About the role

  • Company Summary Alpha-9 Oncology is a clinical-stage biotechnology company pioneering radiopharmaceutical innovation for solid tumors.
  • Our proprietary scaffolds, composed of optimized binders, linkers, chelators, and radioisotopes, enable targeted radiation delivery to cancer cells, minimizing harm to surrounding healthy tissue.
  • More about Alpha-9 Oncology Alpha-9 Oncology is committed to fostering a diverse and inclusive workplace and is proud to be an Equal Opportunity Employer.

Responsibilities

  • Reporting into Clinical Development, this role serves as the internal scientific lead for dosimetry methodology and imaging quantification, ensuring rigor, consistency, and interpretability across multiple active studies.
  • You will define and own how clinical dosimetry is performed at Alpha-9 and ensure it is fully integrated into trial design, dose escalation strategy, and regulatory decision-making.
  • This role operates at the intersection of clinical development, clinical pharmacology, regulatory affairs, and external imaging partners, with direct influence on how quantitative radiopharmaceutical data is translated into clinical decisions.
  • Lead clinical dosimetry strategy across Alpha-9's radiopharmaceutical programs, defining standards for absorbed dose calculation, time-activity modeling, and interpretation across early-phase clinical studies.
  • Integrate dosimetry into clinical trial design and regulatory submissions, including protocols, amendments, investigator brochures, clinical study reports, and IND/CTA documentation.
  • Partner closely with Clinical Development, Clinical Pharmacology, Biostatistics, and Clinical Operations to ensure dosimetry is embedded in dose selection strategy and study execution.
  • Manage external imaging and dosimetry vendors and core laboratories, ensuring methodological consistency, data quality, and timely delivery across active programs.
  • Support regulatory interactions and scientific communications, including responses to agencies, investigator meetings, abstracts, manuscripts, and conference presentations.
  • Focusing on innovative targeting moieties, we develop molecules tailored for precise tumor targeting.

Nice to have

  • Establish and govern quantitative imaging standards for SPECT/CT and PET/CT, including acquisition protocols, reconstruction parameters, QC frameworks, and site qualification criteria.
  • Serve as the internal authority on dosimetry, translating patient- and program-level dose data into actionable insights that inform dose escalation, safety evaluation, and clinical decision-making.
  • Direct experience in radiopharmaceutical or radioligand therapy clinical programs required.
  • Proven experience with quantitative SPECT/CT and PET/CT imaging workflows in clinical trial settings.
  • Strong understanding of internal dosimetry principles (e.g., MIRD methodology) and organ/tumor absorbed dose modeling.
  • Experience contributing to or supporting IND/CTA submissions and regulatory interactions involving imaging or dosimetry.
  • Demonstrated ability to translate quantitative radiopharmaceutical data into clinical development decisions.
  • Experience operating in cross-functional drug development teams, ideally across multiple concurrent clinical programs.

Benefits

  • Alpha-9 Oncology is seeking a Medical Physicist to lead clinical dosimetry and quantitative imaging across our radiopharmaceutical clinical programs.
  • PhD or MS in Medical Physics, Radiation Physics, Nuclear Medicine Physics, or related discipline (Ph.D. preferred).
  • 6-10+ years of experience in radiopharmaceutical development, molecular imaging, or medical physics within oncology drug development.
  • With a robust pipeline entering clinical trials and strong support from leading healthcare investors, Alpha-9 is positioned for rapid growth and advancement in cancer therapy.
