Transmutex is a Swiss company founded in 2019, advancing the HI-BEAM (High Intensity Breakthrough Engineering for Advanced Medicine) project to develop an industrial-scale facility for producing medical-grade Actinium-225 (Ac-225), a critical radionuclide for targeted alpha therapies in cancer treatment.
As a Senior Radiochemist, you will contribute to the technical design of Transmutex's radiochemistry process, translating established laboratory methods into automated, reproducible, and commercially viable production processes. You will report to the Head of Extraction unit and work within a small international team spanning nuclear physics, engineering, software, radiochemistry, pharmaceutical, and industrial development.
Key responsibilities include:
**Process Development:**
- Design and optimize radiochemical separation and purification methods
- Collaborate across teams to develop radiochemical processes and methodology
- Perform radiochemical and chemical analyses, including alpha and gamma spectrometry
- Track radiochemistry developments and adopt relevant innovations and best practices
**Industrialization and Operations:**
- Develop the radiochemical process flowsheet, including unit operations, process parameters, material balances, cycle times, and waste streams
- Scale up and transfer laboratory processes to a robust and GMP-compliant production line
- Define process, equipment, utility, instrumentation, and facility-interface requirements
- Support equipment selection, sizing, qualification, commissioning, and process validation
- Develop operating procedures, batch records, control strategies, and consumables requirements
- Prepare laboratory and production operations aligned with capacity and customer needs
- Train and mentor colleagues
**Compliance, Quality, and Safety:**
- Work with QA and Safety to ensure regulatory compliance and meet applicable standards
- Implement and monitor safety protocols and regulatory requirements
You will be primarily based in Vernier, Geneva, with regular travel to Villigen, AG and to partner research labs in North America. The role includes one day per week work from home and five weeks' paid vacation.
**Requirements:**
- PhD or Master's degree in Radiochemistry, Nuclear Chemistry, or related field
- Minimum 10 years of experience in radiochemistry
- Proven experience in radiochemical separation and purification with strong knowledge of actinide chemistry
- In-depth understanding of radiochemistry processes, equipment, and tools
- Mastery of characterization techniques: alpha or gamma spectrometry, ICP-MS, ICP-OES, liquid scintillation counting, or comparable analytical techniques
- Demonstrated knowledge of safety, radioprotection, and GMP regulations and requirements
- Excellent verbal and written communication skills with ability to collaborate effectively across disciplines
- Strong analytical and problem-solving abilities to address complex technical challenges
- Fluent in English; excellent knowledge of French or German is an asset
- Proven experience in translating lab-scale processes to GMP production line is an asset
