A Career that Empowers You to Build Your Future
Join the Cloud Platform team as a Cloud Platform Engineer focused on network and identity infrastructure in AWS
and Cloudflare. In this role, you will implement and maintain cloud networking and identity services through a fully
code-driven infrastructure model. Using Terraform, GitHub Actions, and DevOps practices, you will build and
operate scalable, well-governed platform services in a multi-account AWS environment. While AWS is the primary
platform and the target for all new development, the organization maintains a legacy Azure presence that may
require occasional support.
Your Responsibilities on the Team
• Design, implement, and own AWS networking constructs such as VPCs, subnets, route tables, and
internet/NAT gateways using IaC and CI/CD workflows, with accountability for reliability and standards
compliance.
• Lead Transit Gateway configurations to support multi-account and multi-region connectivity, including
architecture decisions and ongoing optimization through infrastructure as code.
• Implement and own AWS Direct Connect configurations for hybrid connectivity, including troubleshooting
complex routing issues between on-premises and cloud environments.
• Design and enforce network security controls including Security Groups, Network ACLs, and VPC endpoint
policies through reusable, well-documented IaC modules.
• Own and administer AWS Network Firewall configurations, including policy development and integration with
broader platform security controls.
• Lead the design and implementation of Cloudflare services including DNS, CDN, WAF, and traffic
management through infrastructure as code, serving as a subject matter expert for the team.
• Develop, maintain, and establish standards for reusable IaC modules for network and identity infrastructure
deployments across teams.
• Build, own, and improve GitHub Actions workflows for infrastructure CI/CD pipelines across networking,
identity, and platform services, including pipeline reliability and security controls.
• Design and implement IAM roles, policies, and trust relationships as code, establishing least-privilege access
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.
• Drive continuous improvement initiatives in cloud usage, automation coverage, and operational efficiency
across the platform.
Your Toolbox
• Bachelor's degree in Computer Science, Information Technology, or a related field preferred.
• 2-3 years of experience working with AWS platform and infrastructure services.
• Hands-on experience with Terraform for infrastructure as code.
• Working knowledge of GitHub and GitHub Actions for CI/CD.
• Solid understanding of AWS networking services: VPC, Transit Gateway, Direct Connect, Route 53, Elastic
Load Balancing, and VPC endpoints.
• Familiarity with AWS identity and access management: IAM roles and policies, IAM Identity Center,
Permission Sets, and trust policies.
• Understanding of network security constructs: Security Gro
