Senior/Staff Deep Learning and Signal Processing Scientist

San Diego, 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.

Job Description

We are looking for an experienced and ambitious computational scientist to join our algorithms and data analysis teams with a focus on predictive analytics and signal processing. We have terabytes of data that we add to every day through multiple research programs and some of the hard problems that are posed by our research scientists require computational approaches in signal processing, pattern recognition, and probabilistic modeling to search for answers. This is a unique opportunity for an ambitious data scientist as the data has multiple layers of information that correspond to different scientific or engineering fields. These cover digital signal transduction through cmos chips, organic chemistry, and molecular biology kinetics. The ideal candidate will have a strong background in a computational field with a focus on high resolution time series data analysis and experience with scientific data sets.
