Position Overview

The Compute team is looking to hire a Senior Software Engineer that thrives at the intersection of infrastructure and software development. This team’s challenges break into 2 domains: Platform Engineering and Cluster Engineering.

Platform Engineering Focus Areas:

• Software automation that creates, manages, and destroys clusters in our fleet.
• APIs and controllers that support multi-cluster deployment and scheduling mechanics.
• Core SDKs that enable controller development in the larger organization.
• Software that codifies out-of-cluster ancillary concerns such as network configurations and managed services.

Cluster Engineering Focus Areas:

• Detection of node-level performance characteristics and making availability decisions based on the data.
• Schedulers that support more efficient packing of resources along with reactive rescheduling on the basis of changing compute availability.
• Kubernetes controllers that offer APIs in the cluster and perform reconciliation to reach a desired state.
• Cluster upgrades, both mechanical process concerns and automation.

As a member of the Compute team, your work will span these 2 domains, which are rich with challenging infrastructure and software engineering problems. Your work will directly impact hundreds of millions of users around the world. Join us and help build the future of Reddit!
