The Position

2026 Summer Intern - Radiochemistry/Organic Chemistry (Department of Translational Imaging)

Department Summary

The Translational Imaging department accelerates drug discovery and development by developing non-invasive imaging strategies to visualize biodistribution and target engagement in vivo. Our team integrates chemistry, biology, and physics to design novel imaging agents and methodologies across multiple modalities, including MRI, Optical, CT, PET, and SPECT. We are dedicated to creating advanced chemical tools and imaging solutions that provide critical insights into disease biology and therapeutic efficacy.

This internship position is located in South San Francisco, on-site.

The Opportunity

• Synthesize and characterize novel small molecule precursors and standards (specifically bioorthogonal handles) for CNS imaging applications.

• Perform bioconjugation workflows to attach chemical handles to antibody fragments (VHH) and conduct rigorous purification.

• Evaluate the stability and reaction kinetics of imaging probes in complex biological environments.

• Gain experience with radiochemistry optimization and the development of pretargeting systems (e.g., TCO-Tetrazine).

• Apply critical thinking to troubleshoot synthetic routes and assay designs.

• Contribute to Genentech’s culture of scientific curiosity and discovery via cross-department presentations.

Program Highlights

• Intensive 12-weeks, full-time (40 hours per week) paid internship.

• Program start dates are May/June, 2026.

• A stipend, based on location, will be provided to help alleviate costs associated with the internship.

• Ownership of a challenging and impactful project.

• Work with some of the most talented people in the biotechnology industry.
