In addition to supporting the HPC cluster in Phoenix, the Engineer will also contribute to other infrastructure and customer initiatives as business needs arise. The Engineer will be required to shift priorities, support parallel efforts, and provide technical expertise across multiple projects, including deployments, upgrades, troubleshooting, and documentation. Additional assignments may include short-term tasking in adjacent programs, collaboration with cross-functional engineering teams, and participation in planned maintenance windows or special projects to meet organizational commitments. Travel to different customer sites is expected to be a maximum of 25% of the time. US citizenship is a mandatory requirement for this position.
