Are you ready to join our mission to enhance protein optimization and production?  Do you have a passion for applying innovative technology to create novel products?  Come be part of the Codexis Inc, Team where every day we get to unlock the power of proteins!. 

Since 2002, Codexis’ scientists and bioinformatics experts have worked collaboratively with our clients to do just that, enabling breakthrough developments for applications across multiple industries! As Codexis expands its footprint we are in constant need to find new ways to diversify applications of our CodeEvolverTM protein engineering platform.

But we can’t do it without YOU!

To help us reach our goals we are looking to hire a Scientist to join our Molecular and Cellular Engineering team.

If any of the below describes you, we would love to meet you!

  • Microbiologist with strong working knowledge of genetics and microbiology of Bacillus subtilis or other Bacillus strains
  • Ability to apply the knowledge to development of novel methods and workflows for protein engineering and expression of recombinant proteins in Bacillus subtilis
  • Collaborative, results-driven, learner

In this role you will be responsible for:

  • Design and construction of plasmids for high throughput and larger scale recombinant protein expression in Bacillus subtilis
  • Development of methods for generation and expression of enzyme variant libraries in the Bacillus host
  • Optimization of cultivation and recombinant protein expression in Bacillus
  • Development and optimization of strains, workflows and protocols for directed evolution in Bacillus host
  • Cloning of genes and genetic pathways, enzyme library generation, characterization of gene variants
  • Providing technical guidance for protein engineering projects
  • Analysis and interpretation of DNA sequencing data and assay data. Analysis and interpretation of contribution of mutations to desired properties of gene variants.
  • Working independently and with project teams to provide support and assistance to all phases of directed evolution projects, contribute to team presentations and written reports
  • Maintaining a safe and efficient work place, following safe lab practices and organizing lab environment.
