Principal Platform Engineer

Principal Platform Engineer

We are seeking a Principal Platform Engineer to design, build, and implement scalable, secure infrastructure solutions across commercial and CMMC Level 2 environments. This is a highly hands-on role focused on solving complex infrastructure challenges, developing reusable platform capabilities, and driving automation across cloud and hybrid environments s role is ideal for engineers who prefer building and solving complex problems over producing static architecture artifacts.

Responsibilities:

• Design and implement scalable infrastructure solutions across AWS, on-prem, and hybrid environments
• Build and maintain reusable Infrastructure as Code (IaC) modules and platform components
• Develop and enforce secure-by-design solutions aligned to CMMC Level 2 and enterprise security requirements
• Partner with Security Architecture and GRC to translate security and compliance requirements into implementable controls
• Lead the implementation of network segmentation, identity integration, logging, and monitoring solutions
• Drive adoption of automation-first practices, including CI/CD pipelines and Policy as Code (PaC)
• Solve complex platform and infrastructure challenges through hands-on engineering and rapid iteration
• Contribute to and refine platform standards, patterns, and reference implementations through working code
• Support and mentor engineering teams on best practices for infrastructure, automation, and platform design
• Evaluate and integrate new technologies (including AI-enabled platforms) with a focus on practical implementation and risk alignment

Required Qualifications:

• 8+ years in cloud engineering, platform engineering, or infrastructure roles
• Strong hands-on experience designing and building in AWS (multi-account environments preferred)
• Deep experience with Terraform or similar IaC tools
• Strong understanding of networking, identity, and security implementation
• Experience implementing solutions in regulated or compliance-driven environments (CMMC, NIST, etc.)
• Experience building and integrating CI/CD pipelines for infrastructure
• Strong scripting or programming skills (Python, Bash, or similar)
• Proven ability to take solutions from design through implementation and operation

Preferred Qualifications

• Experience in hybrid environments (on-prem + cloud)
• Familiarity with Dev Ops and platform engineering operating models
• Experience implementing zero trust or modern security architectures
• Experience integrating infrastructure platforms with enterprise systems (e.g., identity providers, ITSM, monitoring)
• Exposure to container platforms and Kubernetes

Core Competencies:

• Systems thinking and platform design mindset
• Ability to balance long-term architecture with practical delivery
• Strong written and verbal executive communication
• Player-coach mentality: willing to design and build
• High ownership and bias for automation
