We're looking for a Senior Observability Engineer to lead the development and scaling of telemetry systems that keep our platforms reliable, performant, and resilient. You'll play a critical role in shaping observability practices across engineering and infrastructure teams , enabling better incident response, deeper system insight, and stronger delivery outcomes. You will define how we measure, detect, and respond to what matters , empowering teams to build and operate services with confidence. As a senior contributor, you will own key initiatives, drive adoption of observability standards, and collaborate across the company to enable scalable, efficient engineering.

Responsibilities

• Lead the architecture, delivery, and continuous improvement of observability solutions , leveraging tools like Splunk Observability Cloud, Google Cloud Observability or equivalent platforms.
• Build scalable, automated telemetry pipelines using Terraform and modern Infrastructure-as-Code (IaC) workflows to support auditability, reliability, and self-service adoption.
• Define and evolve best practices for metrics, traces, logs, and events to ensure high-signal alerting and consistent, actionable instrumentation across our systems.
• Collaborate with application, platform, security, and compliance teams to integrate observability into every phase of the development lifecycle, from instrumentation patterns to SLOs to post-incident reviews.
• Drive the definition and adoption of internal standards for service-level indicators (SLIs), error budgets, and system health across services.
• Lead adoption of modern AI-assisted development and debugging workflows within observability tooling and automation, helping teams accelerate incident response, system instrumentation, and root cause analysis.
• Identify and resolve cross-functional observability challenges through simplification, standardisation, and durable solution design.
• Participate in SRE/Platform on-call rotations to stay connected to production challenges and continuously improve observability tooling, alert design, and incident response.
• Provide technical guidance to engineers across teams, helping them apply telemetry principles to improve system insight.
• Champion a culture of reliability through enablement , building reusable frameworks, shared documentation, and team-level training that improves observability without increasing toil.
• About You:
• 5+ years of experience in SRE, DevOps, or platform engineering roles, with a deep specialisation in observability systems and telemetry design.
• Recognised as a subject-matter expert in observability tools and practices, especially in cloud-native, distributed systems environments.
• Proven track record of delivering high-impact technical projects that improve system visibility, reduce operational risk, or enhance incident response at scale.
• Deep knowledge of metrics, logs, traces, and events , and how to apply them to both product services and infrastructure components.
• Hands-on experience managing telemetry pipelines with Terraform , CI/CD tooling, and service instrumentation in Kubernetes-based environments.
• Strong understanding of system-level design princip
