• Leverage Terraform and Infrastructure as Code (IaC) to automate provisioning and ensure consistency across environments.
• Utilize Python and other scripting languages to improve automation and operational efficiency.

Incident Management & Reliability

• Lead investigation and resolution of complex cloud and platform incidents.
• Ensure systems meet or exceed performance, reliability, and SLA expectations.

Cost Optimization & Governance

• Partner cross-functionally to identify and implement cloud cost optimization strategies, including use of cloud financial management tools.
• Ensure platform designs follow operational best practices and support long-term maintainability.

Collaboration & Influence

• Work independently while collaborating across engineering, application, and leadership teams.
• Mentor engineers and influence best practices across cloud, DevOps, and platform engineering functions.

Required Qualifications

• Senior/Staff-level experience designing and managing large-scale IT infrastructure in cloud environments.
• Agentic AI Experience: Hands-on experience with agentic AI systems for infrastructure automation (AI-driven runbook execution, LLM-based ops tooling, autonomous remediation pipelines).
  • minimum 3 years of  production grade Gen AI & Agentic AI implementations experience on cloud, devops, SRE & platform engineering.
• Strong hands-on experience with AWS, including services such as EKS, Lambda, and supporting AWS-native tooling.
• Deep knowledge of Kubernetes, container orchestration, and cloud-native deployment patterns.
• Proven experience with application modernization and migration projects, particularly replatforming legacy applications.
• Strong experience with CI/CD pipelines, GitLab, and DevOps methodologies.
• Experience using Terraform and Infrastructure as Code to manage cloud environments.
• Solid understanding of Linux-based environments OR strong Windows-to-cloud migration experience with the ability to operate in Linux-based platforms.
• Experience driving cost optimization initiatives using data and cloud financial tools.
• Excellent communication and decision-making skills, with the ability to influence across teams.
• Prior experience supporting retail or e-commerce platforms is strongly preferred.

Preferred / Nice-to-Have Skills

• Experience migrating applications from Windows to Linux/container-based environments.
• Exposure to .NET application modernization, including legacy frameworks.
• Experience with Karpenter, cloud capacity optimization, and autoscaling strategies.
• Familiarity with InOps / FinOps practices.
• Strong scripting experience (Python preferred).

Why This Role

• Direct ownership and influence over a major enterprise modernization initiative.
• Opportunity to shape how applications are built, deployed, and operated in a cloud-native environment.
• High-impact role working with modern AWS and Kubernetes technologies at scale.
