• Create and publish technical documentation and internal knowledgebase articles
• Monitor and optimize infrastructure performance, cost, and reliability
• Continually review personal performance metrics to ensure goals are consistently met
• May perform other duties and responsibilities that management may deem necessary from time to time
• Experience with Google Cloud Platform (GCP), particularly VPC configuration and network troubleshooting, is a plus
• Support and maintain enterprise-grade physical systems and specialized devices used by Division Hex consultants for security testing activities
• Provide technical support and troubleshooting assistance to users for cloud infrastructure and physical device issues (excluding general IT helpdesk support for laptops/desktops)

What You'll Bring

• Ability to work on-site at Coalfire's Alpharetta, GA office up to 3 days per week (or as demand dictates) to support physical device administration and management
• Bachelor's degree in computer science, information technology, or related field (or equivalent experience)

• Strong Python skills with proven experience using Python to automate infrastructure deployment and management
• Experience with infrastructure-as-code and deployment automation in AWS
• 3+ years of hands-on experience with AWS CDK for infrastructure-as-code development (CloudFormation experience also valued)
• 5+ years of experience supporting cloud architecture, design, implementation, operations, and automation in AWS
• Experience gathering requirements from internal stakeholders and refining them into actionable infrastructure designs
• Information security experience or interest is valued but not required
• Ability to multi-task and manage multiple priorities in a fast-paced, agile environment
• Ability to support internal teams with infrastructure troubleshooting and technical support
