Redwood City, CA /
Science /
The mission of Retro Biosciences is to extend healthy human lifespan by one decade.

We are a well-funded, untraditional bio startup based in Redwood City pursuing multiple programs, including blood plasma-inspired therapeutics. We do great science faster than academia and more agile than big pharma. We’re building a team of incredibly accomplished and kind individuals who embrace our culture of rapid iteration, transparency, and versatility.

We are looking to fill multiple scientist positions to help us understand then optimize aging blood plasma. If you have relevant experience and a strong drive to advance longevity biotech, we encourage you to apply. This specific position is for a molecular & cellular biologist that knows their way around a microscope and is capable of designing clever in vitro cellular assays.

Primary Responsibilities:

    • Creating cellular assays to optimally measure aging and rejuvenation in vitro, complementing our suite of omic assays
    • IHC and fluorescence microscopy of mammalian tissues
    • Automated image quantification
    • Interfacing closely with in vivo research staff and computational biologists


    • PhD in the biosciences and track record of excellence
    • Deep expertise in multiple forms of microscopy
    • Experience establishing new cell culture systems
    • Experience designing assays
    • Experience building new image quantification pipelines
    • Mastery of standard molecular biology techniques

Desirable Experience:

    • Postdoctoral/biotech/pharma experience
    • Protein purification and characterization
    • Generating and analyzing omic datasets
    • Some prior in vivo / rodent experience

You may be a good match for this role if:

    • You’re energetic, adaptable, and detail-oriented
    • You’re intellectually curious and deeply pragmatic
    • You communicate openly, clearly, and proactively
    • You can rapidly iterate and improve in a startup environment
    • You have a burning desire to understand the interplay between aging and blood biology through the lens of modern data-rich measurement technologies
In addition to an inspiring cause, we offer competitive pay, meaningful equity, daily lunch, infinite espressos, and a community of world-class scientists. If you're interested in this position, contact us and we'll send you some papers to read before the interview process.
