Lead Site Reliability Engineer

As a Lead Site Reliability Engineer, you'll set the reliability standard across our Infrastructure Engineering organisation. You'll define how we measure reliability for critical services, partnering with engineering teams to build and refine Service Level Objectives that connect infrastructure performance to the experiences our platforms support. You'll turn complex telemetry into clear, actionable insights that help teams and senior leaders make better decisions about reliability, risk, and priorities.

• Lead and mature the Service Level Objective development process across Infrastructure Engineering, establishing clear frameworks and standards for setting meaningful reliability targets.
• Partner with engineering teams to design and implement Service Level Objectives, beginning with the critical user journeys each service supports and translating them into measurable indicators, targets, and error budget policies.
• Review and refine existing reliability objectives to keep them aligned with changing customer impact, technical dependencies, and business priorities.
• Connect infrastructure reliability targets to the application and platform experiences they support, making dependencies and their impact on end-user experience clear and measurable.
• Build reporting processes and tooling that provide a clear view of reliability across critical components, translating technical signals into actionable insights for Senior Managers and Directors.
• Influence reliability practices across teams through technical guidance, design reviews, mentoring, and collaboration with engineering partners.
• Help teams distinguish meaningful service degradation from true downtime by applying thoughtful measurement strategies to complex distributed systems.

• A Bachelor's Degree in Computer Science or a related field, or equivalent relevant education, experience, and training.
• At least 7 years of experience in Site Reliability Engineering, including hands-on experience defining and operationalizing Service Level Objectives, Service Level Indicators, and error budgets at scale.
• Deep experience with observability platforms such as Datadog, including building dashboards, monitors, and reporting from metrics and logging pipelines.
• Experience connecting infrastructure-level reliability objectives to application or platform-level outcomes and evaluating how technical dependencies affect end-user experience.
• Strong knowledge of distributed systems and the failure modes that can make reliability measurement complex, with the ability to assess what technical signals truly represent.
• Proven ability to influence across engineering teams, translate reliability concepts for technical and non-technical audiences, and drive alignment without direct authority.
• Excellent written and verbal communication skills, including experience developing and presenting reliability reporting to Senior Managers, Directors, and cross-functional stakeholders.
• Working knowledge of cloud and infrastructure environments such as Amazon Web Services, Kubernetes, and on-premise systems, with the technical depth to partner effectively with the teams operating them.

• Bonus, equity, and benefits as applicable
