About Curie Co

Curie Co is a life science company that engineers enzymes and marine biomaterials to replace harmful and banned chemicals.

Job Description

Curie Co uses the power of biotechnology to replace petrochemicals in everyday products, with more sustainable, engineered enzymes. We’re looking for team members passionate about achieving this mission and contributing to the biomanufacturing revolution. Individuals with exceptional multitasking skills, attention to detail, and self-motivated with the ability to work independently and thrive in a fast-paced environment. Excellent relational, communication, and presentation skills are highly regarded to help continue to foster a collaborative and learning environment.
Curie Co is recruiting an experienced bioprocessing engineer to develop downstream workflows and unit operations to purify recombinant proteins from a variety of expression systems. This individual will work closely with fellow scientists and RAs to prototype and optimize processes to improve yields and time to results. This role also provides an opportunity to work with others within biotechnology in establishing and managing CMO and external partner relationships.

Main Responsibilities:

    • Develop commercially scalable processes for the purification of recombinant proteins and enzymes expressed in microbial hosts (e.g., bacteria or yeast)
    • Develop unit operations at pilot scale to 100 liters
    • Prepare technology transfer documents including detailed process descriptions, mass balances, and process flow diagrams (PFD’s)
    • Manage CMO and external partner relationships including tech transfer
    • Participate and advise in the development of final product specifications
    • Implement and execute the purification of recombinant proteins
    • Collaboratively design and execute experiments (DOE), analyze data, write and review technical reports and protocols, and present during team meetings
    • Research, learn, and incorporate promising techniques and technologies in protein purification


    • Degree in Chemical Engineering or related discipline with a minimum of 3 years of industrial biotech experience
    • Experience with lab-scale and pilot-scale unit operations
    • Sound understanding of protein biochemistry and recombinant protein expression in microbial hosts as it relates to downstream purification
    • Strong technical background and direct hands-on experience with large scale protein purification and downstream processing unit operations such as preparative chromatography, centrifugation, homogenization, diafiltration, and tangential flow filtration 

Preferred Qualifications:

  • Proficiency is a plus: ammonium sulfate precipitation, or purification from bacterial inclusion bodies
  • Proficiency is a plus: protein purification using affinity, size exclusion, ion exchange, and hydrophobic interaction chromatography
  • Experience with final formulation, granulation, spray drying is a plus
  • Knowledge of available systems and vendors in downstream processing
