About the Role

We are seeking a Senior Platform Engineer to drive the design, development, and scalability of our core cloud infrastructure and platform systems. This is a hands-on role at the intersection of cloud architecture, reliability, automation, and security. You will play a key part in building and maintaining robust, secure, and compliant environments, ensuring our systems meet the needs of a dynamic, fast-growing organization.

What You'll Do

• Architect, implement, and optimize scalable cloud infrastructure solutions.
• Deploy and manage infrastructure using Terraform and infrastructure-as-code best practices.
• Automate operational processes, monitoring, and deployments with modern CI/CD pipelines (e.g., GitHub Actions).
• Identify, remediate, and prevent security vulnerabilities across cloud and application stacks, including containers.
• Collaborate with engineering teams to integrate security, compliance, and reliability into the software development lifecycle.
• Evaluate and improve cloud security controls aligned with NIST and other relevant compliance frameworks.
• Monitor and troubleshoot cloud infrastructure, applications, and networking components for performance and reliability.
• Contribute to technical decisions around architecture, tool selection, and infrastructure improvements.
• Support continuous improvement of security posture and compliance programs.

What We're Looking For

• 3+ years of professional experience in platform engineering or DevOps roles.
• Proven professional experience with Terraform and infrastructure-as-code.
• Hands-on experience designing and managing cloud infrastructure (preferably AWS).
• Strong foundation in cloud security, vulnerability remediation, and infrastructure reliability.
• Experience building, maintaining, and optimizing CI/CD automation.
• Solid programming or scripting ability (e.g., Go, Python, Bash).
• Experience identifying and resolving container and cloud infrastructure vulnerabilities.
• Familiarity with compliance standards (e.g., NIST, SOC 2, FedRAMP) and their technical requirements.
• Strong analytical, troubleshooting, and problem-solving skills.
• Ability to work independently and in cross-functional, remote engineering teams.

Preferred Qualifications

• Experience managing or maintaining regulated/FedRAMP-compliant environments.
• Direct experience with AWS security services and controls.
• Experience with Kubernetes and container security.
• Experience with vulnerability management and automated security testing.
• Experience supporting government or highly regulated clients.

What Will Set You Apart

We’re looking for candidates who can architect, troubleshoot, and operationalize core infrastructure in cloud environments—balancing reliability, compliance, and performance. You will thrive if you have experience going beyond compliance checkboxes to implement and scale robust, secure systems, and are eager to take on increasing technical and organizational responsibility as our organization grows.

Growth Opportunity

This role offers considerable growth potential. As our environment and engineering teams scale, this position provides a unique path toward ongoing technical leadership and broader architecture responsibilities.
