Staff Engineer, Site Reliability Engineer

OnStar is a cornerstone of General Motors’ connected services—bringing safety, security, diagnostics, navigation, and convenience to customers through the mobile apps, website, and the in-vehicle experience, supported by a complex set of cloud services and integrations operating at global scale. To support this, we’re scaling our Site Reliability Engineering (SRE) organization in Dublin, responsible for keeping the OnStar product line resilient, performant, and scalable for millions of customers. 

We are seeking an experienced technical leader with a deep background in SRE, cloud operations, and project ownership to help define, build, and evolve reliability practices across our customer-facing OnStar experiences and the services behind them. 

What You’ll Be Doing 

• Lead the design and implementation of scalable, fault-tolerant, and observable infrastructure supporting OnStar mobile and web experiences, in-vehicle services, and the backend platforms and integrations that power them. 

• Champion configuration management, infrastructure refactoring, and testing frameworks to strengthen system resilience. 

• Partner across SRE, development, and product teams to improve service reliability, deployment safety, and incident response practices. 

• Drive internal consultation and strategic planning on reliability standards for new OnStar capabilities, customer-facing releases, and platform initiatives. 

• Define and evolve observability strategy using tools such as Prometheus, Grafana, and Datadog, with automated alerting and actionable SLO dashboards. 

• Own and improve on-call practices, manage blameless postmortems, and guide root cause analysis to eliminate recurring failures. 

• Mentor engineers and help shape a high-performance culture rooted in extreme ownership and operational excellence. 

• Support compliance and privacy-driven engineering initiatives across connected services, with potential crossover into areas like data retention and safety certification tooling. 

What You Bring 

• 8+ years in SRE, DevOps, or systems engineering, including experience managing or mentoring high-impact teams. 

• Track record of building and maintaining high-scale, cloud-native systems (preferably AWS, GCP, or Azure). 

• Expertise in container orchestration and deployment strategies using Kubernetes and CI/CD pipelines. 

• Proficiency in Python, Go, or Java, with strong code review and readability standards. 

• Experience leading cross-functional infrastructure projects, configuration strategy, or organizational tooling initiatives. 

• Ability to think and act under pressure — whether debugging a live incident or balancing uptime vs cost trade-offs. 

• Familiarity with privacy engineering, data security, or experience supporting compliance frameworks is a plus. 

• Strong communication skills — able to influence, mentor, and lead across diverse technical teams.
