CPI Employment Opportunities

DiFX software developer

Computational Physics, Inc. seeks a physicist, astronomer, mathematician, or other scientist in a closely related field, with knowledge and experience of DiFX correlator software, to support the Earth Orientation (EO) Department at the United States Naval Observatory in Washington, D.C. The EO department operates DiFX (“distributed FX”) correlation software to process long-baseline astronomical radio observations from around the world on a daily basis.  The observations processed are used to determine geodetic parameters, in particular, the current rotation vector of the Earth in inertial space and the precise shape of the Earth.

Salary will be commensurate with experience.

Please send your resume in confidence to employment@cpi.com, and write “DiFX” in the subject line of your email. A cover letter is optional. CPI is an Equal Opportunity Employer.

QUALIFICATIONS

  • Required: experience providing support for VLBI DiFX correlator software.
  • Required: knowledge of astronomy and/or geodesy.
  • Required: background in physics, mathematics or closely related discipline.
  • Highly desirable: knowledge of the DiFX-to-MarkIV software for fringing correlator results.
  • Highly desirable: knowledge of operational software as demonstrated by past work experience, including understanding of standards for coding, testing, and documenting operational software.
  • U.S. citizenship is required.
