• Design and implement deployment architectures for foundational services, ensuring high availability, fault tolerance, and disaster recovery across regions.
• Develop and enforce SLOs for managed services; lead incident response, root cause analysis, and post-mortem reviews to drive continuous reliability improvements.
• Collaborate with network, security, and application teams to ensure foundational services meet the evolving demands of global business growth.
• Identify automation opportunities across host management and service operations; drive tooling and process improvements to reduce toil and increase operational efficiency.

• Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, Computer Science or related majors.

• Proficiency with DevOps tooling, including configuration management tools (e.g., Ansible, Salt, Puppet) and CI/CD pipelines.
• Familiarity with SRE principles and practices, including SLO/SLI definition, error budget management, and blameless post-mortems.
• Solid understanding of high availability design patterns, active-active/active-passive architectures, and disaster recovery strategies.
• Strong troubleshooting skills across the Linux system stack and network layer.

Preferred Qualifications:

• Experience managing host fleets at scale (thousands of nodes or above) in a production environment.
• Scripting or development experience in Python, Go, or Bash for automation and tooling.
