QC Specialist II

Cytek Biosciences is a pioneering company in cell-analysis, driven by its patented Full Spectrum Profiling (FSP) technology, which captures the entire fluorescent emission spectrum to deliver ultra-sensitive, high-parameter flow cytometry. With this breakthrough, Cytek empowers researchers with richer biological insights - without the trade-offs of traditional cytometry.

Our San Diego site is a critical part of our operations: it's a reagent manufacturing facility that produces key product lines including cFluor, Guava, Muse, and Tonbo reagents. This location is ISO 13485 certified, demonstrating our rigorous commitment to quality and compliance.

As a QC Specialist II in our San Diego facility, you'll be an essential member of the Operations team. You will perform quality testing on fluorescently labeled bioconjugates and purified antibodies using flow cytometry, ensuring that our reagent products meet Cytek's exacting performance and consistency standards.
