Senior Director, Dosimetry and Radiobiology Physicist
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). Include a section only when posting has real, specific content. We need to preserve all substantive info, remove boilerplate, navigation, legal, EEO, etc. Also remove duplicated lines, application instructions. We need to include sections: maybe "About the role" (the description of role), "Responsibilities", "Qualifications" (basic and preferred), "Skills", "Benefits", "Pay". Also maybe "Work Environment" but not in list; we can include if content but not required headings. The instruction says prefer a few substantive sections over many thin ones. So we can combine some.
We need to output only HTML fragment, no /, no markdown fences.
We need to use for each section heading. Use - for any list of duties/requirements/benefits. Use
for prose.
We must not repeat job title as heading. The job title is "Sr. Director, Radiopharmaceutical Dosimetry & Radiobiology". Not to be used as heading.
We need to preserve all substantive info: include description of role, responsibilities list, qualifications (basic and preferred), skills list, benefits, pay ranges. Also maybe mention remote vs location pay.
We need to remove boilerplate: "Life at BMS At RayzeBio..." maybe considered "About the role" or "About the company". We'll keep that as a paragraph under "About the role". Also "Learn more about RayzeBio: https://careers.bms.com/rayzebio/" maybe we can keep as link? It's substantive? It's a link; we can keep as part of paragraph.
We need to remove duplicated lines, cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate. So remove sections like "Supporting People With Disabilities", "Candidate Rights", etc. Also remove "Physical Demands", "Work Environment"? Those are substantive but not in heading list; we could include them under a generic section like "Work Environment" but not required. The instruction says prefer a few substantive sections over many thin ones. Could combine Physical Demands and Work Environment into a "Working Conditions" section but not in list. Safer to omit if not required headings? The instruction: "Use
for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It gives examples but not exclusive; we could add other headings if needed. But better to stick to those examples. We have content for About the role, Responsibilities, Qualifications (basic and preferred), Skills, Benefits, Pay. Schedule not present. So we will output those sections.
We need to ensure we don't include placeholder text like "commensurate with experience". Not present.
We need to preserve all substantive info: include details about responsibilities (list). Include basic qualifications, preferred qualifications. Include skills list (maybe combine with qualifications? But we have separate Skills section). The posting has "Skills And Qualification" heading with a paragraph of skills. We'll treat that as Skills section.
We need to include Pay section with the compensation overview: remote US range, San Diego range, plus note about discretionary incentive cash and stock.
Benefits section: include description of benefits.
We need to remove duplicated lines: there may be duplicate sentences; we need to check.
Let's extract content.
First paragraph: "Life at BMS At RayzeBio, every day is an opportunity to ignite meaningful change. As a wholly-owned subsidiary of Bristol Myers Squibb, RayzeBio blends the nimble, pioneering spirit of an emergent biotech with the global expertise and resources of a leading innovator in oncology.

Then "Skills And Qualification" paragraph (looks like a list of skills but in prose). We'll treat as Skills section with
- items maybe. The paragraph includes many items separated by commas and semicolons. We could split into list items for clarity. But we need to preserve all substantive info; we can keep as
but the instruction says use
- for any list of duties/requirements/benefits. Skills is a list, so we should use
- . We'll parse the skills into items.
Skills paragraph:
