Remote GenAI Architect - Build & Operate Production LLMs

Look4IT; United States; Remote; USD 140,000 - 220,000; Full time

Job summary

Look4IT is hiring a Senior AI Engineer to build and operate a production-grade LLM system used by real users. You will take LLM-powered features from idea to deployment, focusing on answer quality, performance, observability, and cost efficiency.

You will work with LangGraph, RAG, tool calling, and Azure OpenAI, Gemini and Claude, delivering end-to-end solutions in a cloud environment. This is a remote, production-focused role with significant impact.

Qualifications

• : Experience in building and operating backend services – APIs, async, testing.
• : Hands-on experience taking LLM features to production and keeping them running – not just prototypes.
• : Knowledge of agent/orchestration frameworks — LangGraph ideally.
• : Practical RAG experience.
• : Experience debugging LLM systems in production – tracing, evaluation, cost and latency.
• : Experience running services in the cloud (Azure).
• : Strong problem-solving skills, analytical thinking, and technical decision-making.
• : Fluent in English, proactive communicator, and a collaborative team player.

Responsibilities

• : Build LLM-powered features end to end. Design and implement agentic flows, retrieval, and tool calling using LangGraph – then ship them as FastAPI services with streaming, persistence and proper tests.
• : Own answer quality. Build evaluation datasets, regression suites and LLM-as-judge checks so changes don’t regress user experience.
• : Get the right context to the model by querying our search platform, orchestrating multi-step research loops and shaping context.
• : Debug production: instrument flows with tracing, manage latency and cost budgets, and route across model sizes behind an AI gateway.
