Software Engineer II-III

Position Description: Position SummaryThe National Radio Astronomy Observatory (NRAO) is an exciting and prestigious research facility that plays a vital role in the study of the universe. The Observatory operates a variety of radio telescopes that span the globe including the famous Very Large Array (VLA) in New Mexico the Green Bank Telescope in West Virginia the Very Long Baseline Array (VLBA) across North America and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. These telescopes are among the most advanced in the world allowing astronomers to explore the universe in unprecedented Next Generation Very Large Array (ngVLA) is a transformative astronomical observatory designed to deliver science-ready data products to a broad community of users. The ngVLA is in the development phase of the project lifecycle. The computing resources needed to support data processing for ngVLA operations is significantly larger and more complicated than any existing NRAO facilities. Therefore NRAO has partnered with the Texas Advanced Computing Center (TACC) to design and prototype the technical infrastructure and data processing software to support ngVLA operations. At NRAO we are recruiting an experienced Scientific Software Engineer to design implement optimize and maintain scientific applications and data-processing software executed on large-scale high-performance computing (HPC) systems. This role will prototype develop benchmark and optimize the Radio Astronomy Data Processing Software (RADPS) in collaboration with role requires demonstrated proficiency in Python and C experience with parallel and distributed computing frameworks and the ability to collaborate closely with domain scientists systems engineers and HPC support personnel. The successful candidate will contribute to the full software lifecycle -- from requirements analysis and algorithmic design through implementation testing optimization and long-term maintainability -- within a performance-critical research-driven position ideally will be based either in Albuquerque NM or Socorro NM but could also be based at our Charlottesville VA or Green Bank WV locations. For well qualified candidates a remote work arrangement may be You Will be DoingThe primary focus of this position will be prototyping profiling and optimizing cutting edge software for RADPS within the Data Processing group.
