Full-Stack Platform Engineer - Agentic AI

Peraton•Annapolis Junction, MD

About The Position

Peraton Labs is seeking a Full-Stack Platform Engineer to help build and scale a platform that enables rapid development of secure, AI-powered applications through natural language interfaces, agent builders, and mission-level workflow orchestration. This platform is intended to provide a modern, efficient alternative to traditional data intelligence and application delivery approaches by centralizing common capabilities such as security, access control, reusable platform services, and Agentic AI implementation patterns. The product will help development teams transition toward AI-enabled, spec-based engineering workflows, and accelerating delivery of solutions across a wide range of mission and business use cases. In this position, you will help establish the platform foundation that enables teams to rapidly build and deploy secure Agentic AI solutions. Your work will reduce duplication, accelerate delivery, improve governance, and make advanced AI capabilities more accessible to developers and mission users alike. This role is best suited for a senior cloud/platform engineer who can build secure, scalable, cloud-native platform capabilities and help establish the technical foundation for enterprise-wide adoption of Agentic AI.
