## About the role

We're seeking a Senior Data Scientist to build the voice AI and model capabilities behind Tom, our AI-enabled primary care platform. Reporting directly to our VP of AI, you'll split your time between two halves of the same problem: developing and fine-tuning the models that power clinical AI, and building the voice systems that let us test, stress, and trust those models before they ever reach a patient.

## What they're looking for

- Bachelor's degree with quantitative major (e.g. statistics, mathematics, economics, and actuarial science) or equivalent
- 5+ year of relevant data science, machine learning, or applied AI experience, or the knowledge, skills, and abilities to succeed in the role
- Must-have hands-on experience building and deploying production voice or conversational AI systems — speech and speech-to-speech, working with real audio in live environments, not text-only NLP or chat
- Must-have demonstrated experience training neural networks from scratch and fine-tuning language models, with the ability to explain different training approaches and when each applies
- Proven track record of shipping, scaling, and hardening AI systems in production
- Strong programming skills in Python and fluency with modern deep learning frameworks (PyTorch, TensorFlow)
