The Vera C. Rubin Observatory, now under construction, will be a large-aperture, wide-field, ground-based telescope-camera-data processing system that will digitally survey half the sky every few nights in six optical bands. It will explore a wide range of astrophysical questions, ranging from discovering “killer” asteroids, exploring the time domain universe, mapping the evolution and structure of our Milky Way galaxy, to examining the nature of dark matter and dark energy. The project includes an 8-meter class wide field telescope, a 3.2 gigapixel camera with 2-second readout, and a state-of-the-art peta-scale data management system to process, archive, and distribute the 15 TB of data produced every night. Rubin Observatory Construction started an 8-year effort in July 2014. Rubin Observatory Construction is a single project funded by both the National Science Foundation and Department of Energy. Once completed, the Rubin Observatory will conduct the Legacy Survey of Space and Time (LSST) which will be the largest and most modern optical survey project ever built and a flagship of US science and engineering.
The System Integration, Test & Commissioning (SIT-Com) team is responsible for leading and coordinating the final system integration and commissioning of the Rubin Observatory System. The SIT-Com team also includes the Project Systems Engineering group (PSE). The PSE is responsible in delivering a commissioned system that meets all stakeholders’ needs. At this stage of the project, this means ensuring that all of the requirements are properly verified and validated. This includes developing and managing requirements, verification plans, verification test specifications, performance estimates and cross-subsystem interfaces. Many of these functions are managed by the PSE using Model Based Systems Engineering (MBSE). As a whole, the SIT-Com team is responsible for conducting verification activities, tracking progress, and working with other project members developing responses to issues and non-compliances that are discovered.
Rubin Observatory is soliciting applicants for a Commissioning-Verification Scientist within the SIT-Com team, this position will based either out of the Rubin Observatory Project Office (Headquarters) in Tucson, AZ or La Serena, Chile (with the later preferred). The Commissioning-Verification Scientist will play a key role during the Projects System Integration, Test and Commissioning phase with extensive duties on the summit site in Chile.
The successful candidate will assist in the development and execution of verification plans as well as general commissioning activities to demonstrate the Rubin Observatory System has met its design requirements and specifications.
With the project now at the beginning of its commissioning phase, the Commissioning-Verification Scientist will work closely with Project systems engineers to continue the development of these verification plans, test cases, test specifications, procedures in the form of executable code. During conduct of commissioning activities, the Commissioning-Verification Scientist is expected to perform detailed technical and science based analysis of test results.
This is a “once-in-a-career” opportunity to be part of the team that ushers in a new world-class National astronomical facility that will change the way we see the universe. The position being sought runs through the completion of the Rubin Observatory Construction Project (c. late 2022) with multiple opportunities for continued engagement during the Rubin Observatory’s operational phase.
The Commissioning-Verification Scientist is expected to use the Project’s developed common Work Management Systems (e.g. JIRA) for coordinating work during the commissioning phase of the Project, including the development and execution of verification activities and recording of verification analyses and results with the Project’s JIRA based framework.
The Systems Commissioning-Verification Scientist will report to the Systems Scientist/Commissioning Manager.
