TITLE:Physicist, GS-1310, grades 13, 14; $94,520 to $145,205 annually
TYPE OF POSITION: Federal Career/Career-Conditional
DIVISION: - SMA
LOCATION: Cambridge, MA
AREA OF CONSIDERATION: This position is open to all U.S. Citizens or U.S. Nationals.

Note: Federal employees with permanent status or individuals eligible for special appointing authorities may apply to Job Announcement #18-05.

Selection may be made at the 13 or 14 level. Candidates selected at the grade 13 may be non-competitively promoted through review by the Professional Accomplishments Evaluation Committee (PAEC).

Summary: 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.


Duties:

Grade 13:

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.

Grade 14:

In addition to the duties of the grade 13, the incumbent will perform the following:

Lead the implementation of an upgrade path to significantly increase the SMA's observing capacity through improvements in sensitivity.

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.


QUALIFICATIONS :
Basic Requirements:

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

OR

B. 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++.

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.

APPLICATION PROCEDURE: We will only accept applications on line for this position. For complete information about this position and the online application procedures, please visit: USAJOBS
