Location requirements - United States Mercor is hiring fellowship-trained breast imaging radiologists (MDs and DOs) to help build rigorous evaluations of how well AI reads real imaging studies, in partnership with a leading AI lab. This is not image labeling. You will read de-identified studies, write the reference finding or report, and review AI-drafted reads to mark what is inaccurate, unsupported, or unsafe. Your clinical judgment becomes the reference standard that trains and tests frontier models, work that improves outcomes for millions of patients around the world. Key Responsibilities Read de-identified screening and diagnostic mammography, tomosynthesis, breast ultrasound and breast MRI studies and record the reference finding Apply the structured systems and measurement conventions you use in practice (BI-RADS and related standards) Review AI-generated reads and flag errors that are inaccurate, unsupported, or could compromise patient safety Write structured rationales on clinical rigor, completeness and clarity Required Qualifications MD or DO from a medical school in the United States Board certified in ABR Diagnostic Radiology through an ABMS member board or the AOA Completed a breast imaging or women's imaging fellowship Active, unrestricted US medical license Currently practicing and reading breast imaging in the US, with at least 5 years of independent practice after training Resident in the US, outside California Clear written communication and close attention to detail Project Details Remote and hourly, with flexible part-time hours Start date: immediate Application & Onboarding Upload your resume Complete a 25-minute conversational interview on your background, experience and motivations Credential verification: license status, board certification, training and current practice setting Receive next steps and onboarding details within a few days Apply today and put your clinical expertise to work shaping the imaging models clinicians and patients will rely on. We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request. Contract and Payment Terms You will be engaged as an independent contractor. This is a fully remote role that can be completed on your own schedule. Projects can be extended, shortened, or concluded early depending on needs and performance.

Location requirements - United States Help define how frontier AI models reason about mathematics. 1. Overview We are looking for senior mathematicians to improve how frontier AI models reason about real mathematical research. Your mathematical judgment is the substance of this role. You will review the quality of mathematical reasoning tasks and model outputs, write the problem specifications and reference solutions and proofs that define what "correct" looks like, and design benchmarks that show whether a model is genuinely improving. We are looking for a practicing specialist rather than a generalist. This role is fully remote. 2. Key Responsibilities Expert review: Assess mathematical tasks and model outputs, catching gaps in proofs, unjustified steps, incorrect generalizations, and arguments that read well but would not survive peer review. Problem specs and reference solutions: Write precise problem statements and rigorous reference solutions and proofs that reflect how research mathematics is actually done. Benchmarks: Design challenging, research-level problems and evaluation sets in your area of specialization. Calibration: Work with other researchers and experts in adjacent fields to turn tacit expert judgment into explicit, teachable criteria. 3. Core Qualifications Education: PhD in mathematics, applied mathematics, statistics, operations research, or a closely related field. Seniority: A faculty appointment, principal investigator, staff or senior scientist, or an equivalent senior research role at a university, national laboratory, or research organization. Domain depth: Genuine specialization in at least one area, for example analysis and PDE, algebra and number theory, geometry and topology, probability and statistics, or applied mathematics and optimization. Research record: A strong peer-reviewed publication record. Recognition such as competitive fellowships or awards is a plus. AI fluency: Hands-on use of large language models in your work, and the judgment to tell a sound argument from a plausible-sounding wrong one. Communication: Excellent written communication and the ability to give precise, well-structured feedback. Location: Based in the United States. We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
