Position Summary TerraPower Isotopes is seeking an Analytical Radiochemist to support the analytical characterization, quality control testing, and release of radioisotopes and radiopharmaceutical precursors produced at the Everett facility.

This role is central to ensuring the analytical reliability and regulatory compliance of isotope production operations. The Analytical Radiochemist will contribute to the development, validation, transfer, and execution of analytical methods supporting both process characterization and GMP manufacturing. The successful candidate will work within a multidisciplinary team of scientists, engineers, and quality professionals to generate high-quality analytical data that enables safe production, regulatory compliance, and timely product release.

This position is well suited for analytical scientists who enjoy solving complex measurement challenges, improving analytical robustness, and operating in a mission-driven environment where rigorous science directly supports medical innovation.

Key Responsibilities

Perform analytical testing supporting in-process monitoring, stability studies, and final product batch release. Develop, optimize, and execute analytical methods for radioisotopes and radiopharmaceutical precursors. Participate in method validation, qualification, transfer, and verification activities following ICH Q2 and USP guidance.

Operate analytical techniques including gamma spectroscopy, alpha spectroscopy, ICP-MS/ICP-QQQ-MS, ICP-OES, radio TLC scanning, and liquid scintillation counting. Perform radioactivity calculations including decay corrections and isotopic equilibrium assessments. Calibrate and troubleshoot instrumentation such as HPGe detectors, ICP-MS/OES, alpha spectroscopy systems, and LSC systems.

Generate and review analytical data according to ALCOA+ data integrity principles. Utilize a LIMS compliant with 21 CFR Part 11 to manage analytical data and laboratory records. Support investigations including OOS, OOT, and laboratory deviations.

Contribute to root cause analysis and CAPA implementation. Author and maintain SOPs, analytical methods, validation documents, investigation reports, and other laboratory documentation supporting radioisotope production. Develop and implement analytical procedures, documentation, and laboratory forms relevant to isotope production and quality control activities.

Prepare analytical standards, reagents, and reference materials.
