Key Responsibilities

AI Application Development

• Design, develop, integrate, deploy, and enhance AI-enabled applications, services, and user interfaces, building LLM integrations, RAG pipelines, embeddings, vector search, and agentic workflows via Model Context Protocol (MCP) engineered to the Government’s AI agent security framework, with prompt and context engineering, structured outputs, model orchestration, and retrieval quality controls (chunking, hybrid retrieval, relevance scoring, grounding validation), ensuring compliance with Section 508 / WCAG 2.1 A and AA.

Evaluation, Testing, and AI Security

• Implement model evaluation, hallucination reduction, retrieval tuning, and performance optimization; plan and oversee functional, regression, performance, accessibility, adversarial, model-quality, and user acceptance testing; conduct AI-specific adversarial testing (prompt injection, jailbreak, data poisoning) before each release, documenting and mitigating findings; and maintain the RAG knowledge-base refresh schedule, escalating any retrieval-relevance decline.

DevSecOps, MLOps, and Releases

• Enforce promotion controls across environments (security scans, unit tests, TEVV gates, secrets in Government-furnished vaults), support MLOps workflows (versioning, drift detection, retraining, release documentation), and prepare release packages, Software Bills of Materials (SBOMs), and ATO/security-assessment/vulnerability-remediation support.

Operations and Support

• Serve as a Tier 2 / Tier 3 helpdesk escalation resource for critical and high-severity incidents, and support production operations, root-cause analysis, issue triage, and continuous improvement.

Deliverables You Will Own

• AI/RAG Pipeline Designs; AI System Test Plans; Configuration Management Plan; Evaluation and Adversarial Testing Reports; Software Bills of Materials; and co-authorship of the AI Security Certification Package.

Team Leadership

• Conduct code and prompt reviews, mentor developers, and act as the primary technical backup for the Lead AI Engineer.
