Senior Lead SRE - Platform Standards, Observability & Production Readiness

Job summary

The Senior Lead Site Reliability Engineer establishes and enforces reliability and observability standards across a broad application estate, guiding engineering teams through production-readiness requirements. The role runs end-to-end observability assessments, maps customer journeys to alerts and service level indicators and objectives, validates metrics queries, and conducts failure-mode analyses and chaos gamedays. It also supports estate-scale reliability practices and tooling using technologies such as PromQL, Dynatrace, Prometheus, Cortex, and Grafana.

Qualifications

• Formal training or certification in site reliability engineering concepts with advanced applied experience.
• Advanced understanding of site reliability principles and demonstrated implementation experience.
• Advanced experience with white-box and black-box monitoring, service level objectives, alerting, and telemetry collection.
• Daily hands-on experience writing and debugging PromQL or equivalent time-series metrics queries.
• Experience defining customer-focused service level indicators and objectives from user journeys.
• Experience using authorized AI capabilities in reliability workflows, validating outputs, and handling sensitive data appropriately.
• Ability to establish safe AI practices for operations while maintaining resiliency, security, and auditability.
• Deep knowledge of software applications and technical processes in one or more disciplines.
• Strong communication, mentoring, and relationship-building skills, including presenting evidence-based findings that may be unwelcome.
• Preferred experience with failure analysis, chaos experiments, error budgets, recovery governance, or influencing teams without direct authority.

Responsibilities

• Develop designs, roadmaps, and programme charters with engineering teams.
• Lead observability assessments covering user journeys, alert coverage, journey-level indicators and objectives, and failure modes and effects analysis.
• Design and run chaos gamedays to test identified failure modes and alert detection.
• Assess applications against production-readiness requirements and enforce production gates.
• Mentor technologists and champion adoption of site reliability engineering practices.
• Develop robust observability and reliability designs that avoid unnecessary toil and technical debt.
• Validate that metrics and indicators can report breaches by querying the metrics store.
• Use authorized AI capabilities to support reliability design, operational decisions, and estate-scale screening while validating outputs.
• Drive improvement and debugging of critical components by analyzing application and platform dependencies.
• Contribute to reliability assessments, production-readiness reviews, service level objective analysis, alerting standards, recovery evidence, and internal tools.
