About The Position

Telix Pharmaceuticals is a dynamic, fast-growing radiopharmaceutical company with offices in Australia (HQ), Belgium, Japan, Switzerland, and the United States. Our mission is to deliver on the promise of precision medicine through targeted radiation. At our core, we exist to create products that seek to improve the quality of life for people living with cancer and rare diseases. You will be supporting the international roll-out of our approved prostate cancer imaging agent and helping us to advance our portfolio of late clinical-stage products that address significant unmet need in oncology and rare diseases. Physical Sciences R&D is seeking a Senior Scientist with deep expertise in organic, analytical, and radiochemistry to play a critical role in the design, development, and advancement of radiopharmaceutical programs across the Telix pipeline. In this role, the Senior Scientist will independently lead complex experimental workstreams, contribute to program‑level scientific strategy, and solve technically ambiguous problems spanning discovery through GMP‑adjacent development. The position requires regular handling of radioactive materials and work within both R&D and GMP environments. The ideal candidate is a recognized technical expert who operates with minimal supervision, mentors junior scientists, and is motivated to make high‑impact contributions to the next generation of radiopharmaceutical therapeutics.

Requirements

PhD + 5 years, MS + 6 years, or BS + 8 years of relevant industry or post‑doctoral experience.
Demonstrated experience working with radioactive materials in an R&D and/or GMP‑adjacent environment.
Proven track record of independent scientific contribution and problem solving.
Advanced proficiency in synthetic organic chemistry and radiochemistry.
Strong experience developing and applying radioanalytical methods (e.g., radio‑TLC, HPLC).
Expertise in statistical experimental design, data interpretation, and structured problem solving (e.g., Six Sigma methodologies).
Experience leading project‑level or workstream‑level scientific initiatives.
Strong written and verbal communication skills, with the ability to clearly convey complex technical concepts.
Demonstrated ability to influence without authority and operate effectively in a matrixed, fast‑paced environment.
