Associate Scientist (Contract) – Protein Sciences
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:
o SDS-PAGE and Western blot
o UPLC/HPLC-based purity assessment
o 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
· 2–4+ 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
