AI Engineer

• Own our fine-tuning strategy end-to-end — LoRA first, full fine-tunes where they earn it. What we tune, on what hardware, against what evals
• Define the GPU architecture. We have working infrastructure (H100 for production, A100 for training); your call to confirm, reshape, or rebuild
• Drive model selection and routing across Gemini, Anthropic, and OpenAI — the right model for the right job, with cost and latency in the equation
• Build agentic LLM pipelines using LangChain, LangGraph, and LangSmith
• Design and iterate on prompt strategies, with a focus on consistency and context
• Construct retrieval-augmented generation (RAG) systems from scratch
• Instrument evaluation metrics, telemetry, and feedback loops to guide model and prompt evolution
• Work alongside product, frontend, and backend engineers to tightly integrate AI into user-facing flows
