The Role Peraton is seeking a talented and motivated Full Stack & Dev Sec Ops  Engineer to join a dynamic team building and operating a cutting-edge Agentic AI platform. This hybrid role sits at the intersection of application engineering and platform operations - combining the responsibilities of a Full Stack Engineer specializing in Agentic AI and External Integrations with those of a Dev Sec Ops  / Platform Engineer.

In this role, you will design, develop, and maintain the integrations and intelligent agent capabilities that power a next-generation decision-support platform, while also owning the delivery infrastructure, CI/CD pipelines, cloud operations, and platform health that keep it running securely and reliably. You will work across the full stack to connect AI agents with diverse external data sources, package real-world capabilities as reliable agent tools, and ensure that the systems you build are secure, scalable, observable, and production ready.

If you are passionate about applied AI, thrive in fast-moving environments, and take pride in building platforms that real users depend on - from the application layer down to the infrastructure - this is an opportunity to make a meaningful impact supporting critical missions.
