Peraton Labs is seeking an experienced Senior Full-Stack Software Engineer to join an existing engineering team developing a prototype RF spectrum planning and monitoring system for Department of Defense clients.

The ideal candidate brings strong full-stack fundamentals and the professional maturity to operate effectively with minimal direction. This individual will be expected to develop a thorough understanding of the application and its users, proactively identify opportunities for improvement, and deliver well-considered solutions without requiring explicit task definition at every step.

Success in this role requires technical depth across the stack, sound judgment about where to focus effort, and the communication skills to remain well-aligned with a team that spans software engineers, domain experts, and DoD stakeholders.

Key responsibilities may include:

• Build and improve features across the full stack — React frontend, FastAPI backend, and TypeScript/Node.js services
• Understand user workflows and use cases; identify improvements without waiting for explicit guidance
• Develop and maintain REST APIs and containerized services (Docker)
• Write clean, testable Python and JavaScript/TypeScript code
• Engage with program leadership and stakeholders to clarify requirements and validate solutions
• Maintain technical documentation for architecture, APIs, and integrations
• Contribute to code reviews and testing
