Key Responsibilities
AI Application Development
- Design, develop, integrate, deploy, and enhance AI-enabled applications, services, and user interfaces.
- Build and maintain LLM integrations, Retrieval-Augmented Generation (RAG) pipelines, embeddings, vector search, agentic workflows, and AI-enabled automation.
- Implement prompt and context engineering, structured outputs, model orchestration, and retrieval quality controls such as chunking, hybrid retrieval, relevance scoring, and grounding validation.
- Ensure AI-enabled applications and interfaces meet security, privacy, and Section 508 / WCAG 2.1 A and AA accessibility requirements.
Evaluation, Testing, and AI Security
- Implement model evaluation, hallucination reduction, retrieval quality tuning, monitoring, and performance optimization, including side-by-side comparisons for model upgrades.
- Plan and oversee unit, integration, functional, regression, performance, load, accessibility, adversarial, model-quality, and user acceptance testing.
- Conduct AI-specific security and adversarial testing (prompt injection, jailbreak, data poisoning, unsafe output, unauthorized disclosure) before each release, and document and mitigate findings.
- Maintain the RAG knowledge-base refresh schedule and escalate any retrieval-relevance decline.
DevSecOps, MLOps, and Releases
- Enforce promotion controls across environments, including security scans, unit tests, and TEVV gates, with secrets kept in Government-furnished vaults.
- Support MLOps workflows, including model versioning, drift detection, retraining, and release documentation.
- Prepare release packages and Software Bills of Materials (SBOMs), and support ATO, security assessment, and vulnerability remediation activities.
Operations and Support
- Serve as a Tier 2 / Tier 3 helpdesk escalation resource, reachable within business hours and providing escalation support for critical and high-severity incidents.
- 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.
Requirements
- Bachelor's degree in Engineering, Computer Science, Systems, or a related scientific/technical discipline and 5+ years of relevant experience.
- 5+ years of hands-on experience in AI/ML engineering, AI-enabled application development, data engineering, cloud engineering, or software engineering, including direct development, integration, testing, and operational support of AI-enabled systems.
- 1+ year of hands-on experience with Generative AI, LLM integration, RAG, model evaluation, agentic AI, or production AI systems.
- Strong proficiency in Python and experience developing AI-enabled applications, APIs, services, and automation.
- Experience designing and deploying RAG pipelines, semantic retrieval, vector databases, cloud-based AI services, and AI workflow orchestration.
- Knowledge of AI testing, model evaluation, Responsible AI practices, and AI security controls in secure enterprise or federal cloud environments.
- Experience conducting AI-specific and adversarial testing (prompt injection, jailbreak, data poisoning) and documenting mitigations.
- Experience developing AI-enabled user interfaces that conform to Section 508 / WCAG 2.1 A and AA.
- Experience supporting release management, documentation, monitoring, and operational support.
- At least one current Generative AI or Machine Learning certification, such as Microsoft Azure AI, AWS, Google Cloud, Databricks, NVIDIA, or CAIP, or an equivalent.
- Must be a U.S. citizen or lawful permanent resident (green card holder).
- Must reside in the Washington, DC metropolitan area and be able to work on-site at Government offices.
- Must be able to pass and maintain a Government background investigation.
Preferred Qualifications
- Master's degree in a related field and 7+ years of experience, including federal agency programs.
- Experience with a modern front-end framework (e.g., React or Angular with TypeScript) and with containers (Docker/Kubernetes) and CI/CD tooling.
- Experience with agentic AI frameworks (e.g., LangGraph, LlamaIndex, Semantic Kernel), MCP, and open-weight model serving (e.g., vLLM, TGI).
- Experience in FedRAMP High or GovCloud environments and with SBOM formats (CycloneDX or SPDX).
- Experience with AI-assisted accessibility remediation or document processing (OCR, PDF tagging).
- A current, favorably adjudicated federal background investigation.
