About The Position

Nolla is building AI doctors to make top-quality healthcare accessible to everyone.

This role focuses on AI engineering, specifically integrating LLMs and custom models into production systems where accuracy is critical.

• Proven track record of shipping personal projects (side projects, open source, launched apps).
• Experience working on small teams and building products from scratch.
• Familiarity with the AI engineering toolkit: prompts, evals, tool calling, RAG, common LLM APIs, with strong opinions on their application.

• Experience with observability stacks like Langfuse, Sentry, or similar.
• Prior work in clinical AI, digital health, or other regulated domains.

Responsibilities

• Build and maintain backends for existing and new specialty apps, owning systems end-to-end from schema design to production.
• Develop clinician-facing dashboards and tooling for AI output review.
• Create internal tools for clinical operations and physicians.
• Work on prompts, tool calling, and inference optimization for AI features.
• Build evals and observability for AI systems, defining standards for performance.
• Implement abstention, routing, and fallback strategies prioritizing safety and correctness.
• Support a wide range of work including payments, user flows, clinical infrastructure, and model deployment.
• Architect systems to support rapid product expansion into new verticals, states, and clinical modalities.
