Sr Software Engineer, Fleet Reliability and Performance
Central Denmark Region, Denmark
Posted on Friday, March 31, 2023
About The RoleWe build the foundation for all of Uber’s fleet of 100,000s of hosts or VMs by ensuring they are running optimally and are configured efficiently for the container platforms using the hosts. We observe and detect a broad range of reliability and quality problems through codified processes and automatically drive remediation.We run generically across bare metal hosts and VMs and across our own on-prem data centers and multiple cloud vendors, and closely collaborate to develop integrations that ensure effective and automated management.Internally we integrate with Uber’s stateful and stateless container scheduling platforms to run host operations in a safe and efficient way and use this to realize remediation of bad hosts or apply fleet-wide upgrades such as rolling out a new kernel.We maintain the base OS image and handle kernel upgrades and configuration and provide high-fidelity host and container metrics to ensure secure and optimal performance for the workloads on the hosts.Our team consists of a healthy combination of both junior and senior engineers with an array of experiences across the industry. We value ideas over hierarchy, always improving, getting things done through code, and having a measurable impact on the business. What You Will DoYou will improve your software engineering, systems engineering, hardware/Linux OS/kernel knowledge, cloud knowledge, and infrastructure systems experience to investigate and decipher ambiguous problems in our production fleet while also contributing to planning, new systems design, and improvement of existing systems to enable even greater efficiency and insight.
