Pay Rate Range: $40.00 - $44.53/hr on W2
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
  • Bachelor's or Master's 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
