Process Validation & Qualification:

• Lead or support validation and qualification activities for radioisotope production processes in accordance with 21 CFR 211.100 and 211.110 requirements for process validation and in-process controls
• Develop and execute validation protocols for equipment, manufacturing processes, and analytical methods
• Support qualification of production equipment, hot-cell systems, and laboratory instrumentation used in isotope processing
• Generate and review validation reports to ensure compliance with regulatory expectations
• Provide quality input into the preparation and maintenance of Drug Master Files (DMFs) and other regulatory submissions associated with radioisotope production and supply

Drug Master Files (DMF) Support:

• Provide quality input into the preparation and maintenance of Drug Master Files (DMFs) and other regulatory submissions associated with radioisotope production and supply

Risk Management & Investigations:

• Conduct risk assessments and hazard analyses to support development and production activities involving radioactive materials
• Investigate deviations, nonconformances, and out-of-specification events related to radioisotope production processes
• Perform root cause analysis and implement corrective and preventive actions (CAPA) to maintain compliance and product quality

Cross-functional Collaboration:

• Work closely with radiochemistry and cyclotron operations teams to support development and scale-up of new isotope production processes
• Provide quality oversight during technology transfer from research and development to commercial production
• Support continuous improvement initiatives related to process robustness, compliance, and operational efficiency

Qualifications & Skills

Education:

• Bachelor’s degree in chemistry, Chemical Engineering, Biomedical Engineering, Radiochemistry, Pharmaceutical Sciences, Biological Sciences, or related field

Experience:

• A Minimum of 5 years of experience in quality engineering, quality assurance, or validation within regulated environments
• Experience working with radioisotope production, radiochemistry, pharmaceutical manufacturing, or nuclear materials strongly preferred
• Experience supporting Drug Master File (DMF) submissions or pharmaceutical regulatory filings preferred
• Experience supporting process validation, equipment qualification, and GMP documentation

Knowledge & Skills:

• Strong knowledge of cGMP and regulated quality systems (FDA, ISO, pharmaceutical, or medical device)
