• Build and deploy LLM-based systems, including RAG pipelines, fine-tuned models, and embedding search
• Own delivery of real-world solutions: architect, implement, test, ship
• Iterate rapidly: explore new tools, try new ideas, and solve problems creatively
• Operate with autonomy in a fast-changing environment — sometimes as the only engineer on a project
• Occasionally dive into adjacent areas like frontend, dev tooling, or data pipelines as needed
