrigeration areas, good problem solving
skills, and a willingness to learn techniques for cryogenic systems. A
systematic and meticulous approach to maintaining systems and records
is essential, and knowledge of PCs, and basic physics or electronics
would be helpful.
Work will be split between facilities at OVRO in the
valley and at the CARMA array site at Cedar Flat in the Inyo Mountains,
20 minutes from OVRO. It will be coordinated with other engineers
working on the receiver and telescope systems. Once familiar with the
systems, it is important that this person be able to independently
carry out most of the above tasks while also working in a distributed
team that is focused on operating and maintaining the array.

Software Engineer
Sept 2007
Location: Owens Valley Radio Observatory
Open until filled
Caltech is seeking a software engineer to development and maintain
software for CARMA.
The position is based at the Owens Valley Radio Observatory.
This is an opportunity for an exceptional engineer to work on cutting edge
projects in a unique location in the midst of a great outdoor recreation area.
Primary duties will include designing, developing, installing and
maintaining software for a new digital correlator system.
Other duties will include work on software for the interferometer
control system.
Candidates must have strong programming skills in C++ and
experience with Unix.
Candidates must also be organized, flexible, and comfortable
with the constant change that accompanies scientific research.
Candidates should be able to work well both individually and
in a team environment.
This position requires a BS/BA in Computer Science,
Engineering, Physics, or Astronomy and 2 to 4 years programming experience.

About CARMA
CARMA consists of 15 telescopes designed for aperture synthesis
imaging of spectral lines and radio continuum emission in the 1.3 and 3
mm atmospheric windows. By 2008, baselines to 1.9 km will provide
sub-arcsecond (0.15") imaging. Observational programs include studies
of nearby regions of star formation and mapping molecular gas in
galaxies.
OVRO's location The Owens Valley Radio Observatory (OVRO)
is located in the scenic Owens Valley on the east side of the Sierra
Nevada mountains, 10 miles south of Bishop, California. OVRO is located
within 15 miles of the CARMA observing site, Cedar Flat. Bishop is a
small community surrounded by National Parks and wilderness areas and
is ideally located for people interested in outdoor sports ranging from
fishing to winter mountaineering. |
