Job Description

Responsibilities

Peraton Labs is seeking a senior engineer to serve as the technical lead for the multi-agent generative AI orchestration layer that powers an advanced analytical platform. This role owns the architecture governing how multiple LLM-based worker agents are spawned, routed, coordinated, and managed across diverse analytical tasks. The Senior LLM/AI Platform Engineer ensures that the platform's generative AI backbone is reliable, performant, and extensible as new worker types and capabilities are introduced.

Key Responsibilities

• Architect and maintain the multi-agent orchestration framework, including worker spawning, conversation history isolation, context management, and inter-worker coordination
• Design and implement token optimization strategies, including context window management, conversation summarization, and efficient prompt construction
• Own the model routing layer that directs tasks to appropriate model tiers based on task complexity and user configuration
• Develop and refine prompt engineering patterns for worker agents to ensure consistent, high-quality analytical outputs
• Establish evaluation frameworks to measure generative AI output quality, accuracy, and reliability across worker types
• Lead the design of new worker types to support program management capabilities (cost analysis workers, risk analysis workers, data fusion workers)
• Collaborate with PM Domain Analysts to translate program management requirements into generative AI agent behaviors
• Mentor junior LLM/AI Platform Engineers and establish engineering standards for generative AI development

Qualifications

Required Qualifications

• Minimum of 8+ years of experience with a Bachelor's degree, 6+ years with a Master's degree, or 3+ years with a PhD in Computer Science, AI/ML, or related field
• Deep experience with large language model architectures, fine-tuning, and inference optimization
• Proficiency in Python; experience with LLM frameworks (LangChain, LlamaIndex, or equivalent)
• Strong understanding of prompt engineering, retrieval-augmented generation (RAG), and agent-based architectures
• Experience with vector databases and embedding models
• Demonstrated ability to architect complex, multi-component generative AI systems
• US Citizenship with the ability to obtain/maintain a Secret clearance

Preferred Qualifications

• Experience with multi-agent systems or autonomous agent frameworks
• Familiarity with government/defense program management concepts
• Experience with model evaluation and red-teaming methodologies
• Knowledge of FedRAMP or DoD cloud security requirements
