AP089 Scientific Software Developer – HEASARC and TESS

NASA GSFC hosts several mission support teams, who interface with scientists and the general public. These support teams help users work with data from missions such as TESS, Swift, Fermi, and more. At NASA, scientists and domain experts have built several open-source packages which the community relies on to access and analyze data. For example, the Lightkurve Python Package is used by hundreds of astronomers and members of the public to work directly with TESS data. The heasoftpy package aims to provide Python routines for high energy astrophysics HEASoft software. These packages are built and maintained by scientists. We are seeking an individual with experience in Python development to join the team to assist in redesigning, improving, and maintaining existing packages, and to help build new scientific packages at NASA GSFC, alongside a team of scientists.
