Staff Site Reliability Engineer, Site Experience

Reddit is a community of communities, built on shared interests, passion, and trust. As Reddit scales globally, reliability and performance are paramount. The Site Experience SRE team operates at the intersection of infrastructure, product engineering, and user experience, ensuring fast, reliable, and resilient interactions across all platforms.

What you’ll do:

• Lead Reliability Engineering for User Experience: Drive reliability, scalability, and operational excellence for critical user-facing systems and services. Improve performance and resiliency across APIs, content delivery, feed generation, search, messaging, and real-time experiences.
• Architect for Scale: Partner with product and infrastructure engineering teams to design highly available and performant systems under massive global load. Guide architectural decisions regarding failover, redundancy, graceful degradation, traffic management, and capacity planning.
• Reduce Operational Risk: Identify systemic risks and reliability bottlenecks across services, dependencies, deployments, and infrastructure. Build proactive mitigation strategies and drive engineering improvements to reduce incidents and enhance service health.
• Drive Automation: Eliminate repetitive operational work through automation and tooling. Build systems that improve deployment safety, incident response, remediation workflows, and reliability guardrails.
• Incident Management: Lead complex incident response efforts across engineering teams. Drive blameless postmortems, identify root causes, and ensure sustainable long-term fixes.
• Influence Engineering Standards: Define and champion best practices for reliability engineering, SLIs/SLOs, capacity management, release engineering, and operational maturity across the company.
• Mentor and Multiply Impact: Provide technical leadership and mentorship to engineers across SRE and software engineering teams, shaping reliability culture and raising operational excellence standards.

What We’re Looking For

• 8+ years of experience in Site Reliability Engineering, Infrastructure Engineering, or related roles operating large-scale distributed systems.
• Strong collaboration and communication skills with the ability to influence technical direction across teams.
• Extensive experience supporting high-traffic, user-facing production environments.
• Deep understanding of one or more: distributed systems, networking, Linux systems, cloud-native architectures.
• Experience designing highly available systems with robust operational and reliability practices.
• Strong programming skills in languages such as Go, Python, or similar.
• Strong understanding of observability systems, including metrics, logging, tracing, and alerting.
• Experience improving reliability through SLOs, automation, incident management, and performance optimization.
• Demonstrated ability to troubleshoot complex issues across applications, infrastructure, networking, and services.

Nice to Have

• Experience operating systems at internet-scale traffic volumes.
• Experience with Kubernetes, containers, cloud infrastructure, and modern deployment platforms.
• Familiarity with technologies such as Prometheus, Grafana, OpenTelemetry, Envoy, Kafka, ClickHouse, Cassandra, Redis, or similar distributed infrastructure technologies.
• Experience with CDN optimization, edge reliability, traffic engineering, or global infrastructure.
• Contributions to open-source software or participation in technical communities.
• Experience leading large-scale incident response and operational transformation initiatives.
