This includes optimizing existing metrics collection and alerting systems to ensure proactive monitoring and rapid issue resolution. Furthermore, you will play a crucial role in contributing to our internal documentation and knowledge base, sharing your expertise and insights with the wider engineering team.
• This role requires extensive experience with the Linux kernel, particularly in optimizing the networking stack and storage protocol performance on the client side. You will also be involved in the design and performance analysis of storage system architectures, with a strong emphasis on Ceph. This is a unique opportunity to join a fast-growing team and make a lasting impact on Vultr and the future of cloud infrastructure.
• Key responsibilities include:
• Driving improvements in Vultr's cloud storage performance from a customer-centric viewpoint.
• Performing rigorous benchmarking and analysis of storage performance across diverse product combinations, including storage, GPU, and compute.
• Analyzing benchmark results and recommending specific tuning strategies to enhance storage performance.
• Continuously improving the stability, scalability, functionality, performance, and cost-efficiency of the Ceph-based Cloud Storage System.
• Actively contributing to the design and architectural decisions for Ceph-based Cloud Storage.
• Developing and enhancing automation frameworks for the Ceph-based Cloud Storage infrastructure.
• Optimizing existing metrics collection and alerting systems for proactive monitoring.
