Staff Software Engineer, Stateful Fleet Management
Aarhus, Denmark · Central Denmark Region, Denmark
Posted on Friday, March 31, 2023
About The RoleWe build Uber’s infrastructure to deploy and run all database engines and other stateful systems globally. Our mission at Uber is to run all storage solutions at scale, with high availability, low cost, and a high level of automation. All changes are automated (or self-healing) such as doing kernel upgrades, handling host failures, or expanding storage clusters. About UsWe run around 100,000 hosts, millions of containers, and exabytes of storage across multiple geographical regions with availability zones in both Uber’s own data centers and multiple cloud vendors. Databases are containerized and co-located on hosts with intelligent placement to optimize utilization and failure domain anti-affinity to improve efficiency and consistency. Services are written in Go and All code changes are peer-reviewed.We have vast opportunities ahead to extend the integrations with the different DBMS and to increase fleet-wide efficiency and reliability by optimizing scheduling, auto-scaling, and host local configurations such as CPU-sets, Numa and LVM. We strive to automate all operations that are currently handled by on-call engineers with the end goal of having a fully self-healing system - without compromising on availability or reliability.Our team consists of a healthy combination of both junior and senior engineers with a broad range of experiences across the industry. We value ideas over hierarchy, getting things done, and having a measurable impact on the business. We work closely with our customer teams in San Francisco, Palo Alto, Seattle, New York, and Vilnius. 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.
