Associate Scientist (Contract) Protein Sciences

Title: Associate Scientist (Contract) Protein Sciences
Location : Foster City CA
Duration : 06+ Months
Pay Range : $40/hr- $44.21/hr

Position Summary

• We are seeking a highly motivated Associate Scientist (Contract) to support our Protein Sciences team. This individual will contribute as a hands-on laboratory scientist, executing protein production, purification, and analytical workflows that support multiple CAR-T and cell therapy programs.
• This is a 100% bench-focused, individual contributor role. The successful candidate will work closely with scientists across Protein Science and Research to generate high-quality data and reagents, while contributing to efficient laboratory operations and experimental execution.

Key Responsibilities
Protein Production & Purification

• Execute recombinant protein expression and purification workflows across multiple expression systems (e.g., mammalian cell culture, transient transfections)
• Perform protein purification using AKTA chromatography systems (affinity, SEC, ion exchange)
• Maintain cell cultures and support transfection workflows

Analytical Characterization
Perform biochemical and biophysical characterization of proteins and antibodies, including:

• SDS-PAGE and Western blot
• UPLC/HPLC-based purity assessment
• Binding assays (e.g., Octet/BLI)
• Document and summarize experimental data clearly to support team decision-making

Protein Modification & Assay Support

• Perform antibody and protein conjugation workflows with appropriate analytical follow-up

Prepare reagents and materials to support downstream functional assays (e.g., flow cytometry or cell-based assays in collaboration with Cell Biology partners)

Lab Operations & Execution

• Maintain organized lab practices, including reagents, consumables, and shared equipment
• Ensure accurate experimental documentation in electronic lab notebooks and LIMS
• Follow established SOPs and contribute to maintaining reproducibility and data quality standards

Collaboration

• Work closely with cross-functional partners to execute experiments aligned with defined protocols and timelines
• Communicate experimental progress and results effectively to project teams

Basic Qualifications

• Bachelors or Masters degree in Biochemistry, Molecular Biology, Protein Science, or related field
• 24+ years of relevant hands-on laboratory experience in academic or industry settings

Preferred Qualifications

• Experience with recombinant protein expression and purification workflows
• Hands-on experience with AKTA systems and chromatography methods
• Familiarity with protein characterization techniques (SDS-PAGE, HPLC, BLI/Octet, etc.)
• Experience with mammalian cell culture and transfections
• Strong attention to detail and commitment to high-quality data generation and documentation
• Ability to follow protocols, troubleshoot at the experiment level, and work effectively in a fast-paced lab environment

Key Characteristics for Success in This Role

• Strong hands-on bench execution skills
• High level of organization and reproducibility
• Ability to independently execute experiments with appropriate controls
• Collaborative mindset and willingness to support team priorities
