We are advertising for two different positions at the Space Telescope Science Institute (located on the Johns Hopkins University Campus in Baltimore, Md). STScI is seeking Senior Systems Software Engineers to develop applications to calibrate and analyze data from the Hubble and the James Webb Space Telescopes. **************************************************************************** First position: Description The developer will work with other members of the Science Software Branch and instrument scientists to develop applications to calibrate and analyze data from the Hubble Space Telescope and its successor, the James Webb Space Telescope, as well as other astronomy-related projects. The individual will be developing open source applications primarily in Python and C, using open source tools developed at STScI, such as PyRAF and PyFITS, and elsewhere. Some projects may involve developing software applications or libraries as part of a team, or leading a team. Requirements Candidates should have experience writing applications to calibrate, reduce, and analyze scientific data, preferably astronomical data. A background in astronomy and experience with astronomical data reduction is highly desirable. Candidates should have experience writing large programs in a compiled language as well as experience with an interpreted language such as IDL, Matlab, or Python. Experience using array manipulations facilities such as are available in IDL, Matlab, numpy/numarray, or APL is a plus. Experience using software engineering tools such as debuggers, CVS or subversion, and bug trackers is strongly desired. Strong analytical, problem-solving, planning, and organizational skills are needed, and excellent written and verbal communication skills are essential. Prior experience in developing medium or large projects sufficient to demonstrate the specified knowledge, skills and abilities is required. Qualified candidates should possess a Bachelor's degree in a science- related field such as Physics, Astronomy, or Mathematics. A Master's or Ph.D degree is desirable. Substitution of additional relevant education or experience for the stated qualifications may be considered. Apply through the following link: https://www.ultirecruit.com/SPA1004/jobboard/JobDetails.aspx?__ID=*6D48E0EFC... **************************************************************************** Second position: Description The developer will work with other members of the Science Software Branch to help in enhancing and maintaining our Python-based framework for developing astronomical data analysis and calibration applications. STScI has pioneered in the generation of tools for using Python for scientific analysis and programming through its development of PyRAF, numarray, PyFITS, and contributions to other Python Open Source projects. The individual being sought will help STScI maintain its leadership in this area by developing leading-edge capabilities by enhancing existing tools such as PyRAF and PyFITS, contributing to scipy, numpy, and matplotlib, and developing new libraries to meet the needs of future astronomical processing. Some projects may involve developing software tools as part of a team, or leading a team. Work will also require working with an external community on Open Source software projects. Requirements Candidates should be experienced with systems-level programming, preferably with C or C++ and familiar with variances in processor and operating system architectures (preferably Linux, OS X, and MS Windows) with regard to file systems, memory, data types and efficiency, as well as modern software development techniques including Object-Oriented design and programming. Experience with Python and writing C extensions for Python is highly desirable. A working knowledge of any of the following would be a plus: parsers, code generation, numerical techniques, image processing and data analysis, web and network protocols, or parallel processing. Experience using software engineering tools such as debuggers, version control systems (e.g., subversion), and bug trackers is strongly desired. Strong analytical, problem-solving, planning, and organizational skills are needed, and excellent written and verbal communication skills are essential. Prior experience in developing medium or large projects sufficient to demonstrate the specified knowledge, skills and abilities is required. Qualified candidates should possess a Bachelor's Degree in Computer Science, Physics, Math, or technically related field. Master's degree preferred. Substitution of additional relevant education or experience for the stated qualifications may be considered.
