ClearLight Biotechnologies is an early stage biotech tools company that is developing a 3D tissue analysis platform. We currently provide 3D tissue analysis to our customers (biotech and academic researchers). Our technology is based on the patented CLARITY lipid-clearing technique developed by its founder, Karl Deisseroth MD PhD and licensed from Stanford University. This technique enables the transformation of tissue into a nanoporous, hydrogel-hybridized form that is crosslinked to a three-dimensional network of hydrophilic polymers. The process produces a fully assembled, intact tissue, which is permeable to macromolecules and optically transparent, thus allowing for robust three-dimensional imaging of subcellular components (DNA, RNA and protein) and analysis of heterogeneous cellular interactions within the tissue microenvironment. This technology and platform, paired with proprietary 3D image analysis software, will enable more accurate analysis and assessment of normal and diseased tissue.

Job Title: Research Associate
Location: Sunnyvale, CA 94085

We are hiring research associates who will help develop the technology by analyzing customer tissue samples. This will involve clearing the tissue, immunostaining, imaging with 3D microscopes (confocal or lightsheet) and analysis of the 3D images. You will receive training in our specific technology but general familiarity with microbiology/histology analysis of tissue samples is expected.

The ideal candidate is a self-starter with a desire to work in a fast-paced small startup environment.


  • B.S. in immunology/molecular biology or related field with 1-3 years of relevant experience.


  • Strong molecular biology skills are required.
  • 1-2 years of experience with immunohistochemistry and immunofluorescence is preferred.
  • Technical experience in cell culture and aseptic technique is preferred.
  • Strong microscopy skills, including experience with confocal and digital pathology platforms is preferred.
  • Experience with multi-color flow cytometry is a plus.
  • Biotechnology or pharmaceutical industry experience with an emphasis in cancer biology is a plus.


  • Strong interpersonal skills with the ability to work both independently and collaboratively in a dynamic, cross-functional, and innovative research environment is required.
  • As this position will be interacting with internal and external personnel, strong communication, presentation, writing and computer skills are preferred.
  • Detail-oriented, with excellent organizational, and record-keeping skills is required.
  • Qualified candidates must be flexible and interested in learning new techniques and skills in accordance with the development of the technology and customer needs.
