• Implement reusable AI components, libraries, and APIs that streamline application development and accelerate delivery across programs.
• Integrate AI models with enterprise systems, APIs, data platforms, vector databases, and cloud-native services to deliver scalable mission capabilities.
• Drive iterative experimentation, prototyping, and model improvement cycles in collaboration with Data Scientists and AI Evaluation Scientists.
• Design and implement advanced prompt strategies, context management layers, retrieval systems, and LLM orchestration logic.
• Build scalable inference services, optimize model performance, and collaborate with LLMOps to enable robust deployment, monitoring, and continuous improvement.
• Translate user needs and mission workflows into intuitive, reliable AI-powered features through active partnership with designers and product teams.
• Implement secure-by-design and trustworthy AI practices, including safety guardrails, input sanitization, content filtering, and integration of evaluation metrics.
• Contribute to internal AI frameworks, code patterns, and shared accelerators that raise delivery quality across the AI & Data Exploitation Practice.
• Mentor junior developers, conduct code reviews, and support engineering excellence across multi-disciplinary AI delivery teams.
• Stay current with emerging AI techniques, libraries, foundation models, and agent frameworks, evaluating their applicability to client missions.
• You will contribute to the growth of our AI & Data Exploitation Practice!

• Ability to hold a position of public trust with the U.S. government.

• Solid understanding of RAG architectures - chunking strategies, embedding models, vector stores, retrieval evaluation
• Experience with at least one LLM orchestration framework (LangChain, LlamaIndex, LangGraph, CrewAI, or equivalent)
• Strong prompt engineering skills - system prompts, few-shot design, chain-of-thought, and iterative refinement
• Experience containerizing and deploying applications with Docker
• Proficiency with Git and collaborative version control workflows
• Ability to read and write REST APIs; comfortable integrating third-party services and models
• Strong communication skills - you will interact with clients and translate fuzzy requirements into working systems

Preferred

• Experience with cloud-native AI services, particularly AWS Bedrock for managed LLM inference
• Familiarity with serverless compute (AWS Lambda) and managed ETL pipelines (AWS Glue) for data ingestion workflows
• Working knowledge of vector and relational data stores including AWS RDS Postgres (pgvector) and OpenSearch
• Container orchestration experience with Kubernetes for deploying and scaling AI services
• CI/CD pipeline experience with Jenkins or similar build orchestration tools
• Observability and logging experience for LLM pipelines - LangSmith, Arize, or equivalent
• Familiarity with LLM evaluation frameworks such as RAGAS or DeepEval for measuring RAG and model quality

• • Hands-on experience with workflow automation platforms - n8n, Prefect, Airflow, or similar
  • Experience with MCP and tool-serving infrastructure (MCPO or similar)
  • Experience designing multi-agent systems with agent-to-agent coordination patterns
