Senior Site Reliability Engineer

Join ServiceTitan as a Senior Site Reliability Engineer. In this role, you will be responsible for the reliability and health of our cloud-based applications, designing signals to detect issues and building systems to improve performance as we scale. You will participate in an on-call rotation, design and maintain observability dashboards, operate and improve our Kubernetes-based compute platform, and collaborate with product engineering teams. This position offers flexible time off, fully paid medical, dental, and vision coverage, and various other benefits.

• Participate in an on-call rotation, using runbooks and playbooks to diagnose and resolve production issues.
• Design, build, and maintain observability dashboards and alerting grounded in Service Level Indicators (SLIs) and Service Level Objectives (SLOs).
• Operate and improve our Kubernetes-based compute platform, which runs the large majority of our infrastructure.
• SRE principles: practical experience with SLIs, SLOs, and error budgets — able to speak to how you've defined and monitored these on real systems, not just definitions
• Kubernetes (must-have): strong, hands-on understanding of Kubernetes as a system
• Cloud engineering & networking: solid grounding in AWS or Azure, including networking fundamentals (subnetting, IP addressing)
• 8-10+ years of relevant hands-on experience
• Strong programming skills with the ability to build web applications — ideally with solid working knowledge of .NET and <ASP.NET>. We're also open to strong Python (Flask, FastAPI) or Java (Spring) backgrounds. The coding assessment will be tailored to whichever language/framework you're most comfortable in
• Observability: deep experience with at least one modern observability stack (OpenTelemetry, Prometheus, Grafana, Datadog, or Elasticsearch) and the ability to translate that understanding across tools
• Strong production troubleshooting skills — comfortable diagnosing issues under pressure
• CI/CD: strong understanding of a CI/CD system — GitHub Actions preferred, but TeamCity, Azure DevOps, or GitLab CI experience is acceptable
• Experience with distributed systems and their common failure modes (retries, timeouts, cascading failures)
• Nice-to-have: database experience (not mandatory — databases are monitored by the same team, not owned individually)
• You're comfortable guiding and making decisions with limited information, and capable of operating within the trade-offs between solving for immediate needs versus bigger-scale solutions
• You feel rewarded by developing an operability culture in a quickly growing and changing environment, and you're comfortable owning a wide and diverse set of problem areas
• You're someone who enjoys being directly accountable for the reliability of a business-critical, large-scale enterprise system
• Being human isn’t about checking every box on a list. It’s about the experiences we have, people we meet, and the perspectives we share. So, if you have the skills but are hesitant to apply because of your background, apply anyway
