About Coalfire

Coalfire is on a mission to make the world a safer place by solving our clients’ hardest cybersecurity challenges. We work at the cutting edge of technology to advise, assess, automate, and ultimately help companies navigate the ever-changing cybersecurity landscape. We are headquartered in Chicago, Illinois with offices across the U.S. and U.K., and we support clients around the world.

But that’s not who we are – that’s just what we do.

We are thought leaders, consultants, and cybersecurity experts, but above all else, we are a team of passionate problem-solvers who are hungry to learn, grow, and make a difference.

Position Summary

Coalfire is looking for an experienced Cloud Infrastructure Engineer to support our DivisionHex group. In this role, you will work closely with internal development and operations teams to design, deploy, and maintain internal AWS infrastructure used during penetration testing and other security service engagements.

The ideal candidate will have extensive experience designing and deploying complex AWS environments using infrastructure-as-code, particularly the AWS CDK, to ensure consistency and change control. While experience in information security is valued, it is not required—we welcome candidates with strong infrastructure backgrounds who are interested in supporting security-focused use cases.

This position requires regular access to Coalfire's Alpharetta, GA office to administer and manage physical devices. The role expects up to 3 days per week in-office presence, or as operational demand dictates.

• Maintain in-depth knowledge of AWS services, architecture, and infrastructure best-practices
• Provide guidance and troubleshooting for internal infrastructure deployments
• 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)
• Professional-level AWS Certification(s) (Solutions Architect, DevOps Engineer)
• 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
• Outstanding written and verbal communication skills and attention to detail
• Desire to learn new technologies and use those to improve efficiency, scalability, and reliability of internal infrastructure
