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 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.

Responsibilities:

• Lead and support the design, implementation, automation, configuration, integration, and sustainment of secure platform environments across AWS GovCloud, 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 GovCloud 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.

About Us: PMAT is an innovative small business founded with a passion for developing forward-leaning solutions from exceptional people that increase the mission's capability. We focus on designing and building impactful digital solutions that utilize modern cloud, data, and software concepts. Our passion is working on complex and progressive challenges such as edge platform computing, containerizing legacy platforms, distributed data platforms, or heterogeneous data analysis.

We recruit, retain, and foster a team motivated to pursue passions, investigate new ways of doing things, and embody an innovative and entrepreneurial spirit. We believe in being curious about every element of a problem and experiment relentlessly. We foster continuous learning in an environment that encourages positive collaboration and expands our capabilities. We tap into collective intelligence, acknowledging that the most brilliant people may not be in the room. Above all else, we believe that delivering and demonstrating is more potent than a sheet of paper. We are passionate about mission-centric design and delivering effective capabilities to and for the warfighter.

Whether you’re an experienced engineer or just beginning your career, you’ll work alongside experts who are committed to solving mission-critical problems. If you’re passionate about using your skills to make a real difference, apply today and become part of a team that’s shaping the future of defense technology!
