AI Full Stack Developer

The Opportunity:
The candidate will be responsible for designing building and deploying end-to-end web applications that leverage Artificial Intelligence (AI) and Large Language Models (LLMs) within a secure Department of War (DoW) environment. This requires standard full-stack development skills (frontend UI backend APIs and databases) combined with the ability to integrate modern AI pipelines.

Qualifications:

Required:
Backend Development: Advanced proficiency in Python and API frameworks (e.g. FastAPI Flask) to build the core logic and connect user interfaces to AI models.
Frontend Development: Experience building clean intuitive user interfaces using modern frameworks (e.g. React Vue) or AI-focused UI libraries (e.g. Streamlit) for chat interfaces and search dashboards.

AI Data Integration (RAG): Hands-on experience designing and implementing Retrieval-Augmented Generation (RAG) workflows to allow the AI to securely reference and search internal documents.
DevOps & Infrastructure: Experience containerizing applications using Docker/Podman and utilizing version control (Git) to package applications for stable deployment.


Desired:
Secure / Air-Gapped Deployment: Understanding of how to deploy containerized applications in restricted disconnected or IL5 environments without relying on active external cloud connections.
Open-Source AI Ecosystem: Experience utilizing the Hugging Face library/hub to evaluate download and implement open-weight models (e.g. Llama 3 Mistral) locally.
Local Compute Optimization: Familiarity with model runtime tools (e.g. vLLM ) and quantization techniques (e.g. GGUF) to run large AI models efficiently on standard DoD hardware.
AI Orchestration Frameworks: Familiarity with frameworks like LangChain or LlamaIndex to accelerate the development of complex AI agent workflows.
AI Safety & Evaluation: Ability to implement system guardrails to prevent off-topic outputs and mitigate AI hallucinations ensuring secure and accurate mission-support tools.
