Data Scientist (AI Quality & Evaluation)
Bioscope AI · Boston
About the Role
We're looking for a Data Scientist to own the quality, reliability, and trustworthiness of our clinical AI outputs. You'll build the systems that ensure our AI "knows what it doesn't know" — developing evaluation frameworks, calibrated confidence scoring, and automated quality assurance that physicians can actually trust.
What You'll Do
Design and implement automated evaluation pipelines that assess AI output quality, accuracy, and safety at scale
Develop uncertainty quantification systems where confidence scores meaningfully correlate with accuracy
Build comprehensive evaluation frameworks combining automated assessment with clinician-validated test cases
Implement feedback loops that continuously improve model outputs based on validation signals
Establish scalable quality gates that catch errors before they reach end users
Contribute to model alignment and fine-tuning efforts
Qualifications
Required
Strong foundation in deep learning frameworks (PyTorch) and LLM architectures
Experience with model evaluation, benchmarking, and quality metrics
Proficiency in Python and modern ML development tools
Strong statistical foundations
Ability to read, implement, and extend research papers
Excellent communication skills
Preferred
Master's degree in Computer Science, Machine Learning, Statistics, or related quantitative field (PhD preferred)
Publications in top ML/AI venues (NeurIPS, ICML, ICLR, ACL)
Experience with RLHF, DPO, or preference optimization techniques
Background in healthcare AI or regulated industries
Experience building evaluation systems for production LLM applications
