Job Summary

Your Impact

• Intelligent Provisioning: Configure and support resilient hybrid cloud deployments. You will move beyond manual scripting by adopting AI-driven automation frameworks to make infrastructure delivery more efficient and error-free.
• Predictive Scalability: Manage capacity planning and resiliency by adapting AI modeling to forecast resource needs and prevent bottlenecks before they occur.
• Autonomous Operations: Maintain service availability and performance SLAs. You will design self-healing systems that leverage AI for automated incident remediation and proactive service monitoring.
• Incident Leadership: Lead and manage P1/P2 incident response for all business-critical applications and platforms. You will ensure service availability by driving rapid resolution, leveraging AI-assisted diagnostics and automated playbooks to protect global SLAs.
• Infrastructure Evolution: Work with other SREs to deploy automation frameworks and create operational runbooks that incorporate Generative AI for faster documentation and knowledge sharing.
• Trend Analysis: Design proactive monitoring and alerting systems that use machine learning for deep-dive trend analysis of underlying infrastructure.

• Linux Expert: 6-10 years of hands-on experience managing and supporting Linux (RHEL/Ubuntu) at scale. Deep knowledge of kernel tuning and system internals is a must.
• Automation Specialist: Mastery of Ansible, Chef, or Terraform. You should be comfortable adapting these tools to integrate with AI APIs for intent-based infrastructure management.
• Cloud Orchestration: Proven experience provisioning and supporting resilient architectures in at least one major cloud environment (GCP/GKE, AWS, or Azure). You understand how to maintain a cloud footprint that is efficient, secure, and highly available.
• Critical Incident Management: Proven track record leading P1/P2 incident bridges and post-mortems for complex, global application stacks. You are an expert at protecting SLAs through technical leadership and automated remediation.
• Automated Patching & Security: Lead the end-to-end patching and vulnerability management process. You will be expected to modernize this "much-needed" function by implementing automated, AI-assisted patching cycles that minimize downtime and ensure CIS compliance.
• AI Integration: Experience or a strong interest in adopting AI coding assistants (like GitHub Copilot or Claude) to accelerate "vibe coding" workflows-focusing on high-level architecture and intent while AI handles the boilerplate.
• API & Scripting : Expertise in developing and managing APIs, with a focus on optimization and security for multi-tier applications.
• Security & Hardening: Fluent in Linux security, vulnerability management, and CIS compliance. You understand how to secure infrastructure in an AI-first world.
• The Modern Mindset: You possess the "vibe coding" spirit-leveraging AI to solve complex problems faster without losing the critical eye of a senior engineer. You have the passion, drive, and sense of humor to thrive in a global, fast-paced team.
