This position is working on the Amentum JETSII contract. This position will focus on developing, deploying and optimizing software for use in the Flight Sciences Lab (FSL) and other NASA HPC resources.

The Flight Sciences Lab (FSL) is one of Johnson Space Centers primary HPC labs and hosts a wide variety of analyses, which support almost all the major programs at NASA including the International Space Station (ISS), Orion, Space Launch System (SLS), Commercial Crew Program, Moon Base, Human Landing System (HLS), and many others. The FSL systems are currently comprised of over 800 nodes, 26,000 cores, and 10 PB of storage, which serve over 1000 users.

• Partner with FSL Users to evaluate and optimize the software development practices of the group, and ensure success of the project.
• Participate in the planning and major development efforts on software engineering projects for flight software, Guidance and Navigation, and analysis.
• Work closely with partners and external contractors to meet their software requirements and address bugs.
• Act as a mentor for good software development and engineering in HPC environments.

• Typically requires a minimum of a bachelor's degree in Engineering and normally possess 5-10 years of related experience. License and certification may be required.
• A minimum of a BS degree in computer science or engineering and 4+ years of software engineering experience outside of degree.

• 6+ years of experience in addition to the degree.
• Experience developing software for use in HPC environments.
• Experience with Monte Carlo type workflows and optimizing them for use in HPC environments.
• Experience with Trick based simulation workflows, and related toolsets.
• Experience with modern software practices such as test‑driven development, Agile software development practices, the use of generative AI coding assistants, and a firm, proven knowledge of software development life cycles.
• Experience integrating C++, Fortran, Python, and shell‑based workflows in HPC or simulation environments.
• Demonstrated Experience with MPI based workflows.
• Activity within the broader open‑source software community.
• Demonstrated Experience with Podman and HPC environments.
• Demonstrated Experience with Gitlab and Jenkins tools.

• Excellent personal and professional career growth
• 9/80 work schedule (every other Friday off), when applicable
