Research Associate I / II - Biologics Purification & Characterization

About Worldwide Research & Development (WWRD)

BioMarin's WWRD organization spans early research through post-market clinical development and includes the scientific teams responsible for discovery, translational research, and development. Our collaborative environment emphasizes scientific rigor, innovation, and meaningful patient impact.

Position Summary
The Therapeutics Process Development & Characterization (TPDC) group is seeking a highly motivated temporary Research Associate I/II to support biologics purification and analytical characterization, with a primary focus on enzymes, and additional exposure to other therapeutic proteins, antibodies, and peptide-based modalities.
This is a primarily laboratory-based role involving hands-on purification and characterization of biologics using established chromatography and filtration workflows. The successful candidate will support multiple early-stage and exploratory research programs across BioMarin. Occasional responsibilities may include basic instrument and equipment maintenance in support of laboratory operations.
The ideal candidate is detail-oriented, organized, and able to work independently with guidance in a fast-paced research environment.

Duties & Responsibilities
Protein & Biologic Purification
* Perform purification of recombinant enzymes and other therapeutic biologics, including proteins, antibodies, and peptides, using standard chromatography systems (e.g., AKTA Pure, AKTA Avant).
* Execute purification workflows including:
o Affinity chromatography
o Ion exchange chromatography (AEX/CEX)
o Size-exclusion chromatography (SEC)
o Hydrophobic interaction chromatography (HIC)
o Desalting and buffer exchange
* Perform concentration and buffer exchange using tangential-flow filtration (TFF) or centrifugal filtration.
* Prepare buffers and reagents according to established protocols.
* Support routine equipment checks, basic instrument maintenance, and troubleshooting as needed.

Analytical Characterization
* Perform analytical assays to assess purity, identity, and concentration of biologics, including:
o SDS-PAGE, CE-SDS
o SEC-HPLC, RP-HPLC
o UV/Vis spectrophotometry
o Other established protein or peptide analytical methods as required
* Execute established methods with an emphasis on data quality, reproducibility, and documentation.
* Assist with basic data analysis and communication of results to project teams.

General Laboratory Responsibilities
* Maintain accurate and complete electronic and/or paper laboratory notebooks.
* Follow established SOPs and document deviations with guidance.
* Communicate results, observations, and progress updates clearly within the team.
* Contribute to a safe, clean, and well-organized laboratory environment in compliance with BioMarin safety standards.

Education & Experience
Research Associate I
* Bachelor's degree in Biochemistry, Biology, Chemical Engineering, or a related discipline.
* 0-2 years of relevant hands-on laboratory experience (academic or industry).

Research Associate II
* Bachelor's degree with 2+ years of relevant experience, or
* Master's degree with 1-2 years of relevant experience.
* Prior experience with biologics purification (enzymes, proteins, antibodies, or peptides) strongly preferred.
* Experience with FPLC/HPLC and common protein analytical techniques is highly desirable.

Desired Skills
* Familiarity with AKTA Pure/Avant or similar chromatography instrumentation.
* Strong attention to detail, organization, and reliable documentation practices.
* Ability to follow established workflows and troubleshoot with guidance.
* Effective communication and collaboration skills.
* Working knowledge of Microsoft Office; familiarity with data analysis tools (e.g., GraphPad Prism, JMP) is a plus.
