Familiarity with CI/CD pipelines (GitLab CI).
Experience with VS Code and AI extensions such as Claude Code.

Responsibilities

Generative AI & LLM Solution Delivery: Lead design, development, prototyping, and refinement of AI-powered capabilities using generative AI, large language models, retrieval patterns, prompt/context engineering, and secure API integrations.
Agentic AI System Development: Own end-to-end agentic AI development lifecycles, including model selection, agent design, tool/function calling, orchestration, response synthesis, evaluation, and deployment of reliable AI agents.
Senior Software Engineering Leadership: Apply strong software engineering principles to design maintainable, testable, and scalable systems; conduct code reviews, establish technical patterns, and leverage AI-assisted development tools responsibly to accelerate delivery.
Cross-Functional Technical Collaboration: Partner with data engineers, software engineers, data scientists, cloud engineers, and mission stakeholders to translate business and mission needs into operational AI and automation solutions.
Cloud Enablement & DevSecOps Integration: Design and automate deployment workflows using Infrastructure as Code (IaC), CI/CD pipelines, containers, and cloud-native services to support secure, repeatable, and scalable AI delivery.
Production Monitoring & Optimization: Monitor AI systems post-deployment, perform performance tuning, and apply best practices for reliability and scalability.
Technical Rigor & Documentation: Write clean, well-documented code following industry and federal guidelines; support reproducible development.
Technical Mentorship & Continuous Improvement: Stay current on emerging AI/ML trends, agentic frameworks, model capabilities, and engineering practices while mentoring team members and contributing to reusable standards, documentation, and technical design reviews.
