Position Summary The Head, Radiopharmaceutical Diagnostic Development will provide strategic and operational leadership for RayzeBio's diagnostic and companion imaging radiopharmaceutical portfolio, including PET and SPECT imaging agents used for patient selection, dosimetry, and disease monitoring across RayzeBio's radioligand therapy (RLT) programs (e.g., RYZ101, RYZ701, and the broader RYZ-series pipeline). This role owns the diagnostic development strategy end to end — from candidate nomination and CMC development through tech transfer, clinical supply, regulatory submission, and health authority approval — and partners closely with CMC, Quality, Regulatory Affairs, Clinical Development, Manufacturing, Isotope Supply Chain, and Commercial to ensure diagnostic agents are delivered on time, in compliance, and aligned to the needs of each therapeutic program. The role is global in scope: it is accountable for building and executing global development plans across the United States, Canada, the European Union, Australia/New Zealand, and the Asia-Pacific region, and for the ongoing lifecycle management of approved diagnostic products across all markets in which RayzeBio operates.

Job Responsibilities

• Define and own the diagnostic and companion imaging development strategy across RayzeBio's portfolio, aligning imaging agent timelines with the therapeutic programs they support. • Build and execute global development plans for diagnostic radiopharmaceuticals, coordinating regulatory strategy, filings, and market entry across the United States, Canada, the European Union, Australia/New Zealand, and the Asia-Pacific region. • Own lifecycle management for approved diagnostic products, including post-approval changes, label updates, supplemental filings, manufacturing changes, and continued market compliance across all regions in which the products are marketed. • Tailor regional regulatory and CMC strategies to align with local health authority requirements (e.g., FDA, Health Canada, EMA, TGA, and APAC regulatory bodies) while maintaining a unified global development plan. • Lead CMC strategy, process development, and validation for diagnostic radiopharmaceuticals, including radiosynthesis, radiolabeling, and quality control methods for isotopes such as Ga-68, F-18, and Cu-64. • Direct technology transfer and scale-up of diagnostic manufacturing processes across internal sites and third-party CDMOs/CROs, ensuring robust, reproducible, and inspection-ready operations. • Serve as the primary strategic point of contact with FDA and other health authorities for diagnostic imaging agent submissions, meetings, and inspections, including IND, NDA, and ANDA filings. • Author and oversee CMC sections, briefing documents, and regulatory correspondence for diagnostic development programs; lead health authority interactions in partnership with Regulatory Affairs. • Partner with Clinical Development and Translational Medicine to design imaging strategies that support patient selection, dosimetry, and biomarker objectives for RLT clinical trials. • Build, mentor, and lead a high-performing team of scientists and CMC/regulatory professionals supporting diagnostic development. • Ensure diagnostic development activities comply with 21 CFR Parts 211 and 212, USP , NRC requirements, and other applicable radiopharmaceutical regulations. • Manage external supplier, CDMO, and CRO relationships supporting diagnostic manufacturing, analytical testing, and clinical supply. • Represent RayzeBio externally with industry and standards bodies (e.g., SNMMI, MITA, USP) to help shape evolving standards for diagnostic radiopharmaceuticals. • Own budget, resourcing, and risk mitigation planning for the diagnostic development function; report progress and risks to senior leadership. • Identify opportunities to apply digital tools and AI to improve development speed, data integrity, and decision-making across diagnostic programs. • Willing to travel approximately 20–30% of the time; occasional evening or weekend work may be required to support inspections or health authority interactions.

Education and Experience

• PharmD, PhD, or other advanced scientific degree, with 10+ years of experience in radiopharmaceutical, PET/SPECT diagnostic, or nuclear medicine product development, or an equivalent combination of education and experience. • Demonstrated success leading CMC and regulatory strategy for diagnostic or companion imaging radiopharmaceuticals through IND-enabling activities and NDA/ANDA approval. • Hands-on experience with cGMP radiopharmaceutical manufacturing, including cyclotron- or generator-produced isotopes and automated radiosynthesis platforms. • Track record of leading successful FDA inspections (including pre-approval inspections) and direct health authority interactions. • Prior people-leadership experience managing cross-functional scientific, regulatory, and/or quality teams. • Experience building and executing global development and regulatory plans across multiple regions (e.g., US, Canada, EU, Australia/New Zealand, APAC), including lifecycle management of approved products. • Deep subject-matter expertise in PET/SPECT diagnostic radiopharmaceutical development, manufacturing, and regulatory
