Platform Engineer (Digital Ecosystem) - Secret Clearance Required

Senior Platform Engineer

At PMAT, we work on mission critical systems that directly support the warfighter, designing, building, and securing modern digital capabilities across cloud, data, and software environments. Our teams tackle complex, real-world challenges where delivery matters more than theory, and innovation is driven by curiosity, collaboration, and purpose.

In this role, you'll contribute to Naval Operational Architecture (NOA), working alongside engineers and operators to deliver resilient, forward-leaning solutions in support of national defense.

About the role:

PMAT is seeking a highly experienced Senior Platform Engineer to support the design, automation, deployment, integration, sustainment, and modernization of secure cloud and platform environments for advanced Navy and DoD capabilities. This role emphasizes Infrastructure as Code (IaC), scripting, automation, AWS Gov Cloud engineering, and secure platform operations across enterprise, cloud, containerized, and hybrid environments. The candidate will work with cross-functional engineering, cybersecurity, development, and operational teams to build and maintain scalable, repeatable, secure, and mission-ready platform solutions.

The role requires strong technical judgment, hands-on engineering capability, and the ability to support both tactical implementation and strategic platform modernization across dynamic mission environments.

Responsibilities:

• Lead and support the design, implementation, automation, configuration, integration, and sustainment of secure platform environments across AWS Gov Cloud, enterprise, containerized, and hybrid architectures.
• Develop, maintain, and improve Infrastructure as Code solutions to automate provisioning, configuration, deployment, monitoring, and sustainment of cloud and platform resources.
• Use scripting and automation to streamline platform operations, reduce manual processes, improve repeatability, support troubleshooting, and enable efficient system administration across mission environments.
• Support AWS Gov Cloud infrastructure development and operations by configuring, integrating, monitoring, and troubleshooting compute, storage, networking, identity, security, logging, and automation services.
• Engineer and maintain operating system, identity, authentication, networking, storage, and application hosting environments to support secure and reliable mission platform operations.
• Support containerized application platforms and orchestration environments by assisting with deployment, configuration, scaling, monitoring, troubleshooting, and sustainment activities.
• Apply cybersecurity and platform hardening practices by supporting secure configuration management, vulnerability remediation, patching, access control, compliance activities, and audit-ready documentation.
• Provide senior-level technical leadership across cross-functional teams by troubleshooting complex platform issues, coordinating engineering priorities, documenting technical solutions, mentoring team members, and communicating technical risks and recommendations to program stakeholders.
