Role: Lead AI Engineer
Location: Lake Mary, FL
Duration: 6 months contract
Rate: $75/hr on C2C
Role Overview
We are seeking experienced Senior / Lead AI Engineers to design, build, and productionize enterprise Generative AI solutions. This onsite role combines strong Java and Spring Boot engineering with hands-on expertise in LLMs, prompt engineering, OpenAI and Azure AI integration, RAG, AI security, and model evaluation. The engineer will collaborate directly with business, architecture, product, and engineering stakeholders in Lake Mary.
Key Responsibilities
Design and develop enterprise-grade AI-enabled applications using Java, Spring Boot, REST APIs, and microservices.
Build and integrate LLM and Generative AI capabilities into business applications and workflows.
Develop and optimize system prompts, structured prompts, few-shot prompts, reusable prompt templates, and context-management strategies.
Integrate applications with OpenAI APIs, Azure OpenAI, Azure AI services, and other frontier AI models.
Design and implement RAG solutions using embeddings, vector search, document retrieval, grounding, and citation patterns.
Evaluate models and prompts for accuracy, groundedness, latency, scalability, security, and cost.
Implement safeguards for prompt injection, sensitive-data exposure, hallucination, authentication, authorization, and responsible AI usage.
Create production-grade logging, tracing, observability, model-response monitoring, fallback, and error-handling mechanisms.
Lead architecture discussions, code reviews, technical troubleshooting, and production issue resolution.
Partner with onsite stakeholders to refine use cases, communicate trade-offs, and move solutions from proof of concept to production.
Mentor engineers and establish reusable standards for AI integration and secure application development.
