Chip Characterization Engineer

Palo Alto, California

Company Description

Quantum-Si is pioneering a new generation of technology to create the market of Next Generation Protein Sequencing (NGPS). Similar to Next Generation DNA Sequencing (NGS), which gave us a blueprint of what could happen by studying our DNA, NGPS enables an unbiased view of the proteome through improved scale, resolution, and sensitivity leading to better understanding of disease and improved general health. 

We operate at the intersection of biochemistry, chemistry, hardware, molecular biology, photonics, semiconductor chips, and software with a goal to drive a digital transformation of a $44 billion dollar proteomics market.


Join us on the journey to transform healthcare, motivated by the idea that the products you work on will change the lives of millions of people around the world.
