Staff Software Engineer, Compute Reliability and Efficiency

The Compute Reliability and Efficiency team is looking to hire a Staff Software Engineer with a focus on lower-level (Linux and Kubernetes) systems engineering that thrives at the intersection of infrastructure and software engineering. 

At Reddit, our Compute organization breaks down into 2 teams:

• Compute Reliability and Efficiency (CRE)
• Compute Platform and Orchestration (CPO)

CRE: Intra-cluster engineering problems focused on balancing performance, efficiency, and stability. With a focus on creating durable software solutions to automate operation of Reddit’s compute clusters. A subset of focus areas include:

• Detection of node-level (Linux) 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.
• Lower-level Kubernetes integrations such as CSI drivers, node probs, and kernel-level observability.
• Cluster upgrades, both mechanical process concerns and automation.

CPO: Higher-level orchestration of both compute capacity and workload primitives to support our multi-cloud, multi-region, deployments. A subset of current focuses include:

• 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.

As a member of the Compute Reliability and Efficiency team, you’ll be solving some of the world’s largest at-scale infrastructure problems using software we create along with integrating services from the cloud native ecosystem. Your work will directly impact hundreds of millions of users around the world. Join us and help build the future of Reddit!

In your day-to-day, you can expect to:

• Work collaboratively with a team of software engineers to create and maintain the foundational platform for running Reddit’s infrastructure.
• Execute performance and reliability analysis on our Linux-based Kubernetes fleet.
• Design, write (Golang), and deliver software to improve the availability, scalability, latency, and efficiency of Reddit’s Compute Platform.
• Contribute feedback to the technical and strategic direction of the compute platform.
• Automate critical aspects of the development process such as service creation and management, as well as critical infrastructure operations.
• Share on-call responsibilities with the Compute team. 

You have:

• 7+ years of experience working in the infrastructure domain – with a focus on lower-level systems such as Linux.
• Language proficiency in either Go (Preferred), Rust, or Python.
• Understanding of kernel primitives (cgroups, namespaces), cpu scheduling, userspace concerns, and packet processing.
• Experience developing on top of Kubernetes or similar distributed systems.
• Strong troubleshooting competency ranging from higher-level orchestration concerns to lower-level runtime ones.
• Experience designing large systems, scoping work, and building consensus with other engineers.
• Excellent communication skills to collaborate with a service-oriented team and company.

Benefits:

• Comprehensive Healthcare Benefits
• 401k Matching
• Workspace benefits for your home office
• Personal & Professional development funds
• Family Planning Support
• Flexible Vacation (please use them!) & Reddit Global Wellness Days
• 4+ months paid Parental Leave
• Paid Volunteer time off
