Role

What you'll do.

Join Xero's central Observability team as a Senior Site Reliability Engineer, where you'll architect standardized observability systems and telemetry frameworks that empower product teams to adopt agentic-first development practices. This senior-level position focuses on implementing OpenTelemetry standards, designing intelligent alerting systems, and optimizing platform reliability across distributed cloud infrastructure serving millions of small businesses globally. You'll collaborate across Australia and New Zealand with high autonomy while influencing how the entire engineering organization operates reliably under scale.

Responsibilities

  • Architect Standardized Observability Systems: Design and implement vendor-agnostic telemetry frameworks and data pipelines that enable standardized observability across Xero's distributed applications. Establish consistent logging, metrics, and distributed tracing standards that support intelligent operational workflows and agentic development practices.
  • Drive OpenTelemetry Implementation: Lead the adoption and implementation of OpenTelemetry standards across distributed systems, ensuring consistent instrumentation practices that reduce vendor lock-in and enable seamless data portability across observability platforms.
  • Optimize Platform Efficiency and Cost: Analyze and optimize cloud infrastructure costs and system performance across large-scale environments. Monitor resource utilization, identify inefficiencies, and implement cost-reduction strategies while maintaining or improving system reliability and performance metrics.
  • Design Automated Alerting and Reliability Scorecards: Build intelligent alerting systems and reliability scorecards that streamline incident investigation, reduce mean-time-to-resolution, and provide clear visibility into system health across product teams. Implement automation that minimizes alert fatigue while maintaining critical incident visibility.
  • Support Cross-Functional Product Teams: Collaborate with product engineering squads to establish shared reliability benchmarks, provide platform standards guidance, and lift observability maturity across the organization. Mentor engineers on best practices for instrumenting applications and interpreting telemetry data.
  • Set Technical Direction for Reliability Infrastructure: Contribute to architectural decisions that shape how reliability and observability capabilities are delivered across Xero's product landscape. Influence engineering culture toward proactive, data-driven reliability practices and automated incident response workflows.
