As a Senior Site Reliability Engineer on the Site Experience SRE team, you will operate at the critical intersection of infrastructure, product engineering, and user experience. You will lead reliability engineering initiatives for high-traffic, business-critical surfaces—including user-facing APIs, content delivery, feed generation, search infrastructure, media streaming, and real-time messaging engines. Partnering closely with product and core infrastructure teams, you will architect systems for high availability, eliminate operational risk, drive SLIs/SLOs, and build developer automation to ensure every user interaction across web and mobile is fast, resilient, and reliable.
Key Responsibilities
Reliability Leadership & Infrastructure Architecture
- User Experience Reliability: Lead end-to-end reliability, latency reduction, and performance initiatives for user-facing surfaces across APIs, content delivery networks, feed generation, search, and real-time systems.
- Architect for Internet Scale: Partner with product and platform engineers to design redundant, fault-tolerant distributed architectures capable of handling massive global traffic spikes with graceful degradation and traffic management guardrails.
- Systemic Risk Mitigation: Audit complex multi-service dependency trees, deployments, and infrastructure components to identify single points of failure, establishing proactive mitigation strategies that prevent high-severity incidents.
Automation, Observability & Engineering Standards
- Automated Solutions & Tooling: Eliminate manual operational tasks by building automated tooling for deployment safety, self-healing incident remediation, and continuous reliability guardrails.
- SLOs & Operational Excellence: Define and champion company-wide SRE best practices around Service Level Indicators (SLIs), Service Level Objectives (SLOs), capacity planning, and release engineering maturity.
- Mentorship & Technical Influence: Provide technical mentorship to engineers across SRE and software engineering teams, elevating the operational excellence bar and reliability culture across Reddit.
Requirements
Distributed Systems & SRE Mastery
- Experience Track: 5+ years of professional experience in Site Reliability Engineering, Infrastructure Engineering, or related roles operating large-scale distributed production environments.
- High-Traffic Production Background: Proven track record of supporting high-throughput, user-facing internet systems.
- Core Engineering Foundations: Deep operational understanding of at least one core domain: distributed systems architecture, Linux internals, network protocols, or cloud-native environments.
- Programming Proficiency: Strong software development skills in languages such as Go, Python, or similar modern languages.
- Observability Mastery: Deep experience with metrics, structured logging, distributed tracing, and automated alerting frameworks.
- Troubleshooting & Optimization: Demonstrated capability to debug complex, multi-layered failures across application code, cloud infrastructure, networking layers, and microservices.
- SRE Frameworks: Proven success implementing SLOs, operational automation, incident management workflows, and performance tuning.
Preferred Qualifications
- Experience operating containerized workloads at scale using Kubernetes, containers, and modern CI/CD deployment platforms.
- Practical experience with modern telemetry and distributed data infrastructure stacks (e.g., Prometheus, Grafana, OpenTelemetry, Envoy, Kafka, ClickHouse, Cassandra, Redis).
- Background in CDN edge optimization, global traffic engineering, and multi-region cloud deployment architecture.
- Demonstrated experience leading large-scale incident response post-mortems or engineering operational transformations.
- Active open-source software contributions or participation in technical SRE communities.
Total Rewards & Benefits
- Compensation & Equity: US Remote base salary range ($190,800 – $267,100 USD) + competitive Restricted Stock Unit (RSU) equity grants + potential commission eligibility.
- Healthcare & Wellbeing: Comprehensive health, dental, and vision insurance packages; income replacement programs; mental health coaching benefits; and gender-affirming care coverage.
- Retirement & Financial: 401(k) retirement savings plan with generous employer matching.
- Family Planning & Support: Comprehensive family planning support, generous paid parental leave, and caregiving assistance programs.
- Workplace & Lifestyle: Fully remote flexible-first work environment, home office/workspace stipends, professional development allowances, flexible PTO, and paid volunteer time off.
