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 at scale.

This role is ideal for engineers who prefer building and solving complex problems over producing static architecture artifacts.

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

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.)

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

Experience in hybrid environments (on-prem + cloud)

Familiarity with DevOps 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

• 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
