About Character Biosciences Character Biosciences is a precision medicine company pioneering targeted therapies for polygenic diseases, with an initial focus on ophthalmology. Our patient data platform integrates genomics with deep, longitudinal clinical and imaging data, enabling us to uncover genetic drivers of disease progression, advance novel therapeutics, and define patient stratification strategies that improve clinical success.

Our interdisciplinary team, comprising experts in clinical science, data science, statistical genetics, computer vision, and drug discovery, utilizes this platform to determine genetic drivers of disease progression, advance novel therapeutics and define genetics-based patient stratification. Powered by our data platform, Character Bio is currently advancing two programs in Dry Age-related Macular Degeneration (AMD) with additional programs for other disease areas (e.g. Glaucoma) in earlier stages of discovery research.

Founded in 2018, Character has raised capital from leading investors at the intersection of healthcare and technology, including an oversubscribed $110+ million Series B in 2025 co-led by aMoon and Luma Group, with participation from Bausch + Lomb, Sanofi Ventures, Innovation Endeavors, Catalio Capital Management, S32, KdT Ventures, and Jefferson Life Sciences. We also maintain a multi-target drug discovery collaboration with Bausch + Lomb to develop innovative precision medicines for AMD.

The Opportunity We are seeking a talented and highly motivated Research Associate/Senior Research Associate to join our Glaucoma Drug Discovery team. In this role, you will develop in vitro disease models and perform cell-based and in vitro assays to elucidate target biology, identify lead candidates and assess their mechanisms of action. This position offers an unique opportunity to contribute to the discovery and development of novel therapeutics, and also grow your career in a dynamic, thriving Biotech startup. This role is ideal for someone with hands-on experience in neuronal and glial cell culture and looking to make a difference in our fight to preserve vision.

This is an on-site laboratory position located at Brisbane, CA.
