About Serotiny

Inspired by life – Serotiny digitally encodes nature’s features and functions into a biologically aware API for the high-throughput, rational design of multi-domain synthetic proteins.

By coupling state-of-the-art mammalian synthetic biology and a finely-tuned software architecture, Serotiny aims to embrace one of the greatest opportunities of the 21st century to improve people’s lives. Serotiny designs custom proteins with cutting edge capabilities including treatment of cancers and genetic disorders. We partner with leaders in the life sciences to give proteins wholly new functions for more effective, safer, and customized therapies.

With support from world-class investors including Nanodimension and 8VC, Serotiny is proud to build a cross-disciplinary team of passionate individuals with varied experiences.

Mammalian Synthetic Biology - Immunology
San Francisco, CA, Full Time


This person will lead Serotiny’s capabilities for immunology by inventing novel synthetic proteins and collaborating with software developers to deploy creative protein design methodologies.

The infrastructure is part of a design/build/test loop that couples a finely tuned software architecture with wet-lab mammalian synthetic biology. Serotiny is looking for our first synthetic biologist who is excited to utilize Serotiny’s novel software architecture to invent CAR-T systems for immunotherapies.
