About Us
At Sully.ai, We’re Building the Most Impactful Healthcare Company on Earth

We believe that access to a great doctor is a basic human right. Today, that’s not a reality. Delays, misdiagnoses, administrative chaos, and burnout plague the system.

Our Mission
One Human, One Doctor.
We enable our customers to staff 30% of their workforce with AI by creating a shared agent architecture for scale and efficiency. All powered by our own patented, world-class models and deployed in real-world care.

Key Responsibilities

• Build and scale automated evaluation pipelines (LLM-as-judge + human review) with clinical-grade benchmarks.

Hard Requirements

• Proven experience designing agentic processes and LLM evaluation/benchmarking frameworks.

• Strong Python and ML background (PyTorch/TensorFlow, Hugging Face, LangChain/LlamaIndex).

• Demonstrated ability to design rigorous experiments and translate findings into production.

• Track record of published research or deep applied work in LLMs and agent evaluation.

• Strong communication and technical writing skills to articulate complex findings clearly.

• First-Month Focus

• Audit existing evaluation approaches for clinical and agentic tasks.

• Define initial benchmarks and build early automated pipelines.

• Partner with engineering to land first set of CI gates for accuracy, factuality, and safety.

• 90 Days

• Deliver a repeatable evaluation framework with automated pipelines in production.

• Demonstrate measurable improvements in robustness, hallucination reduction, or safety.

• Publish or present internal research findings that directly shape product reliability.

• If you’ve ever said, “I want to do work that actually matters”, this is it. Let’s build something life-changing, together.
