Your key responsibilities

Design and implement reliability architecture and engineering standards for scalable, resilient and operationally efficient services, platforms and infrastructure.

Build and evolve enterprise-grade observability capabilities across metrics, logs and traces, including service-level objectives and service-level indicators, to provide actionable insights into system health and customer experience.

Implement and continuously improve site reliability engineering practices, including error budgets, capacity modeling, resilience testing, graceful degradation and operational readiness.

Architect automation and self-service capabilities, and design secure continuous integration and continuous delivery pipelines, deployment automation, quality gates and rollback strategies.

Troubleshoot complex production issues, perform deep root-cause analysis and collaborate across engineering, platform and infrastructure teams to deliver long-term reliability improvements.

What you bring

Required qualifications

Deep software engineering expertise designing, building and operating large-scale, distributed, application programming interface-driven systems in production.

Strong continuous integration and continuous delivery experience with tools such as Azure DevOps, GitHub Actions, Jenkins or Harness, including pipeline design, deployment automation and release engineering.

Expertise in observability, alerting and reliability engineering using technologies such as Prometheus, Grafana, Datadog, Splunk or the Elastic Stack.

Strong cloud experience with Amazon Web Services, Microsoft Azure or Google Cloud Platform, including infrastructure as code, platform automation and cloud-native design patterns.

Hands-on experience with Linux, including Red Hat Enterprise Linux, Windows, SQL Server or Oracle databases, and complex enterprise technology environments, combined with experience operating highly available, mission-critical platforms.

Preferred qualifications

Strong automation and scripting skills using Python, Bash, Ansible, PowerShell or similar technologies; C and .NET experience is an additional advantage.
