Qualifikationen

• Strong software engineering skills with production systems experience.
• Practical experience with LLMs, agents, or retrieval systems.
• Proficiency in Python; familiarity with backend/data infrastructure.
• Solid understanding of embeddings, vector search, retrieval-augmented generation, evaluation, and prompting.

Aufgaben

• Design and build memory systems for AI agents.
• Improve retrieval, ranking, context assembly, and long-term memory.
• Develop systems for entity resolution, temporal reasoning, provenance, and knowledge representation.
• Build agent capabilities that combine reasoning with reliable tool use.
• Design evaluations for retrieval quality, agent behavior, and end-to-end task performance.
• Investigate failures using traces, datasets, and production feedback.
• Experiment with semantic search, graph-based retrieval, reranking, trajectory analysis, and selective replay.
• Ensure agents retrieve and use information according to user permissions and access controls.
• Improve reliability, latency, and cost of AI systems in production.
• Collaborate with founders and engineering team on product direction and architecture.
