  • Excellent collaboration and communication skills, capable of articulating complex technical ideas clearly and effectively.
Responsibilities
  • Develop scalable MLIP frameworks capable of representing diverse chemical systems with high fidelity.
  • Innovate and implement state-of-the-art machine learning models, such as graph neural networks, equivariant architectures, or hybrid approaches for interatomic potential development.
  • Curate and integrate large-scale datasets from first-principles calculations (e.g., DFT) and experimental sources.
  • Explore active learning and automated data acquisition workflows for efficient dataset expansion.
  • Address challenges of scalability, generalizability, and transferability in MLIP designs.
  • Optimize training and inference pipelines to leverage high-performance computing resources effectively.
  • Contribute to the AI and materials science research community through publications and active engagement in top-tier AI/ML venues like NeurIPS, ICML, ICLR, and our company blog, alongside active participation in conferences and workshops.
  • Tackle challenging problems with new and different ideas, creativity and contrarian thinking.
  • Mentor and guide junior team members and interns, promoting an environment of continuous learning and innovation.
Desired Qualifications
  • Experience in developing or applying MLIPs such as Gemnet, MACE, NequIP, Allegro, or similar frameworks.
  • Familiarity with software engineering best practices.

Radical AI builds AI-powered software that augments radiologists by fitting into existing clinical workflows. Its core product acts as a clinical workflow orchestrator that triages medical imaging studies (such as CT scans and X-rays) by automatically identifying findings that indicate critical conditions and prioritizing those cases in the radiologist’s worklist, so urgent cases are reviewed first. The company targets hospitals and imaging centers with a B2B licensing or subscription model for its AI tools. What sets Radical AI apart is its emphasis on workflow optimization and diagnostic prioritization grounded in medical imaging expertise from its Duke-affiliated founders, aiming to reduce clinician burnout and shorten the time to diagnosis. The overarching goal is to alleviate the growing gap between imaging demand and the available diagnostic workforce while improving patient outcomes through faster, more efficient readings.
