AI Engineer

Key Responsibilities Application Development & Integration: Build, test, and maintain production-ready GenAI applications using Lang Chain, Llama Index, Python, and microservices architectures. Implement high-accuracy Retrieval-Augmented Generation (RAG) pipelines for content metadata, sports stats, and knowledge bases. Integrate LLM endpoints into DirecTV s client applications (Gemini OS, iOS, Android, Smart TV apps) via RESTful APIs and WebSockets. Model Fine-Tuning & Evaluation: Fine-tune open-source models (Llama, Mistral) using LoRA/ QLoRA techniques for specialized entertainment and customer care domain tasks.Set up automated evaluation suites (using frameworks like Ragas, TruLens) to measure hallucination rates, latency, relevance, and response accuracy. Prompt Engineering & Orchestration: Develop, optimize, and version-control complex prompts and agent workflows. Implement fallback logic, circuit breakers, and guardrails (NeMo Guardrails, Guardrails AI) to ensure safe, reliable user interactions. Operations & Collaboration: Collaborate with MLOps and Cloud Engineers to set up continuous deployment pipelines (CI/CD) for model artifacts and vector index refreshes. Monitor production inference latency, token usage, and error logs to maintain system reliability.
