The Opportunity

Esco Lifesciences Group is Singapore’s most globalized life sciences company, with annual revenues close to SGD 200M and global operations in over 42 locations and 26 direct countries across North America, Europe, Asia, Oceania. 


Esco Aster Pte Ltd is an affiliate of Esco Lifesciences Group and was first incorporated in 2017. 


Esco Aster is a contract research development and manufacturing organization founded and deeply rooted by scientists enabling fellow scientists to translate their bench work into commercially available products at affordable prices.


Our scientific work is in emerging and frontier biology utilizing cells as a final product or deriving products from cells which often we use cells as the factory to derive our target product. 


Our first commercial breakthrough success is Esco Aster is commercially first in class being first in the world to be certified for cultivated/cell-based meat to FSSC 22000 and by a competent food regulatory body.


We are first in the region to operate an end-to-end integrated full cell line creation/immortalization or engineered cell line, cell culture process development, analytical development for stem cells and exosomes with full cGMP Capabilities from Drug Substance and small-scale fill & finish for final Cell Therapy Product.


The work we do creates a remarkable and lasting impact on our world. We offer you an opportunity to be part of this exciting journey to own your career and firsthand exposure to new emerging modalities supporting translational sciences.

Join us as we redefine BioSolutions for One World and One Health for the current and future generations to come.
