Staff ML Research Scientist

Staff ML Research Scientist

We9re looking for a Staff Machine Learning Research Scientist to help define and drive Rad AI9s next generation of applied research in NLP and clinical AI.

We work across LLMs, retrieval, representation learning, speech and multimodal modeling, and we care as much about evaluation and reliability as we do about state-of-the-art results. You will have scope, ownership, and a direct line from research to product.

You9ll collaborate closely with clinicians, engineers, and product leaders to translate foundational research into production-scale systems that improve outcomes for doctors and patients alike. As we grow, you will help shape standards for model quality, safety, and observability, and contribute to strategic initiatives that include computer vision and vision-language work.

What You9ll Do:

• Own end-to-end applied research: frame the problem, design experiments, ship to production, and monitor impact against real-world metrics.
• Set technical direction across LLMs, retrieval, and multimodal; run ablations/error analysis that change product decisions.
• Build evaluation that matters: link offline metrics to online outcomes; define thresholds, monitoring, and rollback.
• Partner to deliver with engineering and product-and, when relevant, clinicians/domain experts-to align data, success criteria, and timelines.
• Raise the bar by mentoring peers and codifying standards for reliability, safety, and documentation.
• Improve the platform (data, training, serving, observability) to speed iteration and ensure reproducibility.
• Explore new directions, with computer vision/vision-language work as a nice-to-have for future strategic initiatives.

What We9re Looking For:

• MS or PhD (or equivalent research experience) in Computer Science, Electrical Engineering, Computational Linguistics, Biomedical Informatics, or related quantitative field.
• 7+ years of applied ML research experience (or PhD + 5 years, or equivalent evidence of Staff-level impact).
• Depth in one or more areas: LLMs and NLP, computer vision, speech, recommendation/ranking, retrieval, or multimodal modeling.
• Strong experimental rigor: clear hypothesis framing, offline10online linkage, calibration and stratified analyses, ablations that influence decisions.
• Proven ability to take models to production
• Hands-on with modern tooling: PyTorch and common experiment/ops tools (for example MLflow, Databricks, Ray, or similar).
• System thinking: can choose methods based on constraints, design for observability and rollback, and document decisions clearly.
• Collaborative communicator who writes crisp design docs and explains complex ideas to non-specialists; comfortable mentoring peers.

Preferred Qualifications

• Health data familiarity, including EHR or imaging
• Experience in one or more areas: clinical NLP or LLMs, computer vision, speech, retrieval or multimodal modeling.
• Shipped, measured models in production with monitoring and clear rollback; external or multi-site validation is a plus.
• Workflow integration with EHR, RIS, PACS, or reporting systems; PowerScribe or Dragon exposure helpful.
• Strong evaluation practices: calibration, slice analysis, and ablations
• Safety and governance in sensitive domains, including PHI handling and HIPAA or FDA-adjacent environments.
• Technical mentorship and contributions to team research culture; publications or impactful open-source work.
• Practical tooling: PyTorch plus modern ML ops tools such as MLflow, Databricks, Ray, or Triton.

Why This Matters:

Radiologists are the invisible backbone of modern medicine. Every diagnosis, every surgery, every treatment plan begins with their interpretations. Yet they9re often overwhelmed by cognitive load, repetitive tasks, and administrative overhead.

At Rad AI, we9re using ML to change that-building intelligent systems that understand medical context, streamline documentation, and amplify human expertise.

You9ve already seen how AI can transform healthcare. Now help us push it further. Join us in shaping how AI supports the next generation of medical professionals.

Join our world-class team as we build and deploy AI solutions that empower physicians and transform patient care-making a meaningful impact on millions of lives. Driven by our mission, we prioritize transparency, inclusion, and close collaboration, bringing together exceptional people to revolutionize healthcare. If you9re passionate about driving innovation and delivering impactful healthcare solutions, we9d love to hear from you!
