> Own applied multimodal ML research from clinical problem definition through production, developing and rigorously evaluating computer vision, NLP, and deep learning systems for radiology. Requires strong Python and PyTorch expertise, 4+ years of relevant experience, and an MS, PhD, or equivalent practical experience.

## Job Description

## Responsibilities
- Own multimodal machine learning workstreams from problem definition through experimentation, evaluation, deployment, and iteration.
- Translate clinical and product needs into ML objectives, data strategies, model approaches, and success criteria.
- Build and evaluate ML systems using transformers, self-supervised learning, weak supervision, detection, localization, and segmentation.
- Develop systems from image, report, and other clinical data for real radiology workflows.
- Design rigorous evaluations covering clinically meaningful operating points, robustness, calibration, and performance across relevant data slices.
- Partner with engineering to productionize models, make practical system tradeoffs, and assess performance after launch.
- Investigate failure modes including laterality errors, poor image or report grounding, hallucination, dataset bias, domain shift, and workflow disruption.
- Communicate research findings and technical decisions through design documents, experiment reviews, and presentations.
- Contribute to the research roadmap and mentor researchers and engineers.

## Requirements
- Strong applied experience in computer vision, NLP, or deep learning, including independently designing experiments, analyzing results, and turning findings into working systems.
- Experience owning substantial ML projects across data, modeling, and production delivery.
- Strong hands-on Python and PyTorch skills, with sound judgment regarding model architecture, data quality, experimentation, and evaluation.
- Experience with modern vision or multimodal techniques such as vision transformers, contrastive learning, masked image modeling, or weak supervision.
- Ability to connect model performance to user and clinical outcomes.
- Strong collaboration and communication skills across research, engineering, product, data, and clinical teams.
- Typically 4+ years of relevant applied ML research or engineering experience, or equivalent scope and impact.
- MS, PhD, or equivalent practical experience in Computer Science, Electrical Engineering, Machine Learning, Biomedical Engineering, or a related quantitative field.

## Nice to Have
- Medical imaging, radiology, healthcare, or other high-stakes application experience.
- Familiarity with chest X-ray, CT, MRI, mammography, or other clinical imaging modalities.
- Experience with DICOM, image-report pairing, medical data de-identification, radiology workflows, or clinically derived labels.
- Experience evaluating models across patients, sites, scanner vendors, protocols, or other distribution-shift sources.
- Familiarity with clinical validation, FDA or HIPAA considerations, or regulated and privacy-sensitive environments.
- Experience with 3D vision, longitudinal imaging, report generation, or clinical decision support.
- Publications, open-source contributions, or other evidence of research credibility.

## Compensation and Benefits
- Salary: $170,000–$220,000 annually.
- Medical, dental, vision, and life insurance.
- HSA with employer match, FSA, and DCFSA.
- 401(k), 11 paid company holidays, flexible PTO, annual company-wide and periodic team offsites, and an annual equipment stipend.
