We're unstoppable when driven individuals come together to solve bold challenges, inspire innovation, and create platforms that power the future.
- This role ensures the reliability and resilience of digital infrastructure, enabling efficient software development and deployment. It focuses on automating processes and reducing manual effort to prevent operational incidents, improve system performance, and enhance overall operational efficiency.
- As part of the Enterprise Procurement Engineering organization, this role supports a large-scale enterprise device management, procurement, and application delivery ecosystem that enables critical operations.
- The Sr Site Reliability Engineer leverages automation, CI/CD practices, scripting, observability, and incident management expertise to improve reliability, scalability, and operational efficiency across a complex, cloud-native technology environment. This work directly impacts organizational stability and customer experience by ensuring the availability, performance, and reliability of critical systems.
Key Responsibilities:
- Automate processes to accelerate software development and deployment while minimizing manual interventions — including CI/CD pipelines on Azure DevOps or GitLab, deployment automation, and endpoint management workflows.
- Design, build, and enhance automation solutions on Azure that improve operational efficiency, deployment consistency, and service reliability across complex enterprise environments.
- Manage and scale Kubernetes-based workloads; own cluster reliability, resource optimization, deployment strategies, and container orchestration practices.
- Enhance system reliability and resilience by identifying issues and implementing preventive measures to reduce downtime and improve operational stability.
- Conduct root cause analysis and collaborate with problem management teams to prevent incident recurrence and continuously improve system operations.
- Leverage Python, Bash, and related scripting/programming tools to improve system robustness, deployment quality, and operational efficiency.
- Implement and maintain observability solutions — metrics, dashboards, alerting, and distributed tracing — using Splunk, Grafana, Prometheus, or equivalent platforms to drive proactive incident detection.
- Implement and support secure automation practices, including secrets management, credential lifecycle automation, and integration with approved enterprise security platforms (e.g., CyberArk, HashiCorp Vault).
- Partner with product, engineering, cybersecurity, and operations teams to design and implement scalable deployment and automation solutions.
- Support modernization initiatives involving mobile device management platforms, application deployment automation, platform migrations, and operational process improvements.
- Continuously learn new skills and technologies to adapt to changing environments and drive innovation.
- Perform other duties and projects as assigned.
