Daily Responsibilities

• Serve as a senior, hands-on full-stack AI engineer, leading the design, development, and delivery of large-scale mission-critical AI systems.
• Serve as a senior technical lead, defining AI and application architecture for the platform in partnership with and under the direction of the Director.
• Establish enterprise modernization roadmaps aligned to mission outcomes, compliance, and scalability.
• Lead architecture for distributed, cloud-native, and hybrid AI systems.
• Define and enforce reference architectures, standards, and reusable frameworks.
• Drive cross-program technical decision-making to ensure interoperability, security, and long-term sustainability.
• Lead design, development, and deployment of advanced AI solutions, including large language models (LLMs) and foundation models, Retrieval-Augmented Generation (RAG) systems, agentic workflows, and orchestration frameworks.
• Architect and implement scalable AI applications and services using Next.js, cloud-native APIs, and managed AI services across AWS, Azure, and GCP.
• Build full-stack AI applications end to end, from user-facing interfaces to back-end services, APIs, and data layers.
• Integrate AI and LLM capabilities into existing enterprise applications and legacy platforms (e.g., content management, case management, and records systems) via APIs, middleware, and event-driven patterns.
• Oversee the full AI solution lifecycle: data pipelines, evaluation, deployment, and monitoring.
• Drive LLM performance and cost optimization (e.g., caching, prompt and context optimization, model selection).
• Establish robust MLOps practices leveraging GitHub-based automation, CI/CD pipelines, and tooling.
• Stand up the enterprise CI/CD-to-AI/MLOps pipeline, beginning with time-boxed proofs of concept and MVP implementations that mature into production systems.
• Serve as SME in federal AI policy (e.g., NIST AI RMF, OMB M-25-21 and M-25-22, Executive Order 14179).
• Define and operationalize Responsible AI frameworks, including model validation and evaluation, bias mitigation and fairness, and explainability, auditability, and safety.
• Ensure compliance with FISMA, FedRAMP, NIST 800-53, privacy, and Section 508 requirements.
• Lead large-scale modernization initiatives (e.g., legacy-to-cloud, microservices transformation, including refactoring and re-platforming efforts).
• Define repeatable modernization frameworks and accelerators.
• Oversee DevSecOps pipelines and CI/CD automation (e.g., GitHub Actions), zero-trust architectures, and secure software supply chain practices.
• Ensure delivery of resilient, high-availability systems in regulated federal environments.
• Lead multiple concurrent engineering efforts across integrated teams.
• Provide technical leadership to architects, engineers, and DevSecOps specialists, including establishing coding standards and engineering best practices.
• Mentor senior engineers and technical leaders; elevate engineering excellence and code quality.
• Support technical strategy in proposals, captures, and client engagements.
• Contribute to thought leadership (whitepapers, architecture patterns, platform strategy).
