Catalyst Labs' client is reimagining how knowledge is shared by building interactive digital minds that people can talk to, learn from, and be guided by, and they need an Applied AI Engineer to help architect the foundation of next-generation Mind Architecture
Requirements
- 4-6 years of experience in AI or ML engineering, with at least 2 years hands-on with LLMs in production
- Proven track record of building and deploying ML-powered systems that directly impact end-user experience
- Strong Python expertise, including asynchronous programming, event loop optimization, and performance tuning
- Experience with retrieval-augmented generation (RAG), context engineering, and LLM eval frameworks
- Deep practical understanding of how LLMs reason, how to structure inputs, and how to measure improvement
- Experience with graph databases or graph-based retrieval (Neo4j, ArangoDB, or custom-built graph layers)
- Background in document understanding, embeddings, or multimodal context assembly
Responsibilities
- Design and evolve the graph-based architecture that models a mind's reasoning, associations, and conceptual hierarchies
- Develop novel embeddings and contextual retrieval methods that make each mind distinct not just accurate, but alive
- Build next-generation retrieval-augmented generation systems that integrate structured graph reasoning with neural retrieval
- Implement and refine LLM evaluation frameworks to ensure each mind improves over time in quality, consistency, and individuality
- Push the performance of frontier LLMs through advanced prompt engineering, dynamic context shaping, and evaluation-driven iteration
- Architect efficient, low-latency inference pipelines for thousands of simultaneous mind interactions
- Bridge ML systems and product engineering shipping AI-powered features that shape user experience directly
