As an LLM Applications Engineer, you will be the architect of our LLM infrastructure. You won't just be building interfaces; you will be designing the retrieval systems, agentic workflows, and data pipelines that bridge the gap between complex experimental data and actionable AI insights. Your work will directly modernize how the world’s leading researchers interact with their data. Primary Responsibility Your primary responsibility is to design, build, and scale the LLM infrastructure and user-facing AI features of the Uncountable Web Platform. This is a hybrid role requiring a deep understanding of full-stack development and the unique challenges of deploying LLMs in production. - Feature Development: Build intuitive, AI-driven UI components that allow scientists to query, analyze, and visualize complex experimental datasets. - Integration: Connect LLM capabilities with our core SQL databases and data analysis engines to ensure high-fidelity, grounded AI responses. Salary Range: $125K–$160K + Equity Requirements - 2+ years of software development experience with a focus on full-stack web applications. - Proven experience with LLM orchestration frameworks (e.g., LangChain, LlamaIndex, or Haystack). - Proficiency in Python and JavaScript/TypeScript: Ability to work across the AI backend and the React frontend. - Solid Engineering Fundamentals: Experience with API design, asynchronous processing, and performance optimization. Preferred Qualifications - B.S. in Computer Science or a related technical field. - Experience with LLM Evaluation: Knowledge of how to measure and mitigate "hallucinations" in a scientific/technical context. - Familiarity with SQL: Specifically optimizing queries that serve as the context for LLM prompts. - Product Mindset: A passion for creating "LLM-first" user experiences that feel seamless rather than bolted-on.
