Job Details

Manufacturing Associate

  2025-12-31     b.next     San Francisco,CA  
Description:

b.next maintains Nucleus, the open source distribution and developer ecosystem for building synthetic cells. Instead of “editing” living cells, synthetic cell builders “compose” systems from individually validated components (DNA, RNA, proteins, small molecules). Designing, modeling, and testing compositions is much easier than living cells because you know and understand every component.

Our goal is to support the growing community of synthetic cell builders and to co-create a new field of biotechnology. To do so, we manufacture and validate components for developers and oversee the integration of new modules back into the Nucleus distribution. We also host Developer Notes, open-license preprints for rapidly and freely distributing data, protocols, and materials. In order to grow with the community, we need to prepare synthetic cell components at scale, and we need your help to do it.

b.next is looking to hire Manufacturing Associate(s) to run full-stack biomanufacturing for synthetic cellular components: media and buffer formulation and prep, bacterial strain preparation, biomass production, chromatography, polishing, quality control analytics, formulation, packaging, and shipping.

We're putting together the team that will discover the next generation of biomanufacturing. We value both immediate skills and future potential. Do you geek out about process? Do you like making things with your hands? Have a keen eye for detail? A vision of the full picture? Do you like to learn? Like to teach? Let's build together.

The team will run:

  • Media and buffer formulation and prep
  • E. coli strain preparation: DNA cloning, plating, small scale outgrowths, DNA sequencing
  • Ferment: shake flasks and benchtop scale (≤10 L) reactors
  • Preparatory and analytic FPLC
  • Automated liquid handling and custom formulation
  • Lyophilization: Formulation and machine operation
  • QC: Proteins, DNA, RNA, Ribosomes
  • Inventory Management
  • Shipping and Logistics

Teammates will excel at the following:

  • achieving high yield and quality preps
  • identifying upgrades from the line

    This is a full-time, salaried position with benefits (medical, dental, vision, 401(k)) based in the Dogpatch, San Francisco, starting immediately. If this is your team, email ...@bnext.bio.
