AI Engineer

We build production AI systems for SMEs and scaling businesses - not demos, not proof-of-concepts that never ship. Agents that run in real workflows, RAG pipelines with actual retrieval quality, LLM integrations that hold up under load. We also use the same tools internally: our own coding assistants, evaluation harnesses, and automation pipelines. You would own both sides of that work. The work Design and ship AI features into client products: agents, RAG, structured extraction, workflow automationBuild and maintain RBB LAB's internal AI tooling and evaluation infrastructureEvaluate models, prompting strategies, and architectures against real production requirements - not benchmarksWork directly with clients to understand the problem before touching the stackKeep up with the field without chasing every new release What we need Production experience shipping LLM-based systems - something running, not something demoedStrong fundamentals in at least one backend language (we mostly use Go and Rust, Python is fine for ML-adjacent work)A working understanding of retrieval, embeddings, and context engineering - not just API wrappersComfort working in a small team where you own the decision, not just the implementationBased in San Marino or willing to relocate The setup Small team, senior-only.
