Responsibilities

• Design, build, and maintain LLM-based agent workflows, including multi-step reasoning, tool/function calling, and human-in-the-loop approval steps.
• Evaluate and tune LLM usage across multiple providers and model tiers to balance accuracy, latency, and cost for different task types.
• Build and improve retrieval-augmented generation (RAG) pipelines: document processing, chunking, embeddings, and vector search.
• Develop and refine knowledge and memory systems that let the assistant learn from and retrieve domain-specific technical content over time.
• Design prompts, structured tool schemas, and evaluation frameworks to measure and improve agent accuracy and reliability.
• Add observability for LLM and agent behavior — tracing, quality metrics, and regression detection.
• Collaborate with backend engineers to integrate ML components into a production Python service, including data storage and asynchronous processing.
• Run structured experiments on models, prompts, and retrieval strategies, and translate results into shipped improvements.
• Participate in code review, automated testing, and production debugging for ML and agentorchestration code.

Qualifications

• Master's degree in Computer Science, Machine Learning, Electrical Engineering, or a related field.
• 2–4+ years of experience building production ML, NLP, or LLM-powered systems.
• Strong Python skills, including experience with asynchronous programming and typed data modeling.
• Hands-on experience with LLM application development: prompt engineering, tool/function calling, structured output, and output evaluation.
• Familiarity with vector databases and embedding-based retrieval.
• Understanding of agent orchestration concepts (multi-step reasoning, tool use, state management), or the ability to learn them quickly.
• Working knowledge of relational databases and caching layers.
• Comfort working in a fast-moving, iterative R&D environment with evolving requirements.
