Job Description


The GFDL Vortex Tracker is a software package that analyzes the output of computer weather models to diagnose the forecast tracks and intensities of tropical cyclones and provide output that is used as forecast guidance for hurricane forecasters and emergency managers.  This vortex tracker has been the de facto standard for decades and is used widely within the atmospheric sciences community.  It is used both for operational forecasting applications as well as for use in evaluating the tropical cyclone forecasting capabilities of models that are being used in the research & development process.  The tracker is written primarily in modern Fortran and can read model output that is encoded in either GRIdded Binary (GRIB) format (Versions 1 and 2) or in NetCDF format.  It can handle data from both global and regional models, including regional models that have moveable grids.  

 Previously, the tracker was distributed by the NCAR Developmental Testbed Center as a simple tar-archive download under Hurricane Forecast Improvement Project funding. As the last release from DTC occured in 2018 and user support ceased in 2021, the individual use versions have diverged from a common codebase.  There is a need to coalesce the various individual updates into a single stream and establish the GFDL Vortrex Tracker as a community-developed GitHub project adhering to accepted standards.  

 We are looking for an early- to mid-level career individual to help manage our efforts in developing and maintaining the GFDL Vortex Tracker GitHub community repository.  This individual needs to have some experience with programming in a language such as Fortran, Python, or C. 

 The specific responsibilities include, but are not limited to:

  •  Support GFDL outreach activities to the user community:
    • Repository management on GitHub
    • Respond to and manage pull requests
    • Track bugs and issues
    • Enforce coding standards and style guidelines
  • Create and maintain automated build system for the tracker, including any necessary libraries
  • Develop and maintain unit tests for use in a continuous integration environment
  • Ensure and extend compatibility with key community supported platforms and compilers
  • Participate in comprehensive software release testing
  • Coalesce all divergent tracker versions into a single supported vortex tracker
  • Work collaboratively with developers to fix bugs and/or develop enhancements in modern Fortran
  • Support merging and integration of source code developed by scientific teams for periodic software and/or public releases
  • Assist in creating and maintaining documentation
  • Promote community development via issue tracking
  • Respond to queries from the user community:
    • On the compilation, setup and use of the tracker
    • On issues with running the tracker
  • Work collaboratively with the EPIC program to
    • Schedule cross-project pull requests
    • Inform community of GFDL release schedules
  • Provide a containerized version of the tracker for cloud and other non-standard environments


·  B.S. in Math, Computer Science, Engineering or Physical Science e.g. (Meteorology, Physics) and 2+ years of related experience (advanced degree can be substituted for experience)

·  Proficiency in Linux and basic Linux administration - Proficiency in Modern Programming Languages e.g. (C, C++)

·  Experience managing code and repositories

·  Candidate must be willing to learn other languages e.g. FORTRAN - Demonstrated ability to learn new programming languages and technical skills

·  Professional knowledge in one or more physical science fields

·  Experience with source code control systems i.e. code repositories e.g. SVN, GIT 

·  Technical Writing Experience

·  Good communication skills
