Job SummaryWe are seeking a DevOps Engineer with experience managing large-scale, on-premises infrastructure deployments, to work on the DSA-2000 project, a world-leading radio telescope that will commence construction in 2026. The array will use 2000, 5-meter dishes to observe at radio wavelengths (0.7 - 2 GHz frequency range) to survey the skies 10x faster than any radio telescope current or planned. The telescope will conduct a broad range of research, including the study of the formation of galaxies, the search for cosmic explosions, and investigations into the nature of gravity.
The applicant would fulfill the role of DevOps Engineer for the DSA-2000 project. This role will support the Software Group as we progress through the final design stage to construction.
The role can be based at either the Caltech campus, the Owens Valley Radio Observatory in Big Pine, CA, or hybrid/remote.
Essential Job DutiesThe candidate will work closely with the rest of the DSA-2000 team and support the following main duties:
- On-Premises Infrastructure Management: Support the design, deployment, and management of the on-premises infrastructure for the DSA-2000's processing and monitoring pipelines. This will involve assisting with the provisioning and configuring of thousands of servers with high-performance computing capabilities (including approximately 4,000 Nvidia RTX 4000 Ada GPUs and over 30,000 CPU cores) hosted at the project data center in Nevada where the telescope is located.
- Automation: Help in developing and implementing automated processes for server provisioning, configuration management, and testing. This will utilize tools like Ansible, Puppet, Chef, or similar configuration management solutions.
- Containerization and Orchestration: Assist in implementing containerization strategies using Docker and support the orchestration of container deployments using Kubernetes or similar container orchestration platforms.
- CI/CD Pipelines: Contribute to the design and implementation of robust CI/CD pipelines for the DSA-2000 software to ensure continuous integration and delivery.
- Monitoring and Logging: Help establish comprehensive monitoring and logging systems to track infrastructure health and application performance.
- Security and Compliance: Support efforts to ensure compliance with relevant security standards and regulations.
- Collaboration: Collaborate closely with the Software Development team to understand their needs and provide ongoing support.
