Senior Platform Engineer (Digital Ecosystem)
About The Position
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. 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 GovCloud 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.
