Job Details

Hiring Agency:  SMITHSONIAN ASTROPHYSICAL Observatory
Position Title:  Physicist
Open Period:  12/20/2017 - 01/31/2018
Series/Grade: GS - 1310 13/14
Salary:  $94,520 -  $145,205
Promotion Potential:GS-14
Duty Location(s): 1 Vacancy in Cambridge, MA
 
The Smithsonian Astrophysical Observatory (SAO), is seeking a Physicist at it's Cambridge, MA location.  Current developments, designated “wSMA” are underway to further enhance the sensitivity of the Submillimeter Array (SMA) by increasing the bandwidth of the receivers, augmenting the data transmission system, possibly changing to a digital optical data transmission, and in due course replacing the “SMA Wideband Astronomical ROACH2 Machine” (SWARM) with wider bandwidth, more compact, and lower power equipment.
 
The selected candidate will play a leading role in implementing an upgrade path to significantly increase the SMA’s observing capacity through improvements in sensitivity.  Contribute to the definition of the optimum architecture for digitally correlating and phasing the ultra-wide bandwidth output of upgraded wSMA front-ends across the array’s eight antennas.
 
Make key contributions to the detailed design, construction, testing and commissioning of the wide-bandwidth high spectral resolution correlator with phased array capability for Very Long Baseline Interferometry (VLBI).

Develop Field Programmable Gate Array (FPGA) configuration codes (“gateware”), using hardware description languages such as VHDL or Verilog, and Matlab-Simulink.  Responsibilities extend to writing higher level layers of control software in object-oriented languages such as Python and C++.  Also develop digital signal processing codes for GPU processors in languages such as CUDA and OpenCL

Formulate and conduct original scientific research using the SMA, and other instruments as appropriate.  Prepare results of scientific and technical developments for publication in professional journals and for presentation at engineering or scientific conferences and technical symposia.  Participate in review meetings covering technical and scientific research and development.

Requirements

Qualifications:
  1. Degree: physics; or related degree that included at least 24 semester hours in physics.

    or

  2. Combination of education and experience -- courses equivalent to a major in physics totaling at least 24 semester hours, plus appropriate experience or additional education.
In either A or B above, the courses must have included a fundamental course in general physics and, in addition, courses in any two of the following: electricity and magnetism, heat, light, mechanics, modern physics, and sound.

In addition to Basic Requirements above, you must meet one of the following:

GS-13: One year of specialized experience (Federal or other) equivalent to the GS-12 level that is similar to the work of this job.  This will include activities such as advanced complex digital signal processing instrument design, including architectural definition.  Such instruments should use high performance Field Programmable Gate Arrays (FPGAs) and Graphics Processing Units (GPUs). An advanced level of experience in hardware description languages such as VHDL or Verilog, and MATLAB-Simulink, GPU programming in CUDA or OpenCL and in real time object oriented programming in languages such as Python or C++.    

GS-14: One year of specialized experience (Federal or other) equivalent to the GS-13 level that is similar to the work of this job.  This will include activities such as expert level complex digital signal processing instrument design conducted independently, including advanced architectural definition.  Such instruments should use high performance Field Programmable Gate Arrays (FPGAs) and Graphics Processing Units (GPUs). An expert level of experience in hardware description languages such as VHDL or Verilog, and MATLAB-Simulink, GPU programming in CUDA or OpenCL and in real time object oriented programming in languages such as Python or C++.
