• Build and maintain LLM integrations, RAG and advanced RAG pipelines, embeddings, semantic retrieval, vector search, agentic workflows, and AI-enabled automation.
• Develop secure AI applications, APIs, backend services, user interfaces, dashboards, integrations, and workflow components.
• Provide hands-on development, integration, testing, troubleshooting, deployment, and operational support.
• Implement model evaluation, hallucination reduction, retrieval-quality tuning, grounding validation, monitoring, and performance optimization.
• Maintain knowledge-base ingestion and refresh processes, embedding regeneration, vector-database configurations, and retrieval-relevance monitoring.
• Implement and enforce environment controls across DEV, TEST, STAGING, and PROD.
• Ensure changes complete applicable unit testing, automated security scanning, model evaluation, accessibility testing, and TEVV gates before production.
• Manage secrets using approved FedRAMP-authorized secret-management capabilities and prevent hardcoded or shared credentials.
• Support MLOps workflows, model and prompt versioning, drift detection, retraining support, CI/CD, release documentation, and production monitoring.
• Conduct code reviews, prompt reviews, technical reviews, troubleshooting, and technical mentoring.
• Conduct AI-specific adversarial testing, including:
• • Prompt injection
  • Jailbreak attempts
  • Data poisoning
  • Unsafe output
  • Unauthorized disclosure
  • Retrieval manipulation
  • Credential exposure
• Document findings, implement mitigations, perform retesting, and support release decisions.
• Support ATO activities, security assessments, vulnerability remediation, privacy documentation, SBOM development, and compliance evidence.
• Support AI applications that meet Section 508 and WCAG 2.1 Level A and AA requirements.
• Serve as a Tier 2 and Tier 3 helpdesk escalation resource.
• Be reachable within two hours for Tier 2 or Tier 3 tickets opened during business hours.
• Provide after-hours escalation support for critical and high-severity AI incidents.
• Support production issue triage, root-cause analysis, service restoration, user support, and continuous improvement.
