• Design prompts, system messages, and model workflows, and iterate based on data and user feedback.


• Implement LLM agent based workflows, including tool calling, retrieval, and multi step task orchestration.


• Set up evaluation, logging, quality metrics, latency and cost monitoring for LLM based features.


• Work with engineering teams to identify where AI brings the biggest value and improve their workflows.

Requirements

• Strong programming skills in Python, TypeScript, or similar.


• Experience building software that uses LLM or generative AI APIs.


• Hands on experience using AI coding assistants like GitHub Copilot, Cursor, Claude Code, or similar.


• Understanding of LLM fundamentals, for example tokenization, context limits, temperature, prompt structure.


• Experience with RAG, agents, or function calling in production.


• Ability to design experiments and measure impact on quality, cost, and performance.


• Good communication skills and ability to work with cross functional teams.
