We are looking for an experienced Observability / Reliability Engineer leading our monitoring, logging and observability strategy and implementation across various projects. You will design, implement, scalable observability solutions that provide meaningful insights into system performance, enhance operational resilience, and improve user experience. Partnering with engineering, operations, and product teams, as well as external teams, you will drive data-driven improvements that promote effectiveness, efficiency and improve user experience, while reducing manual work and enabling faster incident response in our complex and regulated environment.

You will treat observability as a product: designing, owning, and continuously improving observability capabilities that support performance-oriented culture.

Responsibilities

• Lead observability practices across services, infrastructure, and applications, ensuring actionable visibility into user impacting conditions, system health, and system performance.
• Partner with NOC, system administration, and development teams to translate operational challenges into practical observability and automation solutions.
• Build and optimize the observability platform, managing it as a product with roadmap planning and stakeholder engagement.
• Design service-level monitoring (e.g., SLIs, SLOs, synthetic checks, meaningful alert thresholds) to improve early detection of service degradation and outages.
• Develop, maintain, and refine dashboards, telemetry pipelines, and log analysis capabilities that support effective and efficient troubleshooting, incident response, and performance optimisation.
• Identify visibility gaps impacting operational effectiveness and implement telemetry enhancements to close those gaps.
• Improve alert signal quality by reducing noise through deduplication, suppression strategies, maintenance window awareness, and better severity mapping.
• Contribute to automation initiatives that reduce repetitive operational work and support safe and consistent remediation action.
• Enable teams through training, documentation, and best practices to leverage observability tools and telemetry insights.
• Contribute to service management processes including incident and problem management, and blameless postmortems.

• 7+ years of experience in observability engineering, SRE, infrastructure monitoring, or related reliability-focused roles with hands-on implementation exposure.
• Strong understanding of observability fundamentals, including metrics, logs, traces, telemetry correlation, and performance analysis.
• Experience with modern observability tools and stacks such as Prometheus, Grafana, OpenTelemetry, Elastic Stack, Datadog, Splunk, New Relic, or equivalent platforms.
• Practical experience improving alert quality, monitoring strategy, or service visibility in production environments.
• Familiarity with service reliability concepts including service journeys, SLIs, SLOs, alert thresholds, and incident detection approaches.
• Strong systems thinking and troubleshooting skills, with the ability to translate operational problems into scalable technical solutions.
• Collaborative approach with clear communications across technical and non-technical stakeholders.
• Experience working with external vendors or cross-functional teams

Nice to Have

• Background in infrastructure engineering, platform operations, or distributed systems environments.
• Experience with incident and problem management, enterprise automation, regulated environments.
• Knowledge of synthetic monitoring, capacity management or resilience engineering.
