Senior Full-Stack Platform Engineer Agentic AI

Peraton Labs is seeking a Senior 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.

Key responsibilities may include but are not limited to:

• Design build deploy and maintain core platform services supporting an Agentic AI platform in cloud environments such as AWS Azure or similar
• Engineer scalable platform capabilities for agent orchestration workflow execution API integration identity and access control observability and secure application enablement
• Build reusable infrastructure and shared services that reduce developer overhead and accelerate delivery of AI-enabled applications
• Develop cloud-native solutions using containerization microservices API-first design infrastructure-as-code (IaC) and automated deployment pipelines
• Implement secure platform controls including authentication authorization secrets management auditing and policy enforcement
• Partner with software engineers architects product teams and security stakeholders to define platform requirements technical standards and implementation priorities
• Improve platform reliability and operational maturity through monitoring logging tracing alerting and performance optimization
• Support integration of AI/LLM capabilities into a cohesive platform architecture
• Troubleshoot complex platform cloud and deployment issues in development and production
• Document platform architecture engineering standards and operational best practices
• Contribute as a senior technical team member by helping shape platform direction and mentoring other engineers as needed
• Design and implement RESTful API endpoints using FastAPI maintain API contracts with frontend consumers and implement OpenAI-compatible API endpoints with token streaming
• Develop and extend the plugin lifecycle system: packaging validation deployment activation and lifecycle hook execution across worker service and library plugin types
• Manage database operations using SQLModel/SQLAlchemy with PostgreSQL implement schema migrations and maintain configuration management
• Write unit and integration tests enforce code quality) and contribute to CI/CD pipelines
• Collaborate with frontend engineers to deliver cohesive user experiences and where possible contribute to frontend development of platform UI supporting components and frameworks
