Job Description
Description
SAIC is recruiting for a Code Manager within our NOAA GFDL program. This individual will be supporting climate code and algorithm transitions to new computing architectures and paradigms, in a structured team environment. The code manager will also participate in various algorithm improvements and code optimization initiatives, as well as serving as a Model Support liaison between Scientists and the Modeling Services team for the purposes of scientific code development. Attending code reviews, planning development meetings, Running Computer Climate Models for the purposes of regression testing and Documentation of production software are other roles included in this position.
Internal modeling software releases are a critical component of a fully-automated workflow, which is an essential capability for keeping long duration simulations executing continuously on large dedicated computer resources. The workflow system is responsible for managing a simulation from onset to completion and delivery of product(s), including: source code and executable management; data transfer and management between disparate sites; batch job creation and submission; post-processing of generated data; and the eventual publishing/distribution to the general public via an externally-accessible repository system. Further, enhancing software development processes through modern techniques such as Continuous Integration (CI) and effective use of Cloud resources is essential to address the emerging challenges posed by community development of GFDL model components.
Specific responsibilities :
· Support MOM6 team outreach activities to the User Community
o Repository management on GitHub
o Respond to and manage pull requests
o Track bugs and issues
· Develop robust unit tests to be used in a continuous integration environment
· Provide software documentation, preferably using UMLs
· Explore cloud computing for Continuous Integration
· Work with Modeling Systems and the MOM6 team to develop, deploy and support a Continuous Integration framework for the NGGPS applications for which GFDL supplies components
o Support integration of source code developed by scientific teams for periodic modeling software releases
o Participate in comprehensive software release testing
· Work with Scientists, Modeling Systems, and Technical Services to diagnose and debug root causes for execution failures
