• Build, own, and improve GitHub Actions workflows for infrastructure CI/CD pipelines across networking,

identity, and platform services, including pipeline reliability and security controls.

patterns and guardrails across AWS accounts.

• Lead deployment and management of IAM Identity Center (IAM IC) configurations, Permission Sets, and

account assignments through IaC, including lifecycle management and compliance reviews.

• Independently troubleshoot and resolve complex network connectivity, latency, and routing issues across

AWS and Cloudflare environments, and document root cause findings.

• Serve as an escalation point during sprint-based support rotations for platform issues, and drive

improvements to reduce recurring incidents.

• Partner with cloud engineering, security, and application teams to translate approved architectures into

production-ready networking and identity solutions, taking ownership from design through delivery.

• Lead documentation efforts for runbooks, architecture decisions, and knowledge-sharing; mentor Level I

engineers on team standards and best practices.

• Own and improve account vending processes using enterprise automation tools, driving consistency and

reducing manual steps.

• Maintain, enhance, and proactively improve automated provisioning pipelines for infrastructure hosting.
• Define and enforce account guardrails through infrastructure as code policies, contributing to the broader

governance framework.
